CRAPP is an acronym used by researchers to determine the reliability of sources. It consists of the following factors:
Currency - timeliness of the information
- Why was this information published? Has the research been revised or updated? Does your topic require current information or historical?
Relevance - importance of the information for your topic
- Does the information relate to your topic or help to answer your question? Who is the intended audience? Have you looked at other sources to determine this one is best?
Authority - source of the information
- Who is the author, publisher, and source? What are their credentials or affiliations? Is the author qualified to speak on the topic?
Accuracy - reliability, truthfulness, and correctness of the content
- Where does the information come from? Is it supported by evidence? Is it peer reviewed? Can you verify the information in another source? Does the language seem unbiased?
Purpose - reason the information exists
- What is the purpose of this information (to inform, teach, entertain, persuade)? Does the author make their intention clear? Is it factual or opinion based? Does the point of view seem objective or is there bias?
