Equating Scores on Large-Scale Medical Performance Assessments: Practical Issues and Solutions

Sun, April 15, 8:15 to 9:45am, The Parker, Floor: Third Floor, Azekka Room

Session Type: Symposium

Abstract

Testing programs routinely need to develop multiple forms of exams to minimize item/case exposure and mitigate potential security breaches.

Despite best efforts to develop exams that are comparable content wise and psychometrically, test forms will invariably differ in difficulty.

Equating is the statistical process with which scores on different examinations are adjusted to account for the relative difficulty of each form.

However, equating performance assessment scores poses a number of challenges.

The goal of this session is to illustrate several practical equating issues for scores on complex medical education performance assessments.

The present symposium will provide real-world examples on how to equate scores on complex performance assessments to ultimately produce fair, transparent and defensible measures for all candidates.
