Short answer: Clarivate currently describes a single set of 28 criteria for journal evaluation: 24 quality criteria focused on editorial rigor and best practice, plus four impact criteria used to identify the most impactful journals in their fields.
The detailed criteria cover areas such as journal information, peer-review policy, editorial information, publishing regularity, content relevance, citation activity, author and editorial-board characteristics, and other quality or impact indicators.
The criteria and process can change, so publishers should rely on Clarivate’s current official documentation rather than an old third-party checklist.
A consultant can help a publisher understand public criteria, but Clarivate’s in-house editorial team makes the selection decision.
