Abstract: This presentation won’t really teach you everything you ever wanted to know about psychometrics – that’s impossible. But it will cover five key questions that any analyst or test user should ask, gives some background on why they are so important, and offers some advice on how to go about answering them. These five questions are designed to address some of the most common issues analysts struggle with when conducting psychometric analyses. They will also assist test score users to help them to understand whether the technical documentation they have is adequate to for making sound decisions and defending them legally, if necessary. The presentation is oriented toward beginning to moderately experienced researchers and professionals who use psychometric information to make decisions.
