Digital Literacy

Introduction to Evaluation

As a digitally literate citizen, you will want to have the skills to evaluate information. How do you know if the information you find is credible and reliable? Some universities suggest to use the CRAAP Test to evaluate sources. CRAAP is an acronym for "Currency, Relevance, Authority, Accuracy, and Purpose." The CRAAP Test was developed by Sarah Blakeslee and a group of librarians at the California State University at Chico.
