Peer Review Process

Learn about scholarly journals and the peer review process
According to the International Committee of Medical Journal Editors, "peer review is the critical assessment of manuscripts submitted to journals by experts who are usually not part of the editorial staff. Because unbiased, independent, critical assessment is an intrinsic part of all scholarly work, including scientific research, peer review is an important extension of the scientific process" (ICMJE, 2017). When searching the literature, be sure to choose peer-reviewed publications. The peer review process gives articles more authority. Keep in mind that not every item indexed in a peer-reviewed journal is an article (e.g. book reviews, letters).

The Peer Review Process

The peer review process can be broadly summarized below, although these steps may vary slightly between journals.

  1. Submission of Paper - The corresponding or submitting author submits the paper to the journal
  2. Editorial Assessment - The journal checks the paper’s composition and arrangement against the journal’s Author Guidelines to make sure it includes the required sections and stylization. The quality of the paper is not assessed at this point.
  3. Appraisal by the Editor-in-Chief - The EIC checks that the paper is appropriate for the journal and is sufficiently original and interesting. If not, the paper may be rejected without being reviewed any further.
  4. Editor-in-Chief assigns an Associate Editor - Some journals have Associate Editors who handle the peer review. If they do, they would be assigned at this stage.
  5. Invitation to Reviewers - The editor sends invitations to individuals he or she believes would be appropriate reviewers. As responses are received, further invitations are issued, if necessary, until the required number of acceptances is obtained.
  6. Response to Invitations - Potential reviewers consider the invitation against their own expertise, conflicts of interest and availability. They then accept or decline. If possible, when declining, they might also suggest alternative reviewers.
  7. Review is Conducted - The reviewer sets time aside to read the paper several times. The first read is used to form an initial impression of the work. If major problems are found at this stage, the reviewer may feel comfortable rejecting the paper without further work. Otherwise they will read the paper several more times, taking notes so as to build a detailed point-by-point review. The review is then submitted to the journal, with a recommendation to accept or reject it – or else with a request for revision (usually flagged as either major or minor) before it is reconsidered.
  8. Journal Evaluates the Review - The editor considers all the returned reviews before making an overall decision. If the reviews differ widely, the editor may invite an additional reviewer so as to get an extra opinion before making a decision.
  9. The Decision - The editor sends a decision to the author including any relevant reviewer comments. Whether the comments are anonymous or not will depend on the type of peer review that the journal operates.
  10. The Next Steps - If accepted, the paper is sent to production. If the article is rejected or sent back for either major or minor revision, the handling editor should include constructive comments from the reviewers to help the author improve the article At this point, reviewers should also be sent an email or letter letting them know the outcome of their review. If the paper was sent back for revision, the reviewers should expect to receive a new version, unless they have opted out of further participation. However, where only minor changes were requested this follow-up review might be done by the handling editor.
