This study consists of a review of the literature, a discussion of some of the vital questions concerning the year-round school, and a bibliography. Discussed are (1) quarter schedules of various types and their applications to school calendars, (2) transitions to quarter schedules from conventional schedules, (3) teacher and staff assignments, (4) building capacities, and (5) curriculum and scheduling. These issues are presented and discussed, and various methods of solving problems are provided as a guide for those districts planning to conduct studies of the year-round school, necessarily within the context of their own philosophies and needs.
