Psychometricians are scarce and expensive, come in a variety of flavors, and sometimes are hard to understand. Many of their analyses they perform can be run by anybody quantitatively-savvy, so when does their unique training and perspective really matter? What does the “art of psychometrics” add to what Data Science can provide?
We will talk about the role of psychometricians in:
Job analyses and content outline development
Scoring design, including weighting
Determining passing standards
Test performance monitoring
Item and test analyses
