CARS Checklist for Evaluating Websites

CARS is an acronym for Credibility, Accuracy, Reasonableness, and Support.

CARS in a Nutshell

  • Credibility - trustworthy source, author’s credentials, evidence of quality control, known or respected authority, organizational support. Goal: an authoritative source, a source that supplies some good evidence that allows you to trust it.
  • Accuracy - up to date, factual, detailed, exact, comprehensive, audience and purpose reflect intentions of completeness and accuracy. Goal: a source that is correct today (not yesterday), a source that gives the whole truth.
  • Reasonableness - fair, balanced, objective, reasoned, no conflict of interest, absence of fallacies or slanted tone. Goal: a source that engages the subject thoughtfully and reasonably, concerned with the truth.
  • Support - listed sources, contact information, available corroboration, claims supported, documentation supplied. Goal: a source that provides convincing evidence for the claims made, a source you can triangulate (find at least two other sources that support it).
C is for Credibility

Can you trust this site?

Who wrote it? Is that person or organization reputable? An Authority? What is his/her background or credentials?

What organization sponsored the site? Look at the domain names. Is it .org, .edu, .gov, .com? Domains can be an indication of authority.

If you can't find who wrote it, don't trust it.

R is for Reasonableness

What is the purpose of the site? Mission of the organization?

Is the Information fair, balanced, objective, and correct?

Is the information one-sided or slanted?
