Extended definition
Qualis CAPES is the journal stratification system maintained by Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) — Brazil’s federal research funding agency — for quadrennial evaluation of stricto sensu graduate programs (master’s and doctoral). In its historical formulation (1998–2018), each of the 49 CAPES evaluation areas had its own independent classification in strata A1, A2, B1-B5, C — generating the phenomenon of the same journal having distinct classifications across different fields. The 2019 reformulation (Comunicado nº 1/2019 and subsequent updates) adopted unified cross-area classification with strata A1, A2, A3, A4, B1, B2, B3, B4, C, grounded in consolidated international metrics — Journal Impact Factor (Web of Science), CiteScore (Scopus), SJR (SCImago Journal Rank), h-index — for each parent area (Health, Exact Sciences, Biological, Humanities, Applied Social Sciences, Linguistics-Letters-Arts, Multidisciplinary). Barata (2016, RBPG) offered influential critical analysis of the old system and its structural limitations; current official documentation is available on the CAPES portal. Qualis directly affects careers: A1/A2 publications count more than B3/B4 in faculty competitions, scholarships, institutional projects.
When it applies
Qualis applies centrally in Brazilian institutional evaluation of stricto sensu graduate programs — CAPES quadrennial assessment, institutional reports, Lattes CVs in faculty competitions. It applies in individual decisions by Brazilian researchers about submission venue: prioritizing high strata is rational practice given the incentive structure. It applies in institutional funding proposals (CNPq, FAPESP) that weight Qualis in team merit criteria. It applies in thesis defenses and faculty competitions — advisors and candidates evaluate publication history by strata. It applies in national university rankings that incorporate scientific production metrics.
When it does not apply
Qualis does not apply in international evaluation systems — outside Brazil, institutions and funders use JIF/CiteScore/SJR directly, or their own rankings (UK REF, German Excellence Strategy). It does not apply as a quality certificate for individual articles: stratum is the journal’s, not the article’s; a low-cited article in A1 is not automatically better than a much-cited one in B2. It does not fully apply as a career metric in all humanities — some humanistic traditions value books and chapters over journal articles. It does not fully apply in fields with strong conference culture (computer science, especially top-tier like NeurIPS, ICML, ACL): Qualis Eventos exists but with lower weight. It does not replace critical reading: stratum is a proxy for average quality, not substantive evaluation.
Applications by field
— Health, biological, and exact sciences: high correlation with international JIF/Scopus; high strata correspond to internationally recognized top-tier journals. — Humanities and applied social sciences: adjustments to include Brazilian regional-network journals (SciELO) with relative editorial weight; tension between international metrics and Portuguese-language production. — Linguistics, Letters, and Arts: methodological challenge in metrics for fields where books are traditionally the main vehicle — a parallel Qualis Livros structure exists. — Multidisciplinary and interdisciplinary: post-2019 unified classification reduced ambiguity about priority evaluation area.
Common pitfalls
The first pitfall is treating Qualis as a universal metric: outside Brazil it is unknown; international researchers judge output by the journal itself, not by Qualis. The second is confusing journal stratum with article quality: an isolated A1 article may be weak; a B2 article may be excellent. The third is optimizing career via Qualis at the expense of research program coherence: publishing in A1 outside expertise produces fragmented output. The fourth is ignoring changes between quadrennia: classification thresholds may change; today’s stratum may be revised. The fifth is treating Qualis as predatory-screening certification: some predatory journals have Qualis stratum in old reviews; cross-checking with COPE membership and modern Beall lists is prudent.
