Mathematics: Evaluating Sources

Always evaluate your sources (online or in print) for CRAAP :

• Currency
  • When was the information published? Is it current? Up-to-date?
• Relevance
  • Does the information relate to your topic? Who is the intended audience?
• Authority
  • What are the author's credentials? Organizational affiliations? Is the author qualified to write on this topic? 
• Accuracy
  • Is the information supported by evidence? Can you verify it from another source? Are there typos, spelling, grammatical errors?
• Purpose
  • Is the information fact, opinion, propaganda? Does the author make his/her intentions/purpose clear?
