The CRAAP Test: Five Questions That Expose Bad Sources

In 2019, a study by the Stanford History Education Group found that 96 percent of high school students couldn't reliably identify whether a photograph used by an advocacy group came from a credible source. A separate study found that professional fact-checkers evaluate websites very differently from students: fact-checkers immediately open new tabs to see what others say about the source, while students tended to trust professional-looking design. Information literacy is not about being skeptical of everything. It's about having a fast, reliable method for sorting good sources from bad ones. The CRAAP Test — developed by librarians at California State University, Chico — gives you exactly that: five questions you can apply to any source in under five minutes.

By the end of this lesson, you will be able to: • Define and apply each of the five CRAAP criteria to any source. • Score a source using the CRAAP framework and make a reliability judgment. • Explain why visually polished sources can still fail the CRAAP test. • Identify at least two real limitations of the CRAAP test itself.

CRAAP stands for Currency, Relevance, Authority, Accuracy, and Purpose. C — Currency: How recent is the information? A 2003 article on COVID-19 treatments is useless. A 2003 article on the causes of World War I may be perfectly valid. The right question is: does the age of this source matter for my topic? R — Relevance: Does the source actually address my research question? A peer-reviewed study on caffeine and sleep in adults is not relevant if you're researching caffeine in children. Relevance also includes audience: is this source written for experts, students, or the general public? A — Authority: Who wrote or published this? What are their credentials for making claims on this specific topic? A cardiologist writing about heart disease is authoritative; a cardiologist writing about vaccine immunology is not necessarily an expert on that topic. A — Accuracy: Is the information correct and verifiable? Does the source cite evidence? Can you find the same claim confirmed by independent credible sources? P — Purpose: Why does this source exist — to inform, persuade, entertain, or sell? A pharmaceutical company's website discussing its own drug's side effects has a built-in conflict of interest. That doesn't make it useless, but it changes how you read it.

Source: An article titled 'Vaccines Cause Autism: The Evidence' on 'HealthTruthNow.net'. No author is listed. The site has a PayPal donate button. The article's one cited study links to a page that no longer exists. Currency: No publication date visible. Unknown — fails. Relevance: Could be relevant if researching vaccine misinformation — but not for researching vaccine safety. Authority: No author listed, no institutional affiliation. Appears to be run by a private individual. Fails. Accuracy: The sole citation is a dead link. The central claim has been thoroughly debunked. The original 1998 Wakefield study was retracted by The Lancet and Wakefield lost his medical license for fraud. Fails badly. Purpose: The donation button suggests financial motivation. The framing implies advocacy, not neutral reporting. Fails. Verdict: FAIL on Authority, Accuracy, and Purpose. This source should not be used for any purpose except studying how misinformation is packaged.

The CRAAP test is a useful starting framework, but it has real limitations: 1. It can overvalue credentialed sources. Peer-reviewed journals have published fraudulent studies — the Wakefield vaccine paper was in The Lancet. Authority does not guarantee accuracy. 2. It underweights lateral reading. Stanford researchers found the most effective strategy is to immediately open new tabs to see what independent sources say about a source, rather than spending more time on the source itself. 3. Purpose is hard to assess quickly. Many sites hide their funding sources, making conflict of interest difficult to spot. 4. Currency standards vary wildly by field. A 2001 physics paper might be cutting-edge; a 2001 medical treatment guideline is almost certainly outdated. Use CRAAP as a starting point, not an ending point. It's most powerful when combined with lateral reading and explicit source comparison.
