The CRAAP Test: Evaluating Your Ingredients
Not all sources are created equal. Here’s how to tell the good from the bad.
In our Research Recipes notes, we compared finding sources to shopping for ingredients. We talked about avoiding “processed” ingredients, checking expiration dates, and taste testing before you commit. But how do you actually evaluate a source once you’ve found it? How do you know whether it belongs in your paper or back on the shelf?
That’s where the CRAAP Test comes in. CRAAP is an acronym that gives you five criteria for evaluating any source: Currency, Relevance, Authority, Accuracy, and Purpose. Before you use a source in your research, ask yourself: Is my resource CRAAP?
Think of it this way: when you’re shopping for ingredients, you don’t just grab the first thing you see. You check the label, look at the expiration date, and consider whether it’s actually what your recipe calls for. The CRAAP Test is your label-reading process for research sources.
C — Currency: Is It Fresh?
Currency refers to the timeliness of the information. Just as you wouldn’t want to cook with expired ingredients, you generally don’t want to build your research on outdated information.
- When was the information published or last updated? If your source is a website, check for a publication or revision date. If it has several broken links, that’s a sign no one is maintaining the page.
- Does timeliness matter for your topic? It depends on the subject. For fields that are always changing—science, technology, medicine—you’ll want the most current sources available. If you’re writing about cancer treatment, for example, a book from the 1950s won’t reflect modern medical practices. On the other hand, a firsthand account of a historical event (a primary source) can be valuable precisely because it was written at the time, even if that was centuries ago.
- The bottom line: Consider what “current” means for your specific topic, and make sure your sources reflect the most appropriate timeframe.
R — Relevance: Does It Fit Your Recipe?
Relevance is about whether the information actually serves your needs. In cooking terms, it doesn’t matter how fresh an ingredient is if it doesn’t belong in the dish you’re making.
- Does the source relate to your topic or answer your research question? If you created a keyword list from your research outline (your “recipe”), check whether the source actually speaks to those specific points.
- Who is the intended audience? A source written for children may be too basic, while a highly technical journal article may be more advanced than you need. Look for sources at an appropriate level for your assignment.
- Is this the best source available? Have you looked at a variety of options before settling on this one? Your goal is to be able to say, “I know what I’m talking about because I’ve used the best resources available.” A clip from Sesame Street might be a fun way to introduce a topic in a presentation, but it shouldn’t be your main source of information for an academic paper.
A — Authority: Who’s in the Kitchen?
Authority asks you to consider who created the information and whether they’re qualified to speak on the subject. A great restaurant has trained chefs; your research should draw on credible experts.
- Who is the author? Are their credentials or organizational affiliations listed? What qualifications do they have? Are they recognized as an expert in this subject area?
- Who published or sponsored the source? A peer-reviewed journal, a university press, or a reputable news organization carries more weight than an anonymous blog post.
- Consider the source carefully. To borrow an example from the video: if you’re writing a biology paper about butterflies, your Grandma Betty might have a lovely butterfly blog—but unless she has scientific credentials, she shouldn’t be your main source. Instead, look for authors with relevant degrees, professional experience, or institutional backing in the appropriate field.
A — Accuracy: Can You Trust What’s Inside?
Accuracy concerns the reliability, truthfulness, and correctness of the content. Even a source from a credible author can contain errors, so it’s worth looking more closely.
- Is the information supported by evidence? Does the author cite their own sources? Can you verify the claims in another source?
- Has the source been reviewed by editors or other experts? In college, professors often require peer-reviewed sources. Peer review is the process by which an author’s professional peers evaluate a paper before publication and recommend whether it should be published, revised, or rejected. Peer-reviewed sources go through a strict review process and are only published when they meet specific standards—which means you can trust that experts have verified the information.
- Why does peer review matter? Think of it as a quality inspection. Just as a restaurant health inspection gives you confidence that the kitchen meets safety standards, peer review gives you confidence that a source meets scholarly standards.
P — Purpose: Why Does This Source Exist?
Purpose asks you to consider why the information was created in the first place. Not every source exists to inform—some are designed to persuade, sell, or entertain, and that affects how much you should rely on them.
- What is the purpose of the information? Is it meant to inform, persuade, entertain, or sell something? Do the authors or sponsors make their intentions clear?
- Is the information objective and unbiased? Is it based on fact, or does it lean on opinion or propaganda? If someone is trying to sell you something, they may not be giving you the full picture.
- Entertainment is not the same as information. You could quote the musical Hamilton in a paper about the American Revolution, but you wouldn’t want it to be your main source. A show like Hamilton may include historical details, but its purpose is to entertain—facts may be altered to put on a better performance. Make sure your sources come from places whose primary purpose is to provide factual, reliable information.
Putting It All Together
The CRAAP Test gives you a reliable, repeatable way to evaluate any source you encounter during your research. Before you add a source to your paper, run through the checklist:
- Currency — Is the information current enough for my topic?
- Relevance — Does this source actually address my research question?
- Authority — Is the author qualified and the publisher reputable?
- Accuracy — Is the information supported by evidence and verified by experts?
- Purpose — Was this source created to inform, or does it have another agenda?
Remember, in our Research Recipes framework, sources are your ingredients. The CRAAP Test is how you inspect those ingredients before they go into your meal. A paper built on well-evaluated, high-quality sources is like a dish made with the freshest, best ingredients—the quality shows in the final product.
Happy researching!
