Applying the CRAAP Test

Finding accurate, reliable sources of information online can be a challenge.  As a rule of thumb, some of the best information on the web comes from government agencies, educational institutions, and non-profit organizations.  However, all sources should be carefully evaluated before you use them.  An easy way to remember how to evaluate information is to apply the C.R.A.A.P Test.


  • When was the information published or posted?
  • Has the information been revised or updated?
  • Is the information current or out-of date for your topic?
  • Are the links functional?


  • Does the information relate to your topic or answer your question?
  • Who is the intended audience?
  • Is the information at an appropriate level (i.e. not too elementary or advanced for your needs)?
  • Have you looked at a variety of sources before determining this is one you will use?
  • Would you be comfortable using this source for a research paper?


  • Who is the author/publisher/source/sponsor?
  • What are the author's credentials or organizational affiliations?
  • What are the author's qualifications to write on the topic?
  • Is there contact information, such as a publisher or e-mail address?
  • Does the URL reveal anything about the author or source?
  •  For example: .com (commercial), .edu (educational), .gov (government), .org (nonprofit organization)?


  • Where does the information come from?
  • Is the information supported by evidence?
  • Has the information been reviewed or refereed?
  • Can you verify any of the information in another source or from personal knowledge?
  • Are there spelling, grammar, or other typographical errors?


  • What is the purpose of the information? to inform? teach? sell? entertain? persuade?
  • Do the authors/sponsors make their intentions or purpose clear?
  • Is the information fact? opinion? propaganda?
  • Does the point of view appear objective and impartial?
  • Are there political, ideological, cultural, religious, institutional, or personal biases?

Web Site Evaluation

While it may seem easier to do a web search for information rather than use a library database, you need to critically evaluate web sites. While there are numerous web pages that describe how to evaluate a web site, in addition to the C.R.A.A.P Test, here are a few other websites that you may find useful:
