How do I evaluate my sources?

Sometimes, you will need to use sources that are not academic. It is important to understand how to evaluate these sources, particularly if they are from the internet. The short video below explains the importance of evaluating your information. Another way to evaluate your sources is to use the CRAAP test. CRAAP stands for Currency, Relevance, Authority, Accuracy and Purpose. Below, you will see a number of questions related to each of this criteria. It's a good idea to ask yourself these questions when you're deciding whether you should use a particular source in your assignment.
