It’s easy to say that the RIT scale is an equal-interval scale, but not as easy to back it up. This session will provide a conceptual review of the RIT scale and its characteristics and help to answer these questions: What is a RIT? What is a Rasch model? Why isn’t the number of correct answers used as the score? How are scores compared if students take different test items? Does a 200 RIT score from a third-grader mean the same thing as a 200 from an eighth grader?
- Gain a deeper understanding of the Rasch model.
