Effects of the alternative medical curriculum at the Hannover Medical School on length of study and academic success.

Objective: The model curriculum HannibaL (Hannoversche integrierter berufsorientierter und adaptiver Lehrplan) differs significantly from other medical study programs in Germany in terms of its structure with which, among other factors, the Hannover Medical School (MHH) saw an opportunity to positively influence the length of study. We investigate how the length of medical study is influenced by the curriculum's structure and whether this has any impact on academic success. Methods: We use data from over 2,500 students who studied medicine at MHH between 2011 and 2021. We measure study time as the number of years which pass until completion of the respective study phases and academic success as the grades achieved on final exams. Results: Since they more often fail or postpone exams, students admitted based on special quotas (VQ) or a waiting list (WQ) need significantly more time to complete the first study phase (M1) compared to students who were admitted based on a selection process (AdH) or who belong to the "best school graduates" quota (AQ) because they earned the highest scores on the final secondary school exam. Yet, students from all admission groups reach the written state exam (M2) almost simultaneously. In HannibaL, WQ and VQ manage to catch up on delays from M1 with no negative impact on success in M2. In general, however, VQ and WQ achieve lower grades and drop out more often than students from AQ and AdH. Discussion: In the regular curriculum, students can only proceed with their studies once M1 has been entirely completed. HannibaL, on the other hand, allows for the catching up of delays from the first two years of study by integrating both study phases. The curricular structure thus accommodates students with lower academic performance who accumulate delays early on in their studies. By contrast, delays in the AQ and AdH groups arise during the second phase of study (M2).
