The CRAAP Test is a valuable tool for evaluating your sources.
If you're looking for information in an online search engine like Google or Yahoo, you often find too much information and not all of it is useful (and some of it is just bad). The CRAAP Test involves a series of questions designed to help students evaluate online information to determine if they should use the information for class projects, papers, or presentations.
