Psychometrics: The Science of Assessment
Psychometrics: studying how we can improve assessment, so that the millions of decisions made every day from test scores can be fairer and stronger.
Analytics
Psychometricians love data. We were doing “data science” long before the term was cool. So, what kind of analysis do we do? Evaluate the performance of items and tests by looking at key statistics as well as fitting complex models like item response theory. This helps you improve your content, as well as serving as validity documentation. This, in turn, makes your assessment stronger, more accurate, more effective, and more defensible.
