Evaluating information

Critically evaluating information that you find to use for your assignments is essential for academic success, as well as a useful life skill.

The CRAAP Test was developed by Sarah Blakeslee of California State University as an easy to remember acronym to help judge if a source is worth using.


  • Is it up-to-date? Does it need to be?
  • When was it published, or last updated (web page)?


  • Is the information useful and does it support your work?
  • Does it cover your topic in enough depth and scope? e.g. Geography i.e. Australian? International?
  • Does it meet your needs? - i.e. is it peer-reviewed if you are required to use a peer-reviewed journal?


  • Who is the author? Are they known in their field? Are they associated with reputable organisations? e.g. a university or official body
  • For a web page:
    • is the author noted or is the organisation well known? e.g. government agency?
    • do the links work? Does the site look well maintained?
  • Is there advertising alongside the information?


  • Is it supported by reliable facts or statistics? References?
  • Look at the URL for web pages. Is the site commercial (.com), government (.gov) or educational (.edu)?


  • Why was it written? Is it to inform, teach, sell entertain or persuade?
    • Is the work fact, opinion or propaganda?
    • Does it contain extreme viewpoints? Is it biased?
    • Does it contain emotive or derogatory language?
  • Is there disclosure of author affiliations, or funding for the research or study?
  • Is there advertising alongside the information?
