The CRAAP Test
Developed by librarians at California State University-Chico, the CRAAP Test (Currency, Relevance, Authority, Accuracy, and Purpose) is a handy checklist to use when evaluating online resources. The test provides a list of questions to ask yourself when deciding whether or not a source is reliable and credible enough to believe or share.
Note: The CRAAP test was designed to help students evaluate any website for academic use. The test is still a powerful tool for evaluating news sites, but you might need to alter some of the steps to better suit your needs.
