The pass limit is determined by standard setting according to the scientifically accepted Angoff method. This is based on the content of each individual question; using the borderline concept, an accepted (credible) standard is determined by the examination board, which is independent of the candidate population. To ensure a constant level of difficulty, each examination is anchored to the questions of previous years. This is possible by reusing questions whose p and r values are known, using a probabilistic comparison model (Rasch items response theory). To ensure a clear reference value for data comparability, an analysis is carried out for a defined reference population as well as the usual overall analysis. 

Analysis and statistical/technical processing are ensured by cooperation with UCAN Heidelberg. The UCAN (Umbrella Consortium for Assessment Networks) is integrated in the Institute for Communication and Assessment Research and in the competence centre for examinations in medicine in the Medical Faculty Heidelberg, one of the world’s biggest and leading organisations for medical examinations.
