After an editor receives a manuscript, their first step is to check that the manuscript meets the journal’s rules for content and format. If it does, then the editor moves to the next step, which is peer review. The editor will send the manuscript to two or more experts in the field to get their opinion. The experts – called peer reviewers – will then prepare a report that assesses the manuscript, and return it to the editor. After reading the peer reviewer's report, the editor will decide to do one of three things: reject the manuscript, accept the manuscript, or ask the authors to revise and resubmit the manuscript after responding to the peer reviewers’ feedback. If the authors resubmit the manuscript, editors will sometimes ask the same peer reviewers to look over the manuscript again to see if their concerns have been addressed. This is called re-review.
