The CRAAP test is made up of five categories which each has a series of prompts to ask about your source. As you answer them, you learn about its credibility. The more credible, the better. And the better your source is, the better you will be able to analyze the arguments within.
Currency: the timeliness of the information
Relevance: the importance of the information for your needs
Authority: the source of the information
Accuracy: the reliability, truthfulness, and correctness of the content
Purpose: the reason the information exists
Note: the CRAAP test was developed by librarians at CSU Chico.
