What is the CRAAP test?
The CRAAP test is a simplified framework used to evaluate the reliability and credibility of information sources. It is an acronym that stands for Currency, Relevance, Authority, Accuracy, and Purpose. Students use this checklist to determine if a source is high quality enough to be cited in an academic essay or research project.
The five pillars of the CRAAP test
To apply the CRAAP test, you must analyze a source based on these five specific criteria:
- Currency: The timeliness of the information. Check when the information was published, posted, or last updated.
- Relevance: The importance of the information for your specific needs. Determine if the source covers your topic in enough depth for your assignment.
- Authority: The source of the information. Identify the author, their credentials, their organizational affiliations, and their reputation.
- Accuracy: The reliability, truthfulness, and correctness of the content. Look for evidence, peer review, and citations that support the claims made.
- Purpose: The reason the information exists. Analyze whether the intent is to inform, teach, sell, entertain, or persuade.
CRAAP test evaluation criteria
| Dimension | Key Question | What to Look For |
|---|---|---|
| Currency | Is the info current? | Publication dates and functional links |
| Relevance | Does it fit my topic? | Level of detail and target audience |
| Authority | Who is the author? | Degrees, experience, and publisher reputation |
| Accuracy | Is it truthful? | Citations, lack of typos, and verifiable data |
| Purpose | Why was it written? | Objective tone vs. hidden agendas or ads |
| Scope | Is it comprehensive? | Coverage of the topic compared to other sources |
CRAAP test example: Academic vs. popular sources
Consider a research paper on climate change. Here is how you would apply the CRAAP test to two different types of sources: **Source A: A Peer-Reviewed Journal Article (2023)** * **Currency:** Published last year; highly current. * **Authority:** Written by PhD climatologists at a major university. * **Accuracy:** Includes 40+ citations and raw data tables. * **Verdict:** Strong source for academic writing. **Source B: A Personal Blog Post (2015)** * **Currency:** Nearly a decade old; likely outdated. * **Authority:** Written by a hobbyist with no formal scientific training. * **Accuracy:** No citations provided; relies on personal anecdotes. * **Verdict:** Weak source; do not use for academic research.
When to use the CRAAP test
Use the CRAAP test every time you find a source via a general search engine like Google. While library databases usually contain vetted materials, the open web requires rigorous screening. If a source fails even one letter of the CRAAP acronym, such as having a biased Purpose or an anonymous Authority, it is usually best to find a more reputable alternative.
