University admission exams belong to so-called high-stakes tests, i.e. tests with important consequences for the exam taker. Given the importance of the admission process for the applicant and the institution, routine evaluation of the admission tests and their items is desirable.
In this work, we introduce a quick and efficient methodology and on-line tool for semi-real-time evaluation of admission exams and their items based on classical test theory (CTT) and item response theory (IRT) models. We generalize some of the traditional item analysis concepts to tailor them for specific purposes of the admission test.
On example of medical school admission test we demonstrate how R-based web application may simplify admissions evaluation work-flow and may guarantee quick accessibility of the psychometric measures. We conclude that the presented tool is convenient for analysis of any admission or educational test in general.
