Item Response Theory

  • jMetrik: Free and open source software for running psychometric analysis (item response theory). There is a version for both Mac and PC.
  • IRT Pro: An IRT software just for PC. I’ve used it and really like it. There is a free version that limits the number of cases (up to 1,000) and items that you can have.
  • The Basics of Item Response Theory, by Frank Baker: From what I gather it is one of the key resources on the web for learning IRT.
  • A visual guide to item response theory: As I am working to learn IRT this is another resource that is cited over and over.
