Peer Reviewed means " a process by which something proposed (as for research or publication) is evaluated by a group of experts in the appropriate field. " (Credit: Merriam-Webster Collegiate Dictionary).
What does it mean when it says an article has been "peer reviewed?"
Generally, when we are talking about searching for articles that have been "peer-reviewed," "peer review" is the rigorous screening process that academic/scholarly articles go through before they are published in academic/scholarly journals. In academia, "peer review" is normally thought of as the strictest standard of review. To be sure you are getting articles that meet the highest standard for academic/scholarly content, you want to indicate scholarly/academic and peer-reviewed when given the option to specify.
For an article to "pass" the peer review process and actually get published in an academic/scholarly/peer-reviewed journal, it goes to an editorial review board of experts (usually PhD's or others with the highest level degrees in the field), sometimes from around the world, who examine the article carefully for content and structure. If the article involves an original research study, the research question(s), literature review, methodology, results, discussion, references, etc. are all scrutinized to make sure the study was carried out properly and the findings are valid. Often articles are sent from the peer reviewers back to the authors for revisions and corrections before they are published.
