What Comes First a PhD or a Masters? Definition, Purpose, and Examples

By Dr. Aanya Mehta
Research Writer & Professional Business Communicator

If you are planning postgraduate study, one of the first questions you may ask is: What comes first a PhD or a Masters? In the traditional academic pathway, a master’s degree comes before a PhD. You normally complete a bachelor’s degree, progress to a master’s degree, and then undertake doctoral research. However, that sequence is not universal. Some universities and doctoral programs allow academically strong candidates to enter a PhD directly after a bachelor’s degree, while others expect or explicitly require master’s-level preparation.

The difference matters because a master’s and a PhD are designed for different academic purposes. A master’s degree generally develops advanced subject knowledge, specialist professional capability, or early research skills. A PhD is a doctoral research degree centred on producing a substantial, original contribution to knowledge. Consequently, the question is not simply which qualification ranks higher. You also need to consider which level of preparation your chosen PhD program expects and which route best prepares you for independent research.

Requirements vary significantly between countries, universities, disciplines, and individual departments. Princeton University, for example, states that a master’s degree is not required for application to its PhD programs; applicants need a bachelor’s degree or international equivalent. By contrast, several Oxford DPhil programs explicitly require both an undergraduate degree and a relevant master’s qualification, although requirements differ across departments. Cambridge similarly notes that in most faculties, students are expected to have completed postgraduate study—normally a research-preparation master’s—before starting a PhD, while different routes may still be available.

For that reason, the safest answer is: a master’s usually comes before a PhD, but you should never assume that you must complete a master’s before applying for doctoral study. Check the exact entry requirements of the university, department, and PhD project you are considering.

This guide explains the degree hierarchy, the purpose of each qualification, direct-entry PhD routes, country and discipline differences, practical examples, and how to decide whether completing a master’s first is the right academic choice for you.

Quick Answer: What Comes First, a PhD or a Master’s?

A master’s degree normally comes before a PhD in the conventional academic sequence:

Bachelor’s degree → Master’s degree → PhD

A master’s is a postgraduate qualification that usually provides advanced subject knowledge and, depending on the program, research training. A PhD is a doctoral qualification involving sustained independent research and the production of an original contribution to knowledge.

However, you do not always need a master’s degree before a PhD. Some universities admit suitable candidates directly from a bachelor’s or honours degree. Princeton explicitly states that a master’s is not required to apply for a PhD, while Australian National University allows entry through an appropriate bachelor’s honours qualification or equivalent research preparation.

Other doctoral programs expect substantial postgraduate preparation. For example, Oxford’s DPhil in Education requires a relevant master’s alongside a strong undergraduate degree.

Therefore, your next step should be to check program-specific admission criteria, rather than relying only on the general degree hierarchy.

Methodology and Academic Sources

This article uses established higher-education terminology and current official university admissions guidance to explain postgraduate and doctoral pathways. The editorial brief requires people-first, evidence-aware guidance while avoiding universal academic rules where institutional requirements vary.

Examples from universities are illustrative rather than universal. Admissions policies can differ by faculty, discipline, program, research project, applicant background, and year of entry. Always check the current requirements published by the university and department to which you intend to apply.

What Is a Master’s Degree?

A master’s degree is an advanced postgraduate qualification usually completed after a bachelor’s degree. It allows students to deepen their expertise in a subject, develop specialised professional capabilities, undertake advanced coursework, gain research training, or combine these elements.

Master’s programs can differ considerably.

Common forms include:

• Master of Arts (MA)
• Master of Science (MSc or MS)
• Master of Research (MRes)
• Master of Philosophy (MPhil)
• Master of Engineering (MEng)
• Master of Business Administration (MBA)
• Discipline-specific professional master’s degrees

Some master’s programs are primarily coursework-based. Others contain a substantial thesis or dissertation. Research-oriented master’s degrees can be particularly useful preparation for doctoral study because students learn how to formulate research questions, work with academic literature, select research methods, analyse evidence, and produce extended scholarly writing.

A master’s can therefore act as a bridge between undergraduate learning and independent doctoral research.

However, it is important not to assume that every master’s automatically prepares a student for a PhD. A professional coursework master’s with little or no research component may be viewed differently from a research-intensive master’s when a doctoral admissions committee evaluates research readiness.

What Is a PhD?

A PhD, or Doctor of Philosophy, is an advanced doctoral research degree. Despite its name, PhDs are awarded in fields far beyond philosophy, including science, engineering, medicine-related research, education, business, economics, social sciences, humanities, computing, and many other disciplines.

The defining feature of a PhD is independent research.

A doctoral candidate normally works under academic supervision to investigate a clearly defined research problem. The candidate typically reviews existing scholarship, establishes appropriate research methods, conducts original investigation or analysis, interprets findings, and produces a thesis or dissertation that demonstrates an original contribution to the field.

Cambridge describes the PhD as its principal research degree and notes that it involves several years of advanced study and research. Harvard’s Biological and Biomedical Sciences guidance similarly describes the dissertation as containing substantial independent research work and requiring successful examination and defence.

A PhD should therefore not be understood merely as “more classes after a master’s.” It represents a transition toward research independence, scholarly specialisation, and knowledge creation.

Master’s vs PhD: What Is the Difference?

The simplest distinction is that a master’s generally develops advanced knowledge and research capability, whereas a PhD requires a much deeper level of independent research.

Aspect	Master’s Degree	PhD
Academic level	Postgraduate	Doctoral
Usual position	After bachelor’s	Usually after bachelor’s and often after master’s
Main purpose	Advanced knowledge, specialisation or research preparation	Original independent research
Typical structure	Coursework, research, or both	Primarily research, sometimes with coursework/training
Research expectations	Vary from limited to substantial	Extensive
Major project	May include thesis/dissertation	Doctoral thesis/dissertation normally central
Independence	Developing	High
Academic outcome	Advanced subject mastery	Original contribution to knowledge
Entry requirement for next stage	May support PhD entry	Usually terminal research qualification

The most important practical point is that degree level and admission sequence are not exactly the same thing.

A PhD is academically higher than a master’s, but that does not mean every PhD applicant must already possess a master’s.

What Comes First a PhD or a Masters?

In the most familiar academic sequence, the master’s comes first and the PhD comes afterward.

The pathway looks like this:

1. Complete a bachelor’s degree.
2. Complete a master’s degree.
3. Apply for a PhD.
4. Complete doctoral research.
5. Submit and defend or otherwise undergo examination of the doctoral thesis according to institutional requirements.

This remains a common route because master’s-level study can give students valuable preparation for the demands of doctoral research.

Nevertheless, higher education systems are not globally uniform.

An alternative route can be:

1. Complete a bachelor’s or bachelor’s honours degree.
2. Demonstrate sufficient academic and research preparation.
3. Apply directly to a PhD.
4. Complete any doctoral coursework or research training required by the program.
5. Progress to independent doctoral research.

Princeton provides a clear example of the second model: its Graduate School states that applicants do not need a master’s before applying to a PhD, although a bachelor’s or international equivalent is required.

Australian institutions may use honours-level research preparation as another route. ANU states that a relevant bachelor’s degree with appropriate honours can meet its minimum PhD admission requirements, alongside other recognised routes involving research qualifications or equivalent experience.

So, in hierarchy, the master’s is below the PhD. In sequence, it commonly comes first—but it is not always mandatory.

Do You Need a Master’s Before a PhD?

No. A master’s degree is not universally required before a PhD.

Whether you need one depends on the admission policy for the specific doctoral program.

There are roughly three common models.

Model 1: A master’s is explicitly required

Some programs expect both undergraduate and master’s qualifications.

For example, Oxford’s DPhil in Education currently specifies a relevant master’s qualification as part of its minimum academic requirements, together with a strong undergraduate degree. Oxford’s DPhil in English similarly expects both undergraduate and master’s-level preparation.

In these cases, completing a master’s is effectively part of the normal route to doctoral eligibility.

Model 2: A master’s is preferred or commonly completed but not always mandatory

A university may permit alternative forms of preparation while indicating that postgraduate study is common.

Cambridge explains that in most faculties, candidates are expected to have completed a year of postgraduate study, normally through a research-preparation master’s, before beginning a PhD. It also notes that different routes are possible depending on the offer and program.

Model 3: Direct entry from a bachelor’s is permitted

Some doctoral systems allow qualified students to enter directly after undergraduate study.

Princeton states unequivocally that a master’s is not required to apply to a PhD. Its Mechanical and Aerospace Engineering department likewise allows direct PhD applications without a master’s.

Oxford’s Experimental Psychology department provides another useful reminder that even within one university, requirements differ between programs: it states that a master’s is not necessary before applying for its DPhil route.

This is why checking the departmental page, rather than relying only on general university information, is essential.

Why Do Some Universities Require a Master’s Before a PhD?

Universities may require a master’s because doctoral study demands evidence that you are prepared for advanced independent research.

A research-oriented master’s may demonstrate several capabilities.

Research-methods training

You may have learned qualitative, quantitative, experimental, computational, archival, textual, or mixed-method research approaches relevant to your discipline.

Extended academic writing

A dissertation or research thesis shows whether you can sustain a complex argument over a substantial piece of scholarly work.

Literature engagement

Doctoral researchers must understand existing scholarship well enough to identify gaps, debates, methodological limitations, or unresolved problems.

Independent project management

Research involves planning, ethical approvals where required, data collection or source analysis, documentation, revision, and lengthy periods of self-directed work.

Subject specialisation

A master’s can help narrow broad undergraduate interests into a researchable doctoral topic.

In fields where doctoral projects expect substantial prior research experience, this preparation can be especially important.

However, universities may accept other evidence of equivalent preparation—for example, an honours thesis, research publications, substantial research employment, or relevant professional experience—depending on their regulations.

Can You Go Straight From a Bachelor’s to a PhD?

Yes, in some programs you can enter a PhD directly after a bachelor’s degree.

But direct eligibility does not mean admission is automatic.

A university may consider:

• Undergraduate grades
• Honours classification
• Research experience
• Undergraduate thesis or capstone research
• Academic references
• Research proposal
• Statement of purpose
• Writing sample
• Relevant technical knowledge
• Fit with available supervisors
• Research resources
• English-language requirements where applicable
• Program-specific prerequisites

At ANU, for example, an appropriate Australian bachelor’s degree with upper second-class honours or international equivalent is one recognised route to PhD admission. Other qualifications or relevant research achievements may also be considered.

The University of Melbourne similarly explains that a master’s is not always necessary for graduate research and that some applicants may qualify through a four-year bachelor honours degree or equivalent qualifications and experience.

Direct entry therefore works best for students whose undergraduate education has already provided substantial research preparation.

How the Master’s-to-PhD Pathway Can Differ by Country

Academic pathways vary internationally, so statements such as “everyone needs a master’s before a PhD” are too broad.

United States

Many US doctoral programs allow applicants to enter directly after completing a bachelor’s degree. The PhD itself may contain substantial coursework, examinations, research training, and milestones before the dissertation stage.

Princeton is a clear example: its Graduate School requires a bachelor’s degree or equivalent for PhD applicants but does not require a master’s.

Some students may also receive a master’s qualification during their doctoral study. Harvard, for example, describes master’s-in-passing arrangements within certain PhD programs.

United Kingdom

The UK picture is more varied than a simple rule suggests.

Cambridge says that most faculties expect postgraduate preparation, usually a research-preparation master’s, before a PhD.

Oxford demonstrates substantial program-level variation. Its DPhil programs in fields such as Education and English specify master’s-level requirements, while Experimental Psychology states that completing a master’s before applying is not necessary.

Australia

Australian universities commonly recognise a strong four-year honours degree with significant research preparation as a route to doctoral study.

ANU lists an Australian bachelor’s degree with appropriate honours as one pathway into a PhD. The University of Melbourne likewise states that graduate research entry may be based on a relevant master’s or a four-year bachelor honours qualification containing substantial research.

These examples illustrate why international students should compare their qualifications with the university’s published equivalency requirements rather than assuming that a degree title will be interpreted identically across countries.

Should You Do a Master’s Before a PhD Even If It Is Not Required?

Sometimes, yes.

The real decision is not simply, “Can I enter a PhD without a master’s?” A better question is, “Am I sufficiently prepared for the kind of research this PhD requires?”

A master’s may be worthwhile when you need to strengthen one or more of the following areas.

1. Your research experience is limited

If your bachelor’s degree contained little independent research, a research-focused master’s can help you learn what research actually involves before committing several years to a doctorate.

2. You are changing disciplines

Suppose your undergraduate degree is in engineering but you want to research technology policy. A relevant master’s may help you build theoretical knowledge, methodological competence, and academic credibility in the new field.

3. Your research interests are still broad

A master’s provides time to explore a discipline more deeply before defining the narrower question required for doctoral research.

4. You want to strengthen your academic record

Strong postgraduate performance may demonstrate academic development. Whether it compensates for weaker undergraduate results depends entirely on the university and program.

5. Your intended PhD program requires it

If the department specifies a master’s as a minimum qualification, the decision is straightforward: you must satisfy that requirement or an explicitly recognised equivalent route.

6. You want experience writing a substantial dissertation

Completing a master’s thesis can reveal whether you enjoy long-term research, iterative writing, criticism, methodological problem-solving, and independent academic work.

When Going Directly to a PhD May Make Sense

Direct PhD entry may be appropriate when:

• Your target program explicitly accepts bachelor’s graduates
• You completed a strong honours or undergraduate research thesis
• You already have significant research experience
• Your academic background closely matches the proposed doctoral field
• You have identified a viable research area
• You understand what doctoral work involves
• You have strong academic references
• You meet program-specific requirements
• The PhD provides the coursework and research training you still need

Direct entry can avoid completing a separate qualification merely as a procedural step.

However, saving time should not be your only reason.

A PhD is a demanding research commitment. Entering before you have developed sufficient methodological, intellectual, or academic-writing foundations can make the transition more difficult.

Practical Example 1: Direct PhD Entry After a Strong Bachelor’s Degree

Consider Maya, who completes a four-year undergraduate science degree with a substantial honours research project.

During her final year she:

• Conducts supervised laboratory research
• Learns research design and statistical analysis
• Writes an extended research thesis
• Presents findings
• Develops a clear interest in a specific scientific problem
• Receives strong references from research-active academics

Maya identifies a doctoral program that explicitly permits applicants with an appropriate bachelor’s honours degree.

In this situation, applying directly to the PhD may be reasonable. Completing a separate master’s solely because she believes that “a master’s always has to come before a PhD” could be unnecessary.

Why this route works: Maya already has evidence of research preparation, and her target program accepts applicants with her academic pathway.

Practical Example 2: A Master’s as Preparation for Doctoral Research

Arjun completes a three-year bachelor’s degree in business. His course is primarily classroom-based and includes only a small final project.

Several years later, he becomes interested in doctoral research examining how digital transformation affects organisational decision-making.

Although Arjun has professional experience, he has limited formal training in:

• Research philosophy
• Research design
• Qualitative interviewing
• Quantitative analysis
• Academic literature review
• Research ethics
• Dissertation writing

A research-oriented master’s could help him convert a broad professional interest into an academically grounded research problem.

During the master’s, he may learn to distinguish between an interesting business issue and a feasible research question, develop methodological skills, and complete a dissertation.

Why the master’s helps: It is not merely another credential. It provides research preparation that his previous education did not offer.

Practical Example 3: A Master’s Required by the Target PhD

Sofia earns a strong undergraduate degree and decides that she wants to pursue doctoral research in a humanities field.

She reviews several programs and discovers that her preferred doctoral course requires both a strong undergraduate qualification and a relevant master’s degree.

In this case, Sofia should not rely on general internet advice claiming that students can “skip the master’s.”

Her target program determines the requirement.

She can use her master’s strategically to:

1. Develop specialist subject knowledge.
2. Identify a research gap.
3. Build relationships with academic researchers.
4. Complete a strong dissertation.
5. Refine her doctoral proposal.
6. Demonstrate readiness for advanced research.

Why this route works: The master’s satisfies an admission requirement while also strengthening Sofia’s doctoral preparation.

Practical Example 4: Changing Academic Fields

Daniel has a bachelor’s degree in computer science but becomes interested in researching educational technology from a social-science perspective.

Technically, he finds doctoral programs that accept bachelor’s-level applicants. Yet he has little background in:

• Education theory
• Social-science research design
• Qualitative research
• Education policy
• Relevant scholarly literature

Going directly into a PhD may therefore be possible but not necessarily academically sensible.

A master’s in education, learning sciences, educational technology, or a related research field could help Daniel acquire the disciplinary foundations needed to frame a credible doctoral project.

The lesson: Eligibility and readiness are different questions.

Master’s First or Direct PhD? A Decision Guide

Your Situation	Master’s First May Be Better	Direct PhD May Be Reasonable
Little research experience	Yes	Usually less suitable
Strong honours thesis	Possibly	Often worth exploring
Changing academic fields	Often	Depends on prior preparation
Target PhD requires a master’s	Yes	No, unless an equivalent route is explicitly permitted
Target PhD accepts bachelor’s graduates	Optional	Yes
Uncertain research interests	Often helpful	Consider carefully
Extensive relevant research experience	Depends	Potentially
Need advanced methodology training	Often	If PhD provides sufficient training
Strong research proposal and supervisor fit	Helpful but not always necessary	Potentially
Primarily trying to “save time”	Reassess motivation	Not sufficient by itself

The practical takeaway is simple: choose the route that best matches the requirements and preparation needed for your intended research—not the route with the fewest degree titles.

What Should You Look for in PhD Admission Requirements?

When reviewing doctoral programs, do not stop after reading “minimum degree required.”

Look carefully at the complete admissions page.

Check:

1. Academic qualification requirements
   Does the program require a bachelor’s, honours degree, master’s, or research master’s?
2. Research component requirements
   Does your previous qualification need to include a thesis or substantial independent research?
3. Minimum grades or classifications
   Requirements can differ considerably across universities and disciplines.
4. Subject relevance
   Does your previous degree need to be in the same discipline?
5. Research proposal requirements
   Some doctoral applications require a detailed proposal; others admit students into broader research programs.
6. Supervisor requirements
   Some universities expect applicants to identify a supervisor before formally applying. The University of Melbourne states that most of its graduate research programs require potential supervisor support before application.
7. English-language requirements
   These may apply when previous education does not satisfy the institution’s language criteria.
8. Professional or research experience
   Some institutions can consider equivalent research capability, but the meaning of equivalence is program-specific.
9. Funding and scholarship criteria
   Eligibility for admission does not necessarily mean that you meet the criteria for a particular scholarship.
10. Current year requirements
    Always make sure you are reading information for your intended entry year.

Common Mistakes When Planning a Master’s or PhD

Mistake 1: Assuming a master’s is mandatory everywhere

It is not.

Better approach: Check the individual PhD program. Princeton, for example, permits PhD applications without a prior master’s.

Mistake 2: Assuming a master’s is never necessary

This is equally inaccurate.

Some doctoral programs explicitly require master’s-level preparation.

Better approach: Treat university and departmental admission criteria as authoritative for that application.

Mistake 3: Choosing a master’s only because it “comes next”

Your master’s should support a clear academic, research, or professional purpose.

Better approach: Ask what capabilities the degree will develop and whether those capabilities matter for your intended PhD.

Mistake 4: Confusing coursework experience with research preparation

High grades in taught modules do not automatically demonstrate readiness for independent doctoral research.

Better approach: Examine your experience with research design, evidence, methodology, extended academic writing, and independent investigation.

Mistake 5: Focusing only on qualification titles

Two applicants with the same nominal degree can have very different research backgrounds.

Better approach: Evaluate the actual content of your degree, especially the research component.

Mistake 6: Ignoring discipline differences

A route that is common in engineering or experimental science may not match the expectations of history, education, literature, business, psychology, or another field.

Better approach: Investigate your discipline specifically.

Mistake 7: Applying before understanding the research question

A PhD requires a much narrower and deeper research focus than many students initially expect.

Better approach: Read current scholarship, identify potential supervisors, and clarify the problem you want to investigate.

Mistake 8: Assuming minimum eligibility means competitive admission

Meeting the minimum requirements only establishes that your application may be considered. It does not guarantee admission.

ANU explicitly notes that admission to most programs is competitive and meeting minimum requirements does not automatically guarantee entry.

Checklist: Are You Ready to Choose Between a Master’s and a PhD?

Before making your decision, ask yourself:

• Have I checked the current entry requirements of my target PhD?
• Does the program explicitly require a master’s?
• If not, does it accept my type of bachelor’s or honours degree?
• Have I completed substantial independent research?
• Can I explain the research problem I want to investigate?
• Do I understand the main academic literature in the area?
• Do I have the methodological skills required for the proposed research?
• Have I completed an extended research paper, thesis, or dissertation?
• Am I moving into a different academic discipline?
• Would a master’s provide essential subject or research preparation?
• Have I investigated potential supervisors?
• Have I checked funding and scholarship requirements separately?
• Have I compared several programs instead of assuming all universities use the same model?
• Do I understand the time commitment involved in doctoral research?
• Am I pursuing a PhD because it serves a meaningful research or career goal?

If several answers remain uncertain, a research-oriented master’s may give you useful preparation and decision-making time. If you already possess strong research credentials and your intended program supports direct entry, applying directly to the PhD may be appropriate.

How to Prepare Academically for a PhD

Whether you enter after a bachelor’s or a master’s, strong doctoral preparation usually involves more than obtaining the required degree.

Develop a research-focused reading habit

Move beyond textbooks and become comfortable reading peer-reviewed journal articles, scholarly books, conference papers, and other authoritative literature in your field.

Learn how research arguments are constructed

Pay attention to how published researchers:

• Define problems
• Review previous research
• Identify gaps
• Formulate questions or hypotheses
• Justify methods
• Present evidence
• Acknowledge limitations
• Interpret findings

Strengthen methodological knowledge

Your methodology should be suitable for the research question rather than selected simply because you already know how to use it.

Practise extended academic writing

Doctoral writing requires structure, clarity, precision, evidence, argumentation, revision, and consistent citation practices.

If you are preparing a manuscript, research paper, or early doctoral work and need language and structural review, professional research paper editing support can help improve communication while leaving the researcher’s intellectual contribution and final decisions with the researcher.

Understand academic integrity

You remain responsible for your:

• Research questions
• Data
• Methods
• Analysis
• Interpretations
• Claims
• Citations
• References
• Final submitted work

Any editing, writing guidance, or AI-assisted support should be used in accordance with your institution’s rules.

How Contentxprtz Can Support Master’s and PhD Researchers

Choosing the correct postgraduate pathway is only one part of preparing for advanced research. Once a student begins developing a proposal, thesis, dissertation, research paper, or journal manuscript, clarity of academic communication becomes increasingly important.

Contentxprtz provides academic communication support designed to help researchers improve the presentation of their own work without replacing their intellectual contribution.

Depending on the researcher’s needs, relevant support may include:

• Academic language editing
• Research paper editing
• Thesis and dissertation editing
• Structural and clarity review
• Proofreading
• Citation and referencing review
• Research-writing guidance
• Review of alignment between research questions, objectives, methods, and manuscript sections

Researchers preparing longer postgraduate work can explore thesis writing and editing services or dissertation writing and editing services where appropriate.

Professional editing should strengthen clarity and communication while preserving the researcher’s ideas, evidence, interpretation, and responsibility for the final submission. University policies on third-party editing and AI-assisted support can differ, so researchers should always check their institution’s academic-integrity requirements.

Summary: What Comes First a PhD or a Masters?

A master’s normally comes before a PhD in the traditional academic sequence, but a master’s is not a universal requirement for doctoral admission.

The standard sequence is:

Bachelor’s → Master’s → PhD

However, another legitimate pathway is:

Bachelor’s or honours degree → PhD

The correct route depends on your university, country, discipline, research experience, and doctoral program.

A master’s can be especially valuable when you need:

• More research experience
• Advanced methodological training
• A stronger academic foundation
• Experience writing a dissertation
• Preparation for a different discipline
• Time to refine your research interests

Direct PhD entry can make sense when your target program permits it and your previous education already demonstrates strong research readiness.

Most importantly, do not plan your postgraduate education according to a universal formula. Read the current admission requirements for each specific PhD program and evaluate whether you are genuinely prepared for independent research.

Frequently Asked Questions

1. What is the difference between a master’s and a PhD?

A master’s is an advanced postgraduate qualification, while a PhD is a doctoral research qualification and is academically higher.

A master’s typically develops specialised subject knowledge, professional expertise, research ability, or a combination of these. Some programs are largely coursework-based, while others include a substantial dissertation or thesis.

A PhD is centred much more heavily on independent research. Doctoral candidates normally investigate a specific problem over several years and produce a substantial thesis or dissertation demonstrating an original contribution to knowledge.

For students considering an academic research career, the master’s may therefore function as preparation for doctoral work. However, because some PhD programs admit candidates directly after a suitable bachelor’s or honours degree, the master’s is not always a compulsory intermediate qualification.

2. How do I understand what comes first a PhD or a Masters?

In the conventional academic sequence, the master’s comes before the PhD:

Bachelor’s → Master’s → PhD.

However, when asking what comes first a PhD or a Masters, remember that academic hierarchy and admission requirements are slightly different questions.

A PhD is the higher qualification, but some universities allow students to enter a PhD directly from a strong bachelor’s or honours degree. Princeton, for example, states that a master’s is not required for PhD application.

Therefore, use the traditional sequence as a general guide, but check the exact requirements for the department and doctoral program you want to join.

3. Do I need a master’s degree before applying for a PhD?

Not always.

Some universities require a relevant master’s degree, some strongly prefer postgraduate research preparation, and others accept applicants directly from undergraduate study.

Oxford’s DPhil requirements illustrate how expectations can vary even between programs within the same university. Some courses specify a master’s, whereas Oxford Experimental Psychology states that prior completion of a master’s is not necessary for its DPhil application route.

Never rely on a general statement such as “you need a master’s for a PhD” or “you can always skip the master’s.” Read the current program-level admissions criteria.

4. Can I go directly from a bachelor’s degree to a PhD?

Yes, if your intended PhD program permits direct entry and your academic background meets its requirements.

This pathway is common in some doctoral systems and disciplines. Princeton permits applicants with a bachelor’s or international equivalent to apply directly to its PhD programs without a master’s. Australian universities may also recognise strong honours-level undergraduate research preparation. ANU, for example, lists an appropriate bachelor’s honours degree as one route into doctoral study.

You should still evaluate whether you have sufficient research experience, methodological knowledge, academic-writing ability, and clarity about your proposed area of study.

5. Is it better to complete a master’s before a PhD?

A master’s may be better if it gives you preparation you genuinely need. It is not automatically better simply because it adds another qualification.

Consider completing a master’s first if your undergraduate degree included limited research, you are changing disciplines, you have not yet developed a clear research area, or you need advanced methodological training.

A master’s can also let you experience substantial research before committing to a longer doctoral project.

By contrast, if you already have strong honours-level research experience and your chosen PhD explicitly welcomes direct applicants, completing another degree first may not be necessary.

The best route is the one that makes you academically prepared and meets the requirements of your target program.

6. Can you earn a master’s while completing a PhD?

In some doctoral programs, yes.

Certain universities offer an intermediate or “master’s in passing” qualification after a doctoral student completes specified coursework, examinations, research milestones, or other requirements.

Harvard’s Biological and Biomedical Sciences program, for example, describes an AM master’s degree that eligible PhD students may receive en route after meeting specified requirements.

This arrangement should not be confused with completing an independent master’s degree before applying for the PhD. Rules differ widely between institutions, so check your doctoral program’s handbook rather than assuming that an intermediate master’s will automatically be awarded.

7. How long should I study for a master’s before starting a PhD?

There is no universal duration because master’s structures differ internationally.

Some are relatively compact taught programs, while research master’s degrees may involve substantially more independent study. What matters for PhD preparation is not simply how long you were enrolled but what academic and research capabilities you developed.

Before progressing, consider whether you have acquired:

• Appropriate research-methods knowledge
• Experience reviewing scholarly literature
• Independent research experience
• Extended academic-writing ability
• A clearer research specialisation

Your target PhD’s admissions requirements should ultimately determine whether your qualification provides sufficient preparation.

8. Can I apply for a PhD in a different subject from my master’s degree?

Potentially, yes, but the feasibility depends on how closely your existing knowledge and research skills relate to the proposed doctoral field.

Interdisciplinary transitions can work particularly well when you can demonstrate a logical connection between your previous training and your proposed research.

A larger disciplinary change may require additional preparation. For instance, moving from a technical field into qualitative social-science research could require knowledge of new theories, literature, methodologies, and research conventions.

Review the doctoral program’s subject prerequisites and discuss research fit with the relevant department or potential supervisor where appropriate.

9. What should I do if one university requires a master’s and another does not?

Treat each university’s requirements independently.

There is no contradiction simply because two doctoral programs use different admissions models. Universities design doctoral training around their own academic structures, disciplinary expectations, coursework, funding arrangements, and research traditions.

Compare:

• Required qualifications
• Research experience
• Program structure
• Supervisor expectations
• Research-methods training
• Funding
• Program duration
• Career fit

Then decide which program and pathway are best suited to your preparation and goals. Do not select a doctoral program solely because its entry route appears shorter.

10. When should I seek academic editing or research support?

Academic support may be useful when your ideas and research are your own but you need help communicating them more clearly.

For example, a master’s student preparing a dissertation or a PhD researcher developing a research paper may benefit from feedback on language, structure, coherence, academic tone, referencing consistency, or alignment between different manuscript sections.

Researchers remain responsible for their data, methods, interpretations, citations, claims, and final submission. They should also check whether their institution places restrictions on external editing or AI-assisted support.

Where appropriate, Contentxprtz offers academic editing and research-focused editing designed to improve clarity while preserving the researcher’s intellectual ownership.

Conclusion

So, what comes first: a PhD or a master’s?

In the traditional sequence, the master’s comes first and the PhD follows. The master’s usually develops advanced knowledge, specialisation, and research capability, while the PhD represents a higher level of academic research centred on producing an original contribution to knowledge.

But the traditional sequence is not a universal admissions rule.

Some doctoral programs require a relevant master’s. Others allow strong candidates to enter directly from a bachelor’s or honours degree. Some provide substantial research training within the doctoral program itself, while others expect applicants to arrive with advanced research preparation already completed.

Your decision should therefore be based on three questions:

1. What does my target PhD program require?
2. What research preparation do I already have?
3. Would a master’s make me substantially better prepared for the research I want to undertake?

If you have already developed strong research skills and your intended program supports direct doctoral entry, a separate master’s may not be necessary. If you need methodological training, subject specialisation, dissertation experience, or time to develop a clearer research direction, a well-chosen master’s can be an important academic foundation.

Whichever route you choose, approach postgraduate study as more than a sequence of credentials. Focus on developing the expertise, research judgement, academic integrity, and communication skills required to produce rigorous scholarly work.

When your research is complete but the writing needs greater clarity, coherence, or academic polish, appropriately used research paper editing support can help strengthen the communication of your work while preserving your responsibility for its ideas and evidence.
