Peer reviewing is where a research proposal or a report of research is read and commented on by people with similar interests and expertise to those who wrote the proposal or report. Peer reviewers might be members of the public, researchers, or other professionals. Peer review helps to check the quality of a report or research proposal. Members of the public who act as peer reviewers may choose to comment on:
whether the research addresses an important and relevant question
the methods used by researchers
the quality of public involvement in the research.
