The working situation of museum staff members who were originally employed as school teachers was investigated by sending questionnaires to prefectural museums as well as municipal ones in ordinance-designated cities. Such staff members are working in about half of the target museums. More than half of the teachers are planning to return to schools in three to five years, but other are planning to stay longer. In about 40% of the museums, teachers’ duties are specialized in dealing with school pupils and group visitors. The teachers’ specializations are mainly social studies, science, and art. In some cases, teachers of Japanese language work as generalists in partnerships with schools.
