Description¶

The CRAAP Test is a source-evaluation rubric developed by the Meriam Library at California State University, Chico (Blakeslee, 2004). Students score a website against five criteria — Currency, Relevance, Authority, Accuracy, and Purpose — using a worksheet that asks about surface features such as domain suffix, spelling and grammar, listed authors, and dates updated. The result is a numeric credibility score used to accept or reject a source.

Design Implications¶

The CRAAP Test gives learners a concrete, structured procedure for a judgment task that novices otherwise approach haphazardly, functioning as a Scaffolding device that externalizes evaluation criteria Provide Guidance. Structured evaluation instruction of this kind does improve students' source-evaluation outcomes compared with no instruction Civic online reasoning instruction improves evaluation [+S]. However, research on how professional fact-checkers evaluate sources shows that checklist approaches based on internal features of a page are markedly less effective than lateral reading — leaving the page to check claims against other sources Checklist evaluation is ineffective online [-M]. Designers should treat CRAAP as an entry point, not the end state of evaluation instruction.

Context¶

Requirements¶

• A printed or digital CRAAP worksheet with the five criteria and scoring items
• A set of authentic websites to evaluate, ideally including deliberately misleading ones (e.g., professional-looking hoax sites)
• Instructor modeling of how to apply each criterion (Think-Aloud) before independent practice (Practice)
• A concrete evaluation task with real sources to judge, not hypotheticals
• A decision point: learners must actually accept or reject a source, not merely fill in the checklist

Constraints¶

• Checklist scoring rewards polished design and penalizes informal style — professional misinformation passes while legitimate amateur sources fail Checklist evaluation is ineffective online [-M]
• All criteria are vertical (on-page) checks; none require verifying claims against the wider web, which is what expert fact-checkers actually do Checklist evaluation is ineffective online [-M]
• Scoring can become a mechanical box-ticking exercise divorced from actual judgment of the source's claims
• Currency and domain heuristics (e.g., ".org means trustworthy") are unreliable signals that students often overgeneralize
• Checklist evaluation is vertical — it examines the source itself — and this is precisely where it fails: professional fact-checkers leave the page and read laterally, and students taught only checklists are far more likely to be deceived by biased or fake sites than students taught lateral reading [-S]
• Surface features can satisfy criteria while the source remains unreliable: a current, well-designed, professionally branded site can still be misinformation; students often treat "looks professional" as evidence of authority [-M]
• The Accuracy criterion is largely unanswerable by novices, who lack the domain knowledge to verify claims independently — the checklist asks them to do something they cannot do [~M]
• As a fixed rubric it can become a box-ticking ritual; learners complete it without changing their judgments about the source [-W]
• Less useful for evaluating sources where authority is distributed or contested (social media posts, datasets, preprints) [~W]

Implementation Variability¶

• Use as a discussion frame rather than a scored worksheet — criteria become prompts for reasoning, not points
• Pair with lateral-reading tasks: after CRAAP scoring, students must search for what other sites say about the source
• Adapt criteria to specific disciplines (e.g., primary vs. secondary sources in history)
• Use with Comparing Cases: evaluate a credible and a hoax source side by side to sharpen discrimination
• Lateral-reading hybrid: teach CRAAP as a starting frame, then immediately pivot to opening new tabs to check the organization, author, and claims against independent sources — the approach validated in the Stanford History Education Group studies
• SIFT adaptation: Caulfield's SIFT (Stop, Investigate the source, Find better coverage, Trace claims to the original) replaces the checklist with four fast moves aligned to expert practice
• Discipline-specific variants: rubrics adapted for evaluating empirical research (e.g., CASP appraisal checklists) where accuracy criteria are answerable via methodological quality rather than domain knowledge
• Comparative evaluation: asking learners to rank several sources on the same topic forces discrimination rather than absolute judgment

Target Learners¶

• Middle and secondary students encountering web-source evaluation for the first time
• Undergraduates in introductory research or information-literacy instruction
• Less effective alone for advanced students, who need strategies matching expert practice (lateral reading, claim verification) Checklist evaluation is ineffective online [~M]
• Novices — secondary and early undergraduate students — encountering source evaluation for the first time, for whom the checklist provides an entry-level schema
• Students in first-year composition or information-literacy instruction sessions
• Less beneficial for advanced students, who need domain-based appraisal skills (methodological critique) rather than generic criteria [~M]
• Weaker as a standalone intervention for K–12 students: large-scale assessments show most students struggle to evaluate online sources even after checklist-style instruction, while explicit lateral-reading lessons produce measurable gains [-M]

Target Learning Goals¶

• Information literacy: judging source credibility
• Critical evaluation: distinguishing evidence quality from presentation quality
• Civic online reasoning: evaluating information encountered in everyday media Civic online reasoning instruction improves evaluation [+S]
• Information literacy: judging the credibility of sources before use
• Metacognitive habits: pausing before accepting or sharing information

Instructions¶

1. Introduce the five criteria and model applying them to one website, verbalizing each judgment (Think-Aloud).
2. Have students independently score 2–3 websites with the worksheet (Practice), including at least one deceptive source.
3. Debrief scores as a class, surfacing disagreements — where students scored the same site differently is where reasoning becomes visible.
4. Extend beyond the checklist: ask students to verify one factual claim from each site by searching what independent sources say (lateral reading), and compare what this reveals that the checklist missed.
5. Fade the worksheet over successive tasks so students internalize evaluation as habitual questioning rather than form-filling (Fading).

Related Strategies¶

• Lateral Reading — the expert strategy research recommends supplementing or replacing checklist evaluation; leave the page to check the source
• Civic Online Reasoning Curriculum — Stanford's published curriculum teaching evaluation through lateral reading and claim verification (Stanford History Education Group)
• Fact-Checking Tasks — applying evaluation criteria to specific claims rather than whole pages
• Lateral reading — the expert strategy that research shows outperforms checklist evaluation; best taught alongside or instead of CRAAP
• SIFT method — a streamlined successor built on fact-checker practice
• Comparing cases — evaluating multiple sources side by side builds the discrimination a single-source checklist cannot
• Parents and educators should search multiple sources — app stores, expert review sites, and producers' websites — when selecting literacy apps
• Extend multiple-text strategy assessment with sourcing and contextualization items and validate against online traces
