Item response theory

Date: Friday, October 14th

Facilitator: Carlos Fernando Collares, Maastricht University. Department of Educational Development and Research. Faculty of Health, Medicine and Life Sciences.

Workshop description

"Item response theory", also known as IRT, is a name that does not make justice to what it actually is: a psychometric paradigm comprised of a family of models which attempt to establish a mathematical function between the probability of success in test items and the proficiency of the test takers.

In this workshop, IRT and classical test theory will be compared in terms of advantages and disadvantages. The usefulness of IRT in medical education will be discussed. Participants are not expected to have previous experience on psychometrics or IRT.

All participants are invited to bring their own datasets so that they can perform their own analyses and interpret their results during the workshop.

Objectives of the session and the knowledge, attitudes and skills that participants should gain from it

By the end of the workshop, participants are expected to:

  • enlist the differences between classical test theory and item response theory;
  • acknowledge the usefulness of IRT in medical education assessment;
  • provide a basic description of item calibration and score calculation procedures in IRT;
  • perform IRT-based analyses on their own data.
