What is a Q1 Journal?
A Q1 journal is a highly prestigious scholarly publication ranked in the top 25% of its specific subject category based on citation impact metrics. It represents the highest tier of prestige, influence, and quality within a particular academic discipline, making it a primary target for ambitious researchers worldwide.
The step most authors miss
Doing CRediT right? Don’t stop at the statement.
A CRediT statement credits you inside one paper. The recognition CRediT was built for happens when those roles are tied to you, persistently. Sign in with your ORCID — free — and claim your CRediT contributions on casrai.org, the home of the standard. They become a verified, portable part of your identity, not a line that disappears into one PDF.
Free: claim your contributions, then export a journal-ready CRediT statement, schema.org structured data, JATS XML, CSV or BibTeX — and preview your public profile. A membership publishes that profile publicly and verifies the journals you serve.
How Journal Quartiles are Calculated
To determine a journal's quartile, a database ranks all journals within a specific subject category from highest to lowest according to their citation metric (such as CiteScore or Journal Impact Factor). This ranked list is then divided into four equal parts. The top 25% of journals are designated as Q1, the next 25% as Q2, followed by Q3, and the bottom 25% as Q4. Because citation behaviors differ widely between fields, these calculations are discipline-specific; a journal is only compared to others in its own field.
The Significance of Q1 Publications in Academia
In many universities and research institutes worldwide, publishing in Q1 journals is a critical metric for career advancement. It is heavily weighted in decisions regarding academic promotion, tenure, and hiring. Furthermore, national funding bodies and research assessment exercises (such as the Research Excellence Framework in the UK) often track Q1 publications as a key indicator of institutional research excellence and impact.
How to Identify Q1 Journals in Your Field
Researchers can identify Q1 journals using database directories. For Web of Science, the Journal Citation Reports (JCR) portal provides official JIF-based quartiles. For Scopus, the SCImago Journal & Country Rank (SJR) or the Scopus Source list displays CiteScore-based quartiles. Since a journal can be indexed in multiple categories, it is possible for a publication to be ranked Q1 in one subject area and Q2 in another.
Key facts
At a glance
- Q1 denotes the top 25% of journals in a specific subject category based on citation metrics.
- A journal's quartile can vary between different databases (e.g., Scopus CiteScore vs. Web of Science JIF).
- Quartiles are relative to the specific field, meaning a humanities journal is not compared directly to a medical journal.
- A journal can occupy different quartiles in different categories if it is multi-disciplinary.
- Journal rankings and quartiles are updated annually, which can cause journals to move between tiers.
Common misconceptions
What people often get wrong
Often heard: A Q1 journal is always superior to a Q2 journal for all types of research.
Actually: While Q1 journals generally have higher citation metrics, a Q2 journal might be more specialised, relevant, or suitable for a specific niche study.
Often heard: Every article published in a Q1 journal will receive a high number of citations.
Actually: Journal impact metrics reflect the average citation rate of the journal; individual articles within a Q1 journal can still receive few or no citations.
Often heard: Journal quartiles are static and never change.
Actually: Rankings are recalculated every year based on new citation data, meaning a journal can rise to Q1 or drop to Q2.
