Peer review involves subjecting the author's scholarly work and research to the scrutiny of other experts in the same field to check its validity and evaluate its suitability for publication. A peer review helps the publisher decide whether a work should be accepted.

In science, peer review typically works something like this: A group of scientists completes a study and writes it up in the form of an article. ... Those reviewers provide feedback on the article and tell the editor whether or not they think the study is of high enough quality to be published.

Peer review means that a board of scholarly reviewers in the subject area of the journal, review materials they publish for quality of research and adherence to editorial standards of the journal, before articles are accepted for publication.

The three most common types of peer review are: Single blind. Double blind. Open review.
