For many researchers, the first question about a journal is simple: Is it Q1? Quartile labels—Q1 through Q4—have become shorthand for prestige, impact, and academic value. Hiring committees mention them. Grant reviewers look for them. Doctoral regulations sometimes require them. Yet despite their influence, quartiles are widely misunderstood.
A journal’s quartile is not a universal measure of quality. It is a relative ranking within a specific subject category, in a specific database, in a specific year. Treating it as an absolute signal can lead authors to make poor strategic decisions, misunderstand disciplinary variation, or fall into metric traps.
This guide explains what journal quartiles actually measure, how they differ across indexing systems, what they signal—and what they do not—and how authors should use them wisely in 2024–2025.
What Does “Quartile” Actually Mean?
A quartile divides journals within a subject category into four equal groups based on a citation-based metric. If a journal is Q1, it belongs to the top 25% of journals in that category. Q2 includes journals ranked between 25% and 50%, Q3 between 50% and 75%, and Q4 the bottom 25%.
Three important clarifications follow:
- Quartiles are category-specific. A journal can be Q1 in one category and Q3 in another.
- Quartiles are database-specific. Scopus and Web of Science calculate rankings differently.
- Quartiles are updated annually. A journal’s quartile can change from year to year.
In other words, quartiles describe position within a competitive field—not intrinsic quality.
Scopus (SJR) vs Web of Science (JCR): Two Systems, Two Logics
Scopus and SCImago (SJR)
In Scopus, quartiles are commonly derived from the SCImago Journal Rank (SJR). SJR weighs citations by the prestige of the citing journals, meaning citations from highly ranked journals carry more influence than those from lower-ranked ones.
Scopus also reports CiteScore and percentile ranks. Authors often confuse CiteScore percentiles with quartiles, but they are distinct metrics. A high CiteScore does not automatically guarantee Q1 status, especially in highly competitive fields.
Web of Science and Journal Citation Reports (JCR)
Web of Science calculates quartiles primarily using the Journal Impact Factor (JIF) within Journal Citation Reports. Journals are ranked inside specific subject categories, and quartiles are assigned based on position.
A journal indexed in SCIE or SSCI may have an official Impact Factor and quartile ranking. Journals in ESCI may be indexed but lack a formal Impact Factor. Authors should verify whether quartile claims correspond to official JCR listings.
Quartiles vs Other Metrics Authors Confuse Them With
Quartiles are often mistaken for overall journal quality scores. In reality, they are ranking categories based on underlying metrics. Consider the differences:
- Impact Factor measures average citations per article over a specific period.
- CiteScore calculates average citations over a four-year window in Scopus.
- h-index reflects cumulative citation performance.
- SNIP adjusts for field citation practices.
- Altmetrics measure online attention rather than scholarly citations.
Each metric answers a different question. Quartiles summarize relative position—not methodological rigor, peer review quality, or editorial transparency.
Category Effects: Why Context Matters
Fields vary dramatically in citation density. Biomedical sciences generate far more citations per article than classical studies or philosophy. Therefore, a Q1 journal in mathematics may have a lower Impact Factor than a Q3 journal in oncology.
Some journals are listed in multiple categories. It is entirely possible for a journal to be Q1 in a narrow interdisciplinary category but Q3 in a broader one. Authors should check the exact category relevant to their field.
In 2024–2025, interdisciplinary research has increased. As a result, category alignment has become even more important. Submitting solely based on quartile without checking scope alignment increases desk rejection risk.
What Quartiles Actually Signal
Quartiles can signal several things:
- Relative citation influence within a field
- Competitive positioning among peer journals
- Visibility within major indexing ecosystems
- Institutional recognition in evaluation systems
However, they do not guarantee high editorial standards, efficient review processes, or ethical practices. High-quartile journals have experienced retractions and integrity controversies. Quartile status does not immunize against editorial failure.
Using Quartiles Strategically as an Author
Authors should integrate quartile information into a broader decision framework.
Career Advancement Goals
In institutions where Q1 publications are formally required for promotion or funding, quartile becomes strategically important. In such cases, targeting a well-aligned Q1 journal within your precise subfield increases acceptance probability compared to aiming at a prestigious but poorly matched outlet.
Speed and Practical Impact
If timely publication is critical—such as for grant deadlines or policy impact—mid-quartile journals with clear editorial timelines may be more appropriate than high-rejection Q1 outlets.
Audience Fit
A Q2 journal read widely by your intended academic audience may yield more citations than a Q1 journal in a loosely related category.
Predatory Journals and Fake Quartiles
Increased emphasis on quartiles has produced fraudulent claims. Some journals advertise fake “Global Impact Factors” or fabricated Q1 labels. These are not recognized by Scopus or Web of Science.
To verify legitimacy:
- Check the official Scopus Sources list.
- Consult Journal Citation Reports for JCR quartiles.
- Verify SJR ranking directly on SCImago.
- Review the editorial board and peer review transparency.
A legitimate journal will never rely solely on self-declared metrics.
Expanded Analytical Comparison
| Scenario | Quartile Signal | Main Risk | What to Check Next | Strategic Advice |
|---|---|---|---|---|
| Promotion requires Q1 | High prestige weight | Scope mismatch | Category ranking and acceptance rate | Choose narrow-fit Q1 over broad high-impact journal |
| Interdisciplinary research | Variable across categories | Misaligned audience | All category listings | Prioritize audience over highest quartile |
| Fast publication needed | Limited relevance | Predatory trap | Peer review transparency | Prefer reputable Q2–Q3 with clear timelines |
| Grant evaluation | Metric-sensitive review | Overemphasis on ranking | Database verification | Balance quartile with journal reputation |
| Early-career visibility | Symbolic credibility | High rejection probability | Desk reject statistics | Assess probability realistically |
Common Misconceptions
Myth: Q1 means guaranteed high quality.
Reality: It indicates top 25% position within a category.
Myth: Publishing in Q4 is worthless.
Reality: Q4 journals can still be reputable within specialized or emerging fields.
Myth: Impact Factor equals quartile.
Reality: Quartile reflects ranking relative to others, not raw citation averages.
Conclusion
Journal quartiles provide useful contextual information. They signal relative citation standing within a defined category. They help institutions standardize evaluation. They offer authors a rough map of disciplinary hierarchy.
But quartiles are not a proxy for article quality, peer review rigor, or editorial ethics. They are one metric among many. Wise authors in 2025 treat quartiles as part of a broader strategic evaluation that includes scope alignment, editorial transparency, review timelines, and research audience.
The most successful publication strategy is not simply aiming for Q1. It is aligning your strongest research with the journal where it fits intellectually, methodologically, and strategically.

That was the central question in the earlier phase of the energy transition, when the main challenge was proving that clean power could scale. Today, that point is largely settled. Renewable generation is expanding, […]
Impact Factor vs. CiteScore: Key Differences Explained
Journal metrics are often treated as quick shortcuts. A researcher checks a journal profile, sees an Impact Factor or a CiteScore value, and assumes the number tells the whole story. In practice, that is rarely true. These metrics can be useful, but only when readers understand what they measure, where the data comes from, and […]
Writing a Persuasive Cover Letter to Journal Editors
A cover letter to a journal editor is easy to underestimate. Many authors treat it as a routine formality, something to complete quickly because the real work is in the manuscript itself. That assumption often leads to flat, generic letters that add little value to the submission. A stronger approach starts with a different understanding. […]
