This study retrospectively applies aggregate scoring to the cardiology questions from a recertifying examination in general internal medicine. Three groups of experts were identified among the examinees and the remainder of the examinees were the participants (N=1887) of the study. Generalizability theory is applied to these data. (MLW)

Item response theory's (IRT) suitability for medical examination data was examined, using data on 2,000 candidates who took the 1980 and 1982 American Board of Internal Medicine Certifying Examinations. Focus was on determining whether the tests met IRT assumptions and applying one-parameter and three-parameter IRT models to the data. (TJH)
