How to Evaluate Sources

The CRAP Test* provides valid criteria and a memorable mnemonic. Think about these criteria when evaluating claims.

Currency - timeliness

Reliability - accuracy

 Authority - the source

Purpose - the reason

* The CRAP Test was developed by librarian Molly Beestrum, Dominican University. Another version of the CRAP Test, the CRAAP Test, can be found on the Duquesne University Library website.
