Understanding Journal Quartiles Before You Choose Where to Submit
If you are asking what is the difference between a Q1 Q2 Q3 and Q4 journal, the essential point is that Q1–Q4 are relative journal-ranking bands, not four universal quality certificates. A Q1 journal sits in the highest quartile of a defined subject category for a particular metric and year; Q2, Q3 and Q4 represent progressively lower quartile bands in that same comparison. The label can be useful because it shows where a journal stands among peers in its field, but it becomes misleading when people omit the database, subject category, metric or year.
This matters because researchers often encounter several versions of “quartile.” In Scopus, CiteScore Percentile is used to show a source’s relative standing within a subject field, with quartile bands derived from those percentiles. In Clarivate’s Journal Citation Reports (JCR), quartile ranks are also category-based, but the system uses JCR category rankings and must account for tied rank positions. Consequently, a journal described as Q1 in Scopus is not automatically Q1 in JCR, and the same title can occupy different quartiles in different subject categories.
For a PhD scholar, early-career researcher or first-time journal author, this distinction is practical rather than merely technical. Some universities, funding bodies and promotion systems ask authors to report journal quartiles. Some supervisors encourage students to target Q1 or Q2 journals. Publishers may display a journal’s best category performance, while institutional forms may require the quartile that applies to a specific discipline or publication year. If you do not record the source and year, you can easily compare unlike metrics or repeat an outdated claim.
This guide explains the meaning of Q1, Q2, Q3 and Q4, compares Scopus and JCR interpretations, shows why quartiles change, and provides a responsible journal-selection workflow. It also explains when quartile matters and when manuscript fit matters more. If you already have a target journal, Contentxprtz can provide manuscript assessment or academic editing services to improve readiness without promising publication outcomes.
Quick Answer: What Is the Difference Between a Q1 Q2 Q3 and Q4 Journal?
Q1 is the highest quartile, followed by Q2, Q3 and Q4. In Scopus CiteScore quartiles, Q1 covers the 99th–75th percentile band, Q2 the 74th–50th, Q3 the 49th–25th and Q4 the 24th–0 percentile band within a subject field.
In JCR, quartile ranks are also category-based, but tied journal ranks can make the groups uneven. The same journal may therefore have different quartiles across categories, databases or years.
For submission decisions, use quartile as one signal alongside scope, audience, indexing, editorial quality, peer-review model, fees and manuscript fit.
Key Takeaways
- Q1 means the highest quartile within a defined subject category; Q4 is the lowest quartile.
- Quartiles are relative rankings, so they depend on the comparison group and year.
- Scopus and JCR can assign different quartiles because their databases, categories and metrics differ.
- A journal can hold different quartiles in different subject categories at the same time.
- Quartile is not the same thing as peer-review quality, acceptance probability or journal fit.
- Always verify quartile from an official source and record the metric, category and year.
- Choose a journal by fit first, then use quartile and other metrics as supporting evidence.

Methodology and Academic Sources
This guide uses official information from Scopus/Elsevier and Clarivate to explain quartile logic. Scopus states that CiteScore quartiles group serial titles according to their position in subject categories and defines Q1 through Q4 using percentile bands. Clarivate’s JCR materials describe category rankings and note that tied ranks can affect quartile distributions.
For current verification, consult Scopus CiteScore metric guidance, Elsevier’s CiteScore overview, Clarivate’s Journal Citation Reports overview, and Clarivate’s explanation of how ties affect JIF quartile distributions. Researchers should also follow relevant institutional assessment rules, because a university may specify a particular database or reference year.
What Q1, Q2, Q3 and Q4 Mean in Academic Publishing
A quartile divides a ranked set into four bands. Applied to journals, the ranking is calculated within a subject category rather than across all scholarly journals in the world. The purpose is to give researchers a field-relative view, because citation behavior differs strongly across disciplines.
Q1 Journal
Highest quartile in the specified category. Often described as the top 25% band, subject to the ranking system’s treatment of ties and category size.
Q2 Journal
Second quartile. Strong relative standing, but below Q1 within the stated category and metric.
Q3 Journal
Third quartile. A middle-to-lower relative ranking within the category, not a statement that the journal lacks peer review or legitimacy.
Q4 Journal
Lowest quartile in the category. It may still be indexed and legitimate, although institutional policies may value it differently.
Quartiles are therefore contextual labels. A Q1 journal in education is not ranked against a Q1 journal in cardiology. Each is compared with journals assigned to its own subject category. Similarly, “Q1” does not tell you the journal’s acceptance rate, editorial turnaround time, open-access fee, data-sharing policy or suitability for your topic.
| Quartile | General interpretation | Scopus CiteScore percentile band | What authors should remember |
|---|---|---|---|
| Q1 | Highest quartile | 99th–75th percentile | High relative citation standing does not guarantee manuscript fit or acceptance. |
| Q2 | Second quartile | 74th–50th percentile | Can be an excellent target when scope and readership align strongly. |
| Q3 | Third quartile | 49th–25th percentile | Evaluate indexing, editorial quality and institutional requirements. |
| Q4 | Lowest quartile | 24th–0 percentile | Lower relative ranking does not by itself prove poor or predatory practice. |
Scopus Q1–Q4 Versus JCR Q1–Q4: Why the Labels Can Differ
Scopus and JCR quartiles are not interchangeable. Scopus uses its own indexed source set, subject classifications and CiteScore metrics. JCR uses Web of Science data and JCR category rankings. Because the journal universe and calculation systems differ, the same title may receive different quartiles.
Scopus CiteScore Quartiles
Scopus calculates CiteScore Percentile by ranking serial titles within a subject field. Its official guidance groups titles into Q1 (99th–75th percentiles), Q2 (74th–50th), Q3 (49th–25th) and Q4 (24th–0). A title can receive a different percentile and quartile in every subject area where Scopus categorizes it.
Journal Citation Reports Quartiles
JCR presents journal rankings within categories using its own metrics and rank structure. Clarivate has explained that quartiles are based on rank positions and that journals tied at the same rank cannot be split between quartiles. That means the groups may contain more or fewer than exactly 25% of journals when ties occur.
| Factor | Scopus context | JCR context | Researcher implication |
|---|---|---|---|
| Journal set | Scopus-indexed sources | Journals included in JCR/Web of Science context | Different comparison populations can change rank. |
| Primary ranking context | CiteScore percentile and related source metrics | JCR category rankings and journal metrics | Do not translate one database’s quartile into another. |
| Subject categories | Scopus subject classification | JCR categories | Category boundaries and peer groups can differ. |
| Ties | Percentile logic handles titles with the same CiteScore value | Tied rank positions can alter quartile group sizes | “Top 25%” is a useful shorthand, not always a literal equal split. |
| Year | Annual CiteScore metrics | Annual JCR release | Always state the year used. |
When a university form asks for “Q1/Q2,” check the policy language. It may specifically mean Scopus CiteScore quartile, JCR quartile, SJR quartile or another institutional definition. The safest approach is to provide the exact source rather than assuming that any Q1 label will satisfy the requirement.
Step-by-Step: How to Check Whether a Journal Is Q1, Q2, Q3 or Q4
- Identify the required database. Check whether your institution, supervisor, funding scheme or promotion policy specifies Scopus, JCR/Web of Science, SJR or another source.
- Search by exact title or ISSN. Journal names can be similar, change over time or have regional editions. ISSN verification reduces confusion.
- Select the correct year. Quartiles change. Use the year required by the policy or the publication year if that is the stated rule.
- Check every relevant category. A multidisciplinary journal may be Q1 in one category and Q2 in another.
- Record the metric and percentile or rank. Saving only “Q1” removes context. Record the supporting CiteScore percentile or JCR rank where available.
- Verify indexing status separately. A quartile screenshot does not replace checking whether the journal is currently covered by the database.
- Save evidence appropriately. Keep the source page, access date or institutional report required for assessment.
Common Mistakes When Interpreting Journal Quartiles
The most common error is treating quartile as an absolute quality grade. Quartile reflects relative citation positioning within a defined peer group; it does not directly measure every component of editorial quality or research relevance.
| Mistake | Why it causes confusion | Better practice |
|---|---|---|
| Writing “Q1 journal” with no year | Quartiles can change annually. | State the ranking year. |
| Ignoring subject category | A journal can have multiple quartiles. | State the category relevant to your paper. |
| Mixing Scopus and JCR | They use different datasets and ranking systems. | Name the database and metric. |
| Assuming Q1 guarantees acceptance | Editorial decisions depend on scope, novelty, methods and peer review. | Assess manuscript-journal fit and readiness. |
| Assuming Q4 means predatory | Low relative citation ranking is not a publishing-ethics diagnosis. | Check indexing, editorial transparency and ethics independently. |
| Choosing only by prestige | A poor scope match wastes time and can reduce visibility with the right audience. | Prioritize relevance, then use quartile as supporting context. |
Targeting a Q1 or Q2 Journal?
Strengthen language, structure, formatting and journal alignment before submission without compromising authorship.
How to Choose Between Q1, Q2, Q3 and Q4 Journals for Your Manuscript
Start with scope and readership, not quartile. Read the journal’s aims and scope, then inspect recent papers from the last one to two years. If your topic, methods and article type rarely appear, a high quartile will not compensate for weak alignment.
1. Confirm Scholarly Fit
Ask whether the journal publishes research questions like yours, whether your methodology is familiar to its audience, and whether the contribution matches the journal’s level of novelty. Compare your manuscript with recent papers for study scale, analytical depth, theoretical contribution and presentation style.
2. Verify Indexing and Ranking
Check the official source record rather than a publisher badge alone. Record the category and year. If your institution recognizes only certain indexing services, use those rules before investing time in formatting or submission.
3. Review Editorial and Ethical Signals
Look for a transparent editorial board, peer-review process, publication-ethics policy, correction and retraction procedures, conflict-of-interest policy and clear author instructions. Quartile does not replace these checks. The Committee on Publication Ethics guidance provides useful principles for responsible publishing practice.
4. Understand Costs and Access
Determine whether the journal is subscription, hybrid or fully open access, and verify article processing charges on the publisher’s official site. Check waiver policies if relevant. A Q1 journal can be free to authors or expensive; a Q3 journal can also be free or fee-based. Quartile does not determine price.
5. Assess Manuscript Readiness
High-ranking journals often receive large submission volumes and may screen aggressively for fit, novelty and presentation quality. Before submission, tighten the title and abstract, align the introduction with the research gap, ensure methods are reproducible, present results cleanly, connect the discussion to evidence, and verify every reference. Professional journal publication support can be useful when you need structured pre-submission review, but editorial decisions remain independent.
Responsible Use of Journal Metrics and Author Responsibility
Journal metrics should inform decisions, not replace expert judgment. A quartile is a journal-level indicator, while the quality of an individual research article depends on its question, methods, data, analysis, transparency and contribution. Researchers should avoid implying that every paper in a Q1 journal is superior to every paper in a Q2 or Q3 journal.
Responsible assessment also means resisting metric manipulation. Authors should not add irrelevant citations to raise a journal’s metric, choose journals solely to game institutional scoring, or misrepresent a journal’s best category as if it applies universally. When reporting publications in a CV, grant application or promotion file, follow the institution’s definition and provide verifiable data.
Ethical academic editing has a separate role. It can improve language, structure, formatting and compliance with author instructions, but it should not fabricate data, invent citations, alter results to fit a target journal or promise acceptance. Authors remain responsible for the research and final submission.
Practical Examples: How Quartile Decisions Work
A PhD Scholar Sees Two Quartiles for the Same Journal
Situation: A journal appears as Q1 in one subject category and Q2 in another.
Common confusion: The scholar thinks one database entry must be wrong.
Correct approach: Both can be valid because quartiles are category-specific. The scholar records the category most relevant to the thesis field and the year required by the university.
Ethical support: An editor helps align the manuscript with that journal’s scope and instructions without exaggerating the quartile claim.
A Researcher Chooses Q1 but Ignores Scope
Situation: A technically sound paper is sent to a prestigious Q1 journal outside its core topic.
Common confusion: The author assumes high quality alone should secure peer review.
Correct approach: After desk rejection, the author compares recent articles and identifies a Q2 journal with much stronger topic alignment and the right readership.
Ethical support: Manuscript assessment focuses on positioning, abstract clarity and journal fit rather than promising a higher-status outcome.
An Early-Career Author Finds an Old “Q1 List”
Situation: A search result shows a PDF claiming the target journal is Q1.
Common mistake: The author does not check the list’s year or metric.
Correct approach: The official current source shows the journal has moved to Q2 in the relevant category. The author records the current status and checks institutional rules.
Ethical support: Publication guidance helps verify source information and prepare the paper for an appropriate target.

How Contentxprtz Can Help With Journal Readiness
Contentxprtz supports researchers who have identified a target journal but want a stronger, clearer and more submission-ready manuscript. Relevant assistance may include research-paper editing, manuscript assessment, language polishing, journal-format alignment, reference consistency and reviewer-response support.
For authors targeting selective journals, a useful review asks whether the title and abstract communicate the contribution quickly, whether the introduction establishes a defensible research gap, whether methods are described clearly, whether results answer the stated questions, and whether the discussion avoids overclaiming. The goal is to improve the manuscript on its merits, not to manufacture the appearance of “Q1 quality.”
If you are still comparing targets, publication support can help structure a journal-selection check, while research paper editing can help prepare the final manuscript for the chosen journal’s instructions.

Summary: What Is the Difference Between a Q1 Q2 Q3 and Q4 Journal?
Q1, Q2, Q3 and Q4 are category-relative journal-ranking bands. Q1 is the highest quartile and Q4 the lowest. In Scopus CiteScore quartiles, Q1 corresponds to the 99th–75th percentile band, Q2 to 74th–50th, Q3 to 49th–25th and Q4 to 24th–0. JCR also reports quartiles by category, but tied rank positions can make the bands uneven.
A journal’s quartile can differ by subject category, database and year. For that reason, “Q1 journal” is incomplete unless you specify the ranking source, metric, category and year. Quartile is useful for benchmarking, but it does not guarantee peer-review quality, acceptance, fit or research impact.
For publication decisions, start with the journal’s scope and audience, verify indexing and quartile from an official source, review editorial and ethical policies, understand fees and access conditions, and assess whether your manuscript is genuinely ready for the target.
Questions About Q1, Q2, Q3 and Q4 Journals
These answers cover the questions researchers most often face when interpreting quartiles and choosing a target journal.
What is the difference between a Q1 Q2 Q3 and Q4 journal?
Q1, Q2, Q3 and Q4 describe a journal’s relative position within a subject category for a particular database, metric and year. In a simple four-band interpretation, Q1 is the highest quartile, Q2 the next, Q3 the next, and Q4 the lowest. In Scopus CiteScore quartiles, Q1 corresponds to the 99th–75th percentile band, Q2 to 74th–50th, Q3 to 49th–25th, and Q4 to 24th–0. Journal Citation Reports also reports quartiles by category, but its ranking procedure uses journal rank positions and ties, so the four groups are not always exactly equal in size. A journal can therefore be Q1 in one category and Q2 in another, or change quartile from year to year. Always record the database, metric, subject category and year instead of writing only “Q1 journal.”
Is a Q1 journal always better than a Q2 journal?
A Q1 label indicates a stronger relative citation position within the stated category and metric, but it does not make a journal universally “better” for every paper. A well-matched Q2 journal may be more appropriate if its scope, readership, methods, article type and editorial priorities align closely with your research. Journal choice should consider relevance, editorial standards, indexing, peer-review practice, publication model, fees, timelines and the audience you need to reach. A prestigious but poorly matched Q1 journal may reject a strong manuscript quickly because the topic falls outside its scope. Researchers should therefore treat quartile as one evidence point, not as a substitute for reading recent papers and author guidelines.
Can the same journal be Q1 and Q2 at the same time?
Yes. Journals are often assigned to more than one subject category. Because quartiles are calculated within categories, the same journal can have a Q1 position in one field and a Q2 or Q3 position in another. Scopus explicitly notes that a title receives a CiteScore percentile for each subject area in which it is indexed. Journal Citation Reports also reports category-specific rankings. This is why claims such as “this journal is Q1” should be checked against the exact category, metric and year. For a manuscript, use the category that most closely represents your research context rather than choosing whichever quartile looks strongest.
Are Scopus Q1 journals the same as Web of Science Q1 journals?
Not necessarily. Scopus and Web of Science use different source collections, subject classifications and journal metrics. Scopus commonly presents CiteScore percentiles and quartiles, while Clarivate’s Journal Citation Reports presents category rankings linked to JCR metrics such as the Journal Impact Factor. A journal may be indexed in one system but not the other, or may occupy a different quartile because its comparison group and metric differ. When a university, funder or promotion policy asks for Q1 or Q2 publications, confirm which database and year the policy recognizes before selecting a target journal.
Does Q1 mean a journal has the highest impact factor?
Q1 does not mean “the journal with the highest impact factor.” It means the journal falls in the highest quartile of its category according to the specified ranking method. Several journals can be Q1 in the same category, and a journal’s raw metric value may not be comparable across fields because citation practices differ widely. A journal in mathematics and a journal in molecular biology may have very different citation levels even when both are Q1 in their own categories. Use category-based ranking for relative context and avoid comparing raw impact values across unrelated disciplines without normalization.
How do I check whether a journal is really Q1, Q2, Q3 or Q4?
Use the official database or source page for the year you need. For Scopus, search the source title or ISSN in Scopus Sources and review the CiteScore percentile, quartile and subject category. For Web of Science/JCR, use Journal Citation Reports and inspect the journal’s category rank and quartile for the relevant year. Record the journal title, ISSN, category, metric, quartile and year. Avoid relying on screenshots, social posts or third-party lists that do not state their data year. Quartiles can change annually, so an old Q1 claim may no longer describe the current ranking.
Can a journal move from Q1 to Q2 or from Q3 to Q1?
Yes. Quartiles are relative rankings, so they can change when a journal’s citation performance changes, when other journals improve or decline, when categories are reorganized, when titles enter or leave the comparison set, or when metric methodologies and data are updated. A shift from Q1 to Q2 does not automatically mean that the journal suddenly became poor quality; it means its relative position within the category changed. Researchers evaluating publication records should cite the quartile for the publication year or the year required by their institution, rather than applying today’s quartile retrospectively without checking policy.
Is publishing in a Q4 journal bad for a researcher?
A Q4 ranking signals the lowest quartile within the specified category and metric, but it does not automatically mean the journal is illegitimate or unsuitable. Some niche, regional or newer journals may serve a valuable audience while having lower citation visibility. The more important checks are whether the journal is genuinely indexed as claimed, operates transparent peer review, states editorial and ethics policies, provides clear fees, publishes within a coherent scope and has a credible publisher and editorial board. If your institution requires a particular quartile for assessment, however, that policy becomes an additional practical constraint.
Should I choose a journal only by quartile?
No. Quartile should be part of a broader journal-selection process. Begin with scope and audience: does the journal publish work like yours, and will the right researchers read it? Then check indexing, current quartile and category, article types, recent papers, acceptance or editorial screening information where available, open-access model, article processing charges, licensing, data policies, preprint rules and typical review timelines. Finally, assess whether your manuscript is technically ready for that journal. A well-prepared manuscript targeted to the right journal is a more defensible strategy than chasing the highest quartile without fit.
How can Contentxprtz help with Q1 or Q2 journal submission preparation?
Contentxprtz can support journal readiness through ethical research-paper editing, manuscript assessment, language polishing, formatting, reference checks and publication-support guidance. The editor can help you compare your manuscript with the target journal’s scope and author instructions, improve clarity and structure, and identify presentation issues before submission. The service should not be treated as a promise of acceptance or a way to manipulate research metrics. Authors remain responsible for the research, data, conclusions, citations and final journal choice, while the journal editor and peer reviewers retain independent decision-making authority.
Use Quartiles as Context, Then Choose the Journal That Fits
The practical difference between Q1, Q2, Q3 and Q4 is a journal’s relative position within a subject-category ranking. Q1 indicates the highest quartile, but that label should never be separated from its database, metric, category and year.
Self-service checking is usually enough to verify a journal’s current quartile. Expert support becomes useful when you need help interpreting journal fit, improving manuscript structure and language, aligning with author instructions, or preparing a technically complex paper for submission.
Contentxprtz helps researchers improve clarity, structure, ethics and publication readiness while preserving author responsibility. No editor can guarantee acceptance, and no quartile can replace a strong research question, sound methods, transparent evidence and a journal that reaches the right scholarly audience.
