Evaluating Sources

Regardless of where information comes from, it is always a good idea to evaluate your sources. This will help you select the best sources of information for research and anytime that you are seeking information.

Skimming the Surface

Applying the CRAAP Test

Finding accurate, reliable sources of information on the Internet 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Is the information current or out-of date for your topic?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?
