Peer-reviewed journals contain scholarly articles that have been reviewed by a panel of scholars or experts in a particular discipline before publication. When you are using the CRAAP Test to evaluate resources, this helps verify accuracy.

What does it mean when an article is peer reviewed?

• First, scientists do some science. 

• Then, they write up their findings.

• They submit their article to a journal for peer review.

• The journal sends the article to other experts in the same field to review before publishing.

• If the article stands up to peer review (review by the scientists' peers) it can be published in the journal.

• Other researchers can now use that research to do their own research.
