Start Your Research

Evaluate your results

Evaluate your sourcesNot all information is created equal!

Just being in print or available via the Internet doesn't guarantee that something is accurate or good research. When searching the web, it's important to critically evaluate your search results:

  • Look for articles published in scholarly journals 
    or sources that require certain standards or criteria be met before publication.

  • Look for materials at Web sites that focus on scholarly resources 
    (e.g. Google Scholar)

  • Compare several opinions 
    by scholars in your topic field is another way to verify or evaluate your sources.

  • Consult your instructor.

CRAAP Test: Tips on Evaluating Sources

Some things to consider in evaluating the quality of research sources:

Currency: the timeliness of the information

  • How recent is the information?
  • Can you locate a date when the page(s) were written/created/updated?
  • Based in your topic, is it current enough?

Reliability: importance of the information

  • What kind of information is included in the website?
  • Is the content primarily fact, or opinion? Is the information balanced, or biased?
  • Does the author provide references for quotations and data?
  • If there are links, do they work?

Authority: the source of the information

  • Can you determine who the author/creator is? is there a way to contact them?
  • What are their credentials (education, affiliation, experience, etc.)?
  • Who is the publisher or sponsor of the site? Are they reputable?

Accuracy: the reliability, truthfulness and correctness of the information

  • Is it accurate? Is it supported by evidence?
  • Is the information balanced or biased?
  • Was it peer-reviewed?
  • Can you verify the information from another reliable source?
  • Are there spelling, grammar, or typographical errors?
  • Can you determine who the author/creator is? is there a way to contact them?

Purpose: the reason the information exists

  • What's the intent of the website (to persuade, to sell you something, etc.)?
  • What is the domain (.edu, .org, .com, etc.)? 
  • Are there ads on the website?
  • How do they relate to the topic being covered (e.g., an ad for ammunition next to an article about firearms legislation)?
  • Is the author presenting fact, or opinion? Who might benefit from a reader believing this website?
  • Based on the writing style, who is the intended audience?

The CRAAP Test was developed by librarians at California State University, Chico.

  • They use scholarly or technical language and tend to be longer and include full citations for sources.
  • Peer reviewed or refereed which means articles are reviewed by other scholars before being published.


popular magazinesPopular Magazines and Newspapers articles
