Abstract
Multiple Choice testing (MCT) is one of the most popular approaches to the assessment of knowledge acquisition. Preparing a MCT is complex; however, its metric quality (in terms of difficulty, discrimination capacity, or distractors effectiveness) is not usually assessed. “Item Response Theory" (IRT) is a statistical approach that may assist when evaluating the quality of a MCT. IRT lets to estimate indices that may be used later as a way to improve thequality of the assessment. The aim of this work was to present the results of a teaching innovation project in which the IRT was employed to analyze the MCT used during the last 3 courses in the subject «Psychological Evaluation» (Degree in Speech Therapy). Results suggested that a significant proportion of the questions analyzed presented certain limitations, such as the excessive prevalence of easy items (between 45%-67.5%) or ineffective distractors (between 17.5%-26.6%). Yet, these issues did not impact the discrimination capacity of the MCT. These results serve as a basis for proposing initiatives to improve evaluations through MCT, which ultimately will result in a fairer and more balanced evaluation of the students of the subject.
