Peer-reviewed articles are read by subject experts ("peers" of the author) before they are published in a journal. The experts look for mistakes, suggest the author make changes to the articles, and may even recommend that an article not be published at all. The purpose of peer review is to ensure that the highest quality articles are published.
Sometimes this review process is called "refereeing." A peer-reviewed article and a refereed article are usually considered to be the same thing. |
