Khan Academy: Evaluating a Source's Reasoning and Evidence

Learn how to critically evaluate various types of sources in research with our step-by-step guide, covering everything from primary and secondary sources to web-based and print formats.

CRAAP Test

The CRAAP Test helps you evaluate sources across five key areas: Currency, Relevance, Authority, Accuracy, and Purpose. These elements help you determine whether a source is reliable enough for your research. Below, you'll find a quick snapshot of each area, with more detailed tips available by clicking the tabs.

CRAAP Test Elements
  • Currency: Is the information up-to-date?
  • Relevance: Does it directly relate to your topic?
  • Authority: Who is the author, and is the author credible?
  • Accuracy: Is the information correct and supported by evidence?
  • Purpose: Why was this information created, and is it biased?

Currency

Is the information up-to-date?

Currency refers to how recent the information is and whether its timeliness affects its accuracy or relevance. Depending on your topic, the importance of this element may vary. For instance, research in fields like technology, medicine, or current events requires the most up-to-date information, whereas historical or literary analysis may rely on older, foundational works. 

Things to Consider
  • Publication Date: Check when the source was published or last updated. 
  • Link Functionality (for web sources): In online sources, broken links or missing data could signal that the content is outdated or poorly maintained. 
  • Field of Study: Certain disciplines (like science or economics) evolve quickly, meaning older data might no longer be accurate or relevant.
Key Questions to Ask Yourself
  • When was the source published or last updated?
  • Does your research require current information, or is older data acceptable?
  • Have there been recent developments in the topic that would make this source less relevant?

Relevance

Does it directly relate to your topic?

Relevance helps you determine whether the source meets the needs of your research. A source might be accurate and current, but if it doesn't contribute meaningfully to your specific topic or research question, it might not be worth including. 

Things to Consider
  • Scope: Check if the source covers your topic in enough depth. Some sources might be too general, while others might be too specific or narrow to be useful.
  • Audience: Determine who the information was written for. Works can be geared toward experts, general readers, or students. Make sure the source matches the level of detail your project requires.
  • Connection to Your Research: Check if the source answers or supports your research question, or if it is only tangentially related.
Key Questions to Ask Yourself
  • Does this source help answer my research question or provide essential background information?
  • Is the level of detail appropriate for my project?
  • Is the source intended for the right audience—students, professionals, or general readers?

Authority

Who is the author, and is the author credible?

Authority focuses on the expertise and qualifications of the author or organization responsible for the source. The credibility of your source heavily depends on the trustworthiness of the creator and is especially important in academic and professional research.

Things to Consider
  • Author's Credentials: Look for the author's qualifications, such as their educational background, institutional affiliation, or professional experience. Are they recognized as an expert in the field?
  • Link Functionality (for web sources): Check if the source was published by a reputable journal, academic press, or well-known organization. Publishers and institutions with established reputations are more likely to ensure the information is reliable.
  • Field of Study: Check if the source cites other credible, authoritative sources. This often indicates a well-researched and credible work.
Key Questions to Ask Yourself
  • What are the author's credentials? Are they an expert in this field?
  • Is the source affiliated with a respected institution or publisher?
  • Does the source reference other credible and reliable works?

Accuracy

Is the information correct and supported by evidence?

Accuracy ensures that the information in your source is correct and reliable. A source might be current and relevant, but if it contains inaccuracies or is poorly researched, it can undermine your entire project.  

Things to Consider
  • Evidence and Support: Check if the source provides evidence for its claims, such as data, statistics, or citations. Well-supported information is typically more reliable.
  • Cross-Verification: Compare the information with other trusted sources. If multiple reputable sources agree, it's more likely to be accurate. 
  • Error Checking: Looking for spelling and grammatical errors, which can sometimes indicate a lack of attention to detail. Also, watch for inconsistencies in the data presented.
Key Questions to Ask Yourself
  • Does the source provide evidence to back up its claims? What kind of evidence is used? 
  • Can the information be verified by other reliable sources?
  • Are their noticeable errors or inconsistencies in the data or presentation?

Purpose

Why was this information created and is it biased?

Purpose examines why the information was created and whether it has any bias or agenda. Understanding the purpose behind the source helps you assess its objectivity and relevance to your research.

Things to Consider
  • Author's Intent: Determine if the source was created to inform, persuade, entertain, or sell something. Sources with commercial or persuasive intent may be biased.
  • Bias and Objectivity: Evaluate whether the information is presented fairly or if there is a noticeable bias. A balanced perspective is often more credible.  
  • Audience and Motivation: Consider who the intended audience is and how that might influence the content. A source could try to appeal to a specific group or promote a particular viewpoint.
Key Questions to Ask Yourself
  • What is the primary purpose of this source? To inform, persuade, or entertain?
  • Is there any evidence bias, or does the source strive for objectivity?
  • How does the intended audience affect the content and its reliability?

FAQs
