According to the Committee on Publication Ethics (COPE), "Peer review is the process by which a piece of scientific research is assessed by others - a researcher's fellow peers - who are suitable qualified and able to judge the piece of work under review in terms of novelty, soundness and significance."
Peer review helps to ensure that high-quality, accurate, and ethical work is being published. It is an integral part of the research process and a staple in the academic research community. Is is often predatory publishers and journals that exploit and deny the proper peer review process. Students can also benefit from learning the peer review process. In the book Student-Led Peer Review: A Practical Guide to Implementation Across Disciplines and Modalities, the authors state that "student-led peer review is a powerful tool for learning. It helps students master academic content, improve the quality of their work, and develop self-evaluative, interpersonal, and practical workplace skills" (Lowe et. al, 2022).
Once a manuscript is submitted to a journal for publication, an editor or editorial team collaborates with a group of peer reviewers to evaluate it. Usually the editor(s) function as the initial screening layer, through which manuscripts that are deemed within scope and of high quality are passed on to peer reviewers for commenting and review. The peer reviewers then read the manuscript, making notes or commenting as they see fit. Each journal has a set of guidelines for peer reviewers to follow that can be extensive or simple. Following the review, the annotated manuscript is then returned to the author, along with the decision of the peer reviewer. Decisions can fall under five major categories:
While the editor(s) ultimately make the final call on accepting or rejecting a manuscript, reviewer recommendations play a major role in that decision. If you are submitting a manuscript to be published, it is necessary to take the annotations and recommendations of your peer reviewers seriously in order to ensure publication.
Even though peer review is still considered integral to the research process, it does not come without its own set of issues. Below are just a few:
Despite these issues with peer review, professionals in the field remain compassionate and hopeful. An excerpt taken from a blog post on The Scholarly Kitchen quotes Katie Duffy, Senior Director of Publications at the American Society for Bone and Mineral Research, stating "We also need to recognize that the pressure on our authors and referees to work quickly and produce more and more can sometimes invite shortcuts or lapses in judgement. Peer reviewer education and strong support from editorial teams is critical to ensuring that right balance between quality and speed" (We Asked the Community: Is Research Integrity Possible without Peer Review?, 2022).
