PTC-NC presents
Enhancing Multiple Choice Tests Using Item Response Theory 


This presentation demonstrates the utility of introducing an Item Response Theory (IRT) methodology, specifically the Rasch model, to complement Classical Test Theory (CTT) in the development and calibration of multiple-choice exams. Given the development and advances within IRT-methods and the prevalence of CTT in test development efforts conducted throughout the State, this presentation aims to demonstrate how modern IRT-based methods could be used alongside CTT to address current limitations in practice and improve the overall psychometric quality of multiple-choice exams. This presentation will show data from two prior administrations of multiple-choice exams to demonstrate how, through a consideration of examinee “ability”, the Rasch Model can: provide various sources of validity evidence, localize exam measurement precision, optimize exam length through eliminating redundant items, and equate test forms. The presenter will then draw some conclusions on the Rasch model’s feasibility, comparative ease of use to CTT, and expected challenges in implementation.
