TRAAP is a simple acronym that can be used as a tool for evaluating information and determining if you're heading toward a research trap. Each letter in TRAAP represents a criteria by which to measure the reliability and appropriateness of sources.
Timeliness: The currency of the information
Relevance: The information meets your assignment needs
Authority: The source of the information
Accuracy: The reliability and correctness of the information
Purpose: The reason the information exists
A lot of your sources will come from online sources. In particular, think about authority when analyzing a website for credibility. Good sources come from those with authority on the topic. People who are considered qualified to speak on the topic because they have the credentials and experience behind them.
Good Sources
