The CRAAP test is a five-point checklist for evaluating whether a source is trustworthy enough to cite, scoring it on Currency, Relevance, Authority, Accuracy and Purpose. Developed by librarians at California State University, Chico, it gives students a quick, repeatable way to separate credible evidence from outdated, biased or unreliable material before it ever reaches a reference list. This guide explains what the CRAAP test stands for, how to apply each of the five criteria with the right questions, a scoring system, a worked example, a printable checklist and a table comparing how the test behaves across books, journal articles, news and websites.
What is the CRAAP test?
The CRAAP test is a straightforward checklist used to evaluate a source’s credibility and relevance before you rely on it in academic work. It was developed by the Meriam Library at California State University, Chico, as a teaching tool, and its usefulness spread so quickly that universities and libraries worldwide now adopt and adapt it. CRAAP stands for Currency, Relevance, Authority, Accuracy and Purpose — five lenses that, taken together, tell you whether a source is fit to be cited.
In a digital age rife with information, distinguishing genuine, useful sources from those that are inaccurate or even deliberately deceptive has become an indispensable academic skill. Whether you are a first-year undergraduate, a master’s student or a doctoral researcher, you need a reliable way to discern the quality of what you read. The CRAAP test gives you that — a quick mental routine you can run on any webpage, book or article in under five minutes. It sits at the heart of good practice when working with a source of any kind, and it complements the broader skill of learning how to evaluate sources across an entire literature search.
Crucially, the CRAAP test is not a pass-or-fail gate. A source can score poorly on one criterion and still earn its place: a 1995 government report might fail Currency but be the authoritative primary source on a policy of that era. The test prompts you to ask the right questions; your judgement, in the context of your research topic, supplies the answers.
What does CRAAP stand for?
CRAAP is an acronym for the five criteria you weigh up when judging a source. The structured approach below turns each letter into a small set of questions, so evaluation becomes a habit rather than a guess.
| Letter | Criterion | Core question |
|---|---|---|
| C | Currency | When was it published or last updated, and is that recent enough for my topic? |
| R | Relevance | Does it directly address my research question, at the right level? |
| A | Authority | Who wrote it, and what makes them qualified to? |
| A | Accuracy | Is the information evidence-based, verifiable and error-free? |
| P | Purpose | Why was it created — to inform, persuade, entertain or sell? |
How to apply the CRAAP test: the five criteria
Work through the criteria in order. For each, ask the listed questions and form a quick verdict. Below, every criterion explains what it covers, the questions to ask and why it matters for your work.
1. Currency: the timeliness of the information
Currency refers to how recent the information is. In fast-moving fields such as technology, medicine or law, material that is only a few years old can already be obsolete; in history or literary theory, an older source may remain authoritative. The point is not “newer is always better” but “appropriately current for this topic”.
Questions to ask:
- When was the information published or last updated?
- Have newer sources or findings since revised this picture?
- Does your topic demand the very latest data, or are older sources suitable?
- If it is a webpage, are the links still live and the references still maintained?
Why it matters: the pace at which new information is produced is staggering. Some topics, such as historical analyses, are served well by older sources; others, especially in the sciences, require the most up-to-date data. Ensuring your sources are current minimises the risk of relaying outdated or superseded findings in your own work.
2. Relevance: the importance of the information for your needs
Relevance considers whether the information actually meets your research needs. A source can be impeccably credible and bang up to date yet still be the wrong source for you — pitched at the wrong audience, or tangential to your argument.
Questions to ask:
- Does the information relate directly to your topic or research question?
- Who is the intended audience — is it too basic, or too specialised, for your needs?
- Would another source offer a more applicable or better-evidenced perspective?
- Does it add something your existing sources do not already cover?
Why it matters: if a source does not address your question, it dilutes your literature review and pads your reference list without strengthening your argument. Always check that the information you include is directly relevant to the case you are building.
3. Authority: the source of the information
Authority concerns the credentials of the author, publisher or organisation behind the information. The credibility of any claim is tied to the qualifications and reputation of whoever is making it. This criterion is closely linked to the wider question of what are credible sources in the first place.
Questions to ask:
- Who is the author, publisher or sponsoring body, and what are their credentials?
- Is the source backed by a reputable institution, university or professional organisation?
- Is the author affiliated with a recognised body, and is contact information provided for verification?
- Does the domain offer a clue — .ac.uk, .edu and .gov sites carry institutional accountability that .com sites may not?
Why it matters: academic articles undergo rigorous peer review, ensuring experts in the field have vetted the work before publication. Recognising and relying on authoritative sources bolsters the reliability of your own analysis and your conclusions. If you are unsure how to confirm a journal’s standing, our guide to finding peer-reviewed sources walks you through the checks.
4. Accuracy: the reliability and truthfulness of the content
Accuracy ensures the information presented is reliable, truthful and free from errors. Even an authoritative author can publish a flawed piece, so you verify the content itself, not just the byline.
Questions to ask:
- Where does the information come from — are there references or citations you can trace?
- Has the work been peer-reviewed, edited or fact-checked?
- Can the key claims be corroborated by an independent source?
- Are there glaring errors, typos or internal inconsistencies that undermine confidence?
Why it matters: information riddled with errors — factual, statistical or grammatical — loses credibility, and any work that cites it inherits that weakness. Verifying accuracy keeps your own research to a standard of reliability and truthfulness that examiners expect.
5. Purpose: the reason the information exists
Purpose deals with the motivations behind the information. It asks whether the content was created to inform, persuade, entertain or sell — and who stands to benefit from your believing it.
Questions to ask:
- Why was this information produced, and for whom?
- Is there an apparent bias or slant — is the author trying to sell something or advocate a position?
- Who funded the study or publication, and might they have a stake in its findings?
- Does the language stay objective, or does it lean on emotive, promotional or one-sided framing?
Why it matters: even accurate, timely information can be skewed by commercial or ideological motives. Understanding the purpose behind a source helps you judge its objectivity and decide how much weight it deserves in a balanced argument.
“The CRAAP Test gives students a memorable, repeatable framework for asking the right questions of any information source — the goal is not a perfect score but informed, deliberate judgement.” — Meriam Library, California State University, Chico (originators of the test)
Scoring the CRAAP test
Many universities turn the five criteria into a simple scoring sheet so evaluation feels less subjective. A common approach is to rate each criterion from 1 (poor) to 10 (excellent), giving a maximum of 50. The score is a guide, not a verdict — use it to compare candidate sources and to flag weaknesses, then apply judgement.
| Total score (out of 50) | Interpretation | What to do |
|---|---|---|
| 45–50 | Excellent — strong on every criterion | Cite with confidence |
| 40–44 | Good — minor weaknesses | Use, noting any caveat |
| 35–39 | Acceptable — some concerns | Use cautiously; corroborate claims |
| Below 35 | Weak — significant gaps | Look for a stronger alternative |
Treat a low score on a single criterion as a prompt to investigate, not an automatic rejection. A primary source — an original speech, dataset or historical document — may legitimately score low on Currency yet be exactly what your argument needs.
Worked example: applying the CRAAP test
Imagine you are writing a dissertation on the mental-health effects of remote working and you find an article online. Here is how a full CRAAP evaluation might run.
Currency (9/10): Published in 2024 — ideal for a topic where workplace norms have shifted rapidly since 2020.
Relevance (8/10): Directly addresses wellbeing and remote work; the sample is office workers, which fits the research question, though it is US-based rather than UK.
Authority (10/10): Written by three academics at named universities and published in a peer-reviewed journal indexed in major databases.
Accuracy (9/10): Methods are clearly described, the dataset is shared, and the conclusions are supported by the statistics presented; references are traceable.
Purpose (9/10): Created to report empirical findings, not to sell a product; funding is disclosed and shows no obvious conflict of interest.
Total: 45/50 — Excellent. Cite with confidence, simply noting the US sample when generalising to a UK context.
Now contrast that with a source that scores poorly: a 2011 blog post on a supplement-retailer’s website claiming “remote workers need our wellbeing capsules”. It fails Currency (dated), Authority (anonymous, commercial), Accuracy (no citations) and Purpose (selling a product). Its only redeeming feature is loose Relevance — and that is not enough to earn a citation.
Applying the CRAAP test to different source types
The five criteria stay the same, but the warning signs differ by format. The table below shows what to focus on for each common source type you will meet when writing a research paper or dissertation.
| Source type | Watch Currency for… | Watch Authority for… | Watch Purpose for… |
|---|---|---|---|
| Books | Whether a newer edition exists | Author’s standing; reputable publisher | Inform vs. persuade vs. textbook |
| Journal articles | Whether later studies supersede it | Peer review; author affiliations | Research vs. advocacy; funding |
| News articles | How recent; is the story still live | Publication’s reputation; named reporter | Reporting vs. opinion vs. advertorial |
| Websites | Last-updated date; dead links | Domain (.ac.uk/.gov) and named owner | Inform vs. sell vs. lobby |
Books
Check whether the publication date is recent enough for your topic and whether a newer edition has appeared. A 1998 cellular-biology textbook may be outdated for current research even if the author is respected, whereas a classic theoretical text can remain authoritative for decades. Confirm the publisher is reputable and the content cited and referenced.
Journal articles
Ask when the article was published and whether later research has revised its findings, who the authors are and what their affiliations indicate, and whether the journal is genuinely peer-reviewed. A 2023 article from a reputable, indexed journal on climate change is likely to be both current and authoritative; a paper in a pay-to-publish “predatory” journal is not, regardless of its claims.
News articles
Judge how recent the report is and whether the issue still matters, which publication produced it and whether the journalist has subject expertise, whether multiple sources are used, and whether the piece is news, opinion or an advertorial. A single 2019 tabloid story with no named sources scores far lower than a 2024 investigation in an established broadsheet that quotes documents and experts.
Websites
Websites are the most variable source type and where the CRAAP test earns its keep. Look for a last-updated date, a named author or organisation, an “About” page, working references and a domain that signals accountability. A government statistics portal and an anonymous content farm can sit side by side in your search results; CRAAP is how you tell them apart.
Printable CRAAP test checklist
Run any source through this quick checklist. If you find yourself answering “no” or “unclear” repeatedly, treat that as a red flag and look for something stronger.
- Currency: The publication or last-updated date is appropriate for my topic.
- Relevance: The content directly addresses my research question at the right level.
- Authority: The author or organisation is named, qualified and reputable.
- Accuracy: Claims are evidence-based, cited and verifiable elsewhere.
- Purpose: The aim is to inform, and any bias or commercial interest is transparent.
Limitations of the CRAAP test (and what to add)
The CRAAP test is an excellent starting point, but it has known limitations. Because it asks you to inspect a source in isolation, a polished, professional-looking site can score well on surface criteria while still being misleading. Many information-literacy specialists now pair CRAAP with lateral reading — leaving the page to check what other independent sources say about the author or organisation — and with the SIFT method (Stop, Investigate the source, Find better coverage, Trace claims to their origin). Use CRAAP to structure your first pass, then read laterally to confirm authority and purpose. Together, these habits make your evaluation far harder to fool, and they keep your reference list robust enough to withstand examiner scrutiny.
