As a result of the revision of Museum Law Enforcement Rules, the subjects that must be completed to acquire the curator qualification have changed significantly since April 2012, which constitutes a major change in the history of this qualification. To cope with this change, we integrated the curator qualification specific programs of each faculty into a new course for students of all universities. In this paper, through statistical data analysis, we examined the impact of this change on attendance trends, including the term system newly adopted by Hiroshima University. Before and after the transition to the new course, the number of program registrants and qualifications greatly decreased, and the acquisition rate has also declined significantly. These phenomena were not based on changes in specific faculties or fields, but are common to all faculties subject to program registration during the old course. Through this analysis, we presumed that several factors, such as the great increase in the required number of credits, the change to the program for the whole school, and the change from a two-semester system to the four-semester system, were all interrelated to each other, which make it difficult to achieve both specialized and curator qualifications.
