Evaluating Sources (2:16)

The CRAAP Test

The CRAAP Test is a tool you can use to evaluate potential sources.

Currency: The timeliness of the information.

  • When was the information created? (A publication or posting date)
  • Has the information been revised/updated?
  • Is the information out-of-date for your topic?
  • Are the links still working?

Relevance: The importance of the information for your needs.

  • Does the information relate to your topic?
  • Who is the intended audience?
  • Is the information presented at the right level? (not too elementary or too advanced)
  • How does it compare to other sources available to you?

Authority: The source of the information

  • Who is the author?
  • Who is the publisher/sponsor?
  • Are the author's credentials and/or organizational affiliations given?
  • What are the credentials and/or affiliations?
  • What qualifies the author to write on the topic?
  • Is there contact information? (a publisher or an email address)

Accuracy: The reliability, truthfulness, and correctness of the information

  • Where does the information come from?
  • Is there evidence used to support the information?
  • Has the information been reviewed/refereed?
  • Can you verify the information from another source or from personal knowledge?
  • Does the tone of the writing seem biased or free of emotion?
  • Are there spelling, grammar, or other errors?

Purpose: The reason the information exists

  • Why was this written/created? (to inform? teach? sell? entertain? persuade?)
  • Do the authors/sponsors make their purpose clear?
  • Is the information fact. opinion, or propoganda?
  • Does the point of view appear objective and impartial?
  • What sources of bias are present, and does the author mention how they tried to mitigate them?
