CRAP Test for Website Evaluation

Jul 12, 2025

Overview

This lecture explains the CRAP Test, a method for evaluating the credibility and validity of website information using the criteria: Currency, Reliability, Authority, and Purpose.

The CRAP Test Overview

  • CRAP stands for Currency, Reliability, Authority, and Purpose.
  • This framework helps determine if a website’s information is credible and valid.

Currency

  • Check how recent the information is by finding a publication date on the article or URL.
  • Look for the last website update, usually found at the bottom of the page.
  • Test if links work; broken links may indicate outdated content.
  • Decide if the source’s currency matches your topic’s needs; fast-changing fields require very recent data.

Reliability

  • Examine the type of information: fact-based or opinion-based (watch for “I think” or “In my opinion”).
  • Check if the author provides data, charts, graphs, or quotations with references.
  • Reliable sites list sources or give links to data, images, or claims.
  • Without references, information accuracy cannot be confirmed.

Authority

  • Identify the website creator and check if the site title matches the URL.
  • Trusted sites often end with .gov (government) or .edu (education).
  • .com, .net, and .org can be purchased by anyone and require further checking.
  • Look for the author's name and credentials, typically near the article title or in a bio.

Purpose

  • Consider why the site exists (inform, sell, persuade, entertain).
  • Sites with excessive ads or short, click-driven content may prioritize profit over accuracy.
  • If the site encourages purchases, information could be biased.
