What Is a CRAAP Test? Guide to Evaluating Source Credibility
Between the endless Instagram reels and viral TikToks claiming miracle cures, it's getting harder to figure out what's real anymore. Most people scroll past dozens of "groundbreaking studies" and "exclusive reports" before breakfast, and honestly, a lot of it's just made-up junk from someone's basement.
Back in 2004, some librarians at Cal State Chico got fed up with students citing sketchy websites and decided to do something about it. They came up with CRAAP - not the prettiest name, but it stuck. And yeah, it's basically just a way to check if what you're reading is legit or if someone's trying to sell you snake oil. Want to know more? Keep reading.

What Is the CRAAP Test?
Anyone who's spent time doing research knows that flashy websites don't always mean solid content. The CRAAP Test cuts through the noise with five basic checks:
Currency
Relevance
Authority
Accuracy
Purpose
Sarah Blakeslee and her team at Meriam Library developed this method back in 2004. They weren't trying to revolutionize research - they just wanted to give people a clear way to spot garbage sources before wasting time on them. Since then, schools and libraries across the country have picked it up as their go-to method for teaching smart research habits.
Think of CRAAP like a pre-flight checklist. Before taking off with any source, you run through these questions:
When was this published?
Does it actually help my research?
Who wrote it and what are their credentials?
Can these facts be verified?
What's the real agenda here?
Put them all together and you've got a pretty good sense of whether to trust a source or move on. No fancy algorithms needed - just common sense questions that separate the useful stuff from the junk.
The Five Components of the CRAAP Test
1. Currency: Is the Information Still Valid?
Some information goes stale faster than bread left on the counter. While certain sources hold up for decades, others become useless within months. Currency isn't just about dates - it's about whether the information still matters.
Key questions:
What's the publication or update date?
Do the links still work?
Has newer research changed what we know?
Does this still make sense today?
Think about cybersecurity - a 2016 guide to protecting your computer might as well be from 1916. The threats change weekly, and yesterday's solutions don't cut it anymore. You'd want something from 2023, preferably from someone who actually works in the field.
But here's the flip side: if you're studying Plato's Republic, an old translation might work fine. The ancient Greek hasn't changed since 380 BC. Though sure, a modern translation might be easier to understand.
<ProTip title="💡 Pro Tip:" description="For medical stuff, tech, or anything that changes fast, do not use anything older than 3-5 years unless you absolutely have to." />
2. Relevance: Does the Source Match Your Needs?
Just because something's good doesn't mean it's useful. A source needs to actually help answer your research question, or it's just taking up space.
Key questions:
Will this help prove my point?
Does it match my audience's knowledge level?
Who was this written for?
Have I looked at enough different viewpoints?
Let's say you're writing about climate policy. A National Geographic article might give you the basics, but for a college paper, you'll need meatier stuff - maybe reports from the U.S. Environmental Protection Agency (EPA) or analysis from environmental policy institutes.
<ProTip title="✅ Reminder:" description="Do not waste time reading the whole thing first - check the abstract or intro to see if it is worth your time." />
Nobody wants to be that student who cites a home gardening blog in their economics thesis. Sure, growing tomatoes and agricultural markets both involve farming, but one of these things is not like the other. Your sources need to actually support your argument, not just relate to it vaguely.
3. Authority: Who Created the Content?
These days, anyone with a phone can blast their thoughts to the world. That's why checking who's behind the information matters more than ever.
Check these basics:
The author's name and background
Where it got published
Any connection to legitimate institutions
Ways to contact the author
Whether experts reviewed it
What good authority looks like:
Studies from the World Health Organization (WHO)
Papers in scientific journals that other experts have checked
Books published by actual universities
What weak authority looks like:
Random posts with no author name
Articles that don't back up their claims
Websites plastered with ads and clickbait
Here's the thing: that fitness influencer might have 2 million followers and great abs, but when it comes to health advice, they don't stack up against the CDC or FDA. Numbers of likes don't equal expertise - credentials and real research do.
4. Accuracy: Can the Claims Be Verified?
Accuracy is about whether the source is factually correct, consistent, and unbiased. Many unreliable sources look polished but crumble when you fact-check them.
Questions to verify accuracy:
Does the author provide evidence and references?
Can the claims be cross-checked with other reliable sources?
Are there obvious grammar mistakes, typos, or sloppy errors?
Does the tone feel objective, or does it push an agenda?
<ProTip title="🔍 Pro Tip:" description="If a claim sounds too extreme or one-sided, look for at least two additional sources that confirm it." />
Example of accuracy in action:
A reputable medical article cites multiple studies and lists its references clearly.
A questionable blog says, “Doctors don’t want you to know this cure!” but provides no citations.
Why accuracy matters: In academic writing, citing inaccurate sources can undermine your entire argument. In everyday life, it can lead to poor decisions, such as following dangerous health advice.
5. Purpose: Why Does This Information Exist?
Purpose examines the motivation behind the content. Every piece of information has a goal, whether it’s to inform, sell, persuade, or entertain.
Ask yourself:
Is this content designed to educate or to push a product?
Does it use sensational or clickbait headlines?
Is it objective, or does it reflect bias?
Who is the target audience?
Example:
An educational website from the University of Illinois Math Learning Lab is created to inform students.
A health blog covered with affiliate links to supplements has a commercial purpose, it may mix facts with marketing.
Quick test: Check the About page, footer area, or author affiliations. These often reveal whether the content is nonprofit, academic, or commercial.
<ProTip title="🎯 Note:" description="Watch for subtle bias. Even reputable sites may have political or financial leanings." />
Why the CRAAP Test Matters in the Digital Age
The CRAAP Test isn’t just an academic exercise, it’s to help you stave off hoaxes.
The Problem of Misinformation
A Research study found that over 90% of U.S. adults say they encounter misinformation online. From health hoaxes to political propaganda, unreliable sources spread quickly. Without a filter like CRAAP, it’s easy to fall for bad information.
Benefits of Using CRAAP
Builds digital literacy
Strengthens academic research by ensuring reliable citations
Protects against confirmation bias by encouraging objectivity
Helps identify hidden agendas in commercial or political content
Think of CRAAP as your information radar system. It won’t block every bad source, but it will alert you when something looks suspicious.
Applying the CRAAP Test in Different Contexts
1. Academic Research
Nobody really talks about it much, but William Paterson University started something pretty smart with their CRAAP worksheets.
Students sit through these library sessions, but they actually end up learning how to spot sketchy online sources before they mess up their papers.
2. Professional Work
You'd be surprised how many pros lean on CRAAP without even knowing it. News reporters are obsessed with getting their facts straight (well, most of them anyway), and teachers spend hours picking through textbooks.
Some business folks learned this the hard way - trusting random market reports can cost them big time.
3. Everyday Decisions
Let's be real, this stuff comes in handy outside school too:
That weird Facebook post about microwaving lemons to cure everything? Yeah, check that
Someone's cousin posting get-rich-quick schemes on Instagram
Those super dramatic election headlines that don't quite add up
<ProTip title="🛠️ Pro Tip:" description="Practice CRAAP daily, even on social media. The more you use it, the faster it becomes second nature." />
Limitations and Critiques of the CRAAP Test
Here's the thing about CRAAP - it's good, but it's not perfect. Even professors who swear by it know it's got some weak spots.
Too much like a shopping list: Students just check boxes without really thinking. Been there, done that.
Who's really an expert anyway? Sometimes the best info comes from people who don't have fancy titles or degrees.
Hidden agendas are tricky: Big organizations with slick websites can hide their bias pretty well
Complementary Approaches
Lateral reading: Don't just stick to one page - open those tabs and see what the rest of the internet thinks.
SIFT method: This guy Mike Caulfield came up with it. Basically, stop and think before you share stuff, check who wrote it, find better sources if you need to.
Peer review stuff: For serious academic work, make sure actual experts looked it over first.
Mix these all together and you're way less likely to fall for fake news.
Practical Tips for Using CRAAP
Print a CRAAP Worksheet: CSU Chico's Meriam Library's got some pretty good ones. Just Google it.
Score your sources: Some teachers say to rate each part from 1-10. Add 'em up if you're into that kind of thing.
Mix it up: Try checking different kinds of stuff - maybe compare a science journal to some random blog post. You'll see the difference real quick.
CRAAP Test: Your Filter for Reliable Information
The CRAAP Test may sound like a joke, but its impact is no laughing matter. In an era where misinformation spreads quickly, having a structured way to evaluate sources is essential. By checking Currency, Relevance, Authority, Accuracy, and Purpose, you can separate strong, trustworthy sources from weak or misleading ones.
