PLOS is a non-profit organization on a mission to drive open science forward with measurable, meaningful change in research publishing, policy, and practice.

Building on a strong legacy of pioneering innovation, PLOS continues to be a catalyst, reimagining models to meet open science principles, removing barriers and promoting inclusion in knowledge creation and sharing, and publishing research outputs that enable everyone to learn from, reuse and build upon scientific knowledge.

We believe in a better future where science is open to all, for all.

About Our Reviewer Resources

The PLOS Peer Review Center is a collection of free training and resources for peer reviewers of PLOS journals—and for the peer review community at large, drawn from research and interviews with staff editors, editorial board members, and experienced reviewers.

We know that peer review can be tricky and is something that is rarely taught. We hope the resources we offer will help you feel more prepared and more confident the next time you do a review.

We also know that peer review is hard work and takes time. We hope the resources here make your work a little easier or go a little faster.

Already have a lot of experience reviewing? Consider this a helpful refresher. Take a look around, and you might find something new.

Some caveats

The guides here are not meant to be substitutes for any instructions you’re asked to follow for a specific journal. Always check the journal-specific guidelines for reviewers when you accept a review assignment.

If you are reviewing a manuscript for PLOS and have specific questions about your assignment, please email the journal directly. Unfortunately, we won’t be able to assist you here. Please email the journal directly.

We’ve designed the Reviewer Center with you, the reviewer, in mind. Let us know what you think, so we can improve upon the information provided here. Thank you for being part of our community!
