PRE-val is a service that independently validates peer review processes for scholarly journals. It provides a badge that journals can display to signal that a given article has undergone quality peer review. PRE-val aims to increase transparency and trust in peer review by answering whether an article has truly been peer reviewed and providing information about the journal's review process. It was created due to increasing criticism of traditional peer review and problems like predatory publishers. PRE-val supports best practices in peer review to encourage high-quality review.
