NUTR 6200: Research in Clinical Nutrition: Evaluate Webpages

Put the information to the CRAAP Test!

Information about almost any subject is easy to find; however, not all information is good information. An essential part of academic research and writing is learning how to critically analyze and evaluate your sources to eliminate old, incorrect, or irrelevant information. The CRAAP Test provides a good guide for analyzing your research sources.

Take the CRAAP test: Currency, Relevancy, Accuracy, Authority, Purpose.

By scoring each category on a scale from 1 to 10 (1=worst, 10=best possible), you can give each site a grade on a 50 point scale.

        45-50 Excellent | 40-44 Good | 35-39 Average | 30-34 Borderline | Below 30-Unacceptable
