The design and implementation of a rotating class schedule which was put into effect in the Charlo High School, Charlo, Montana in September 1969 is discussed in this paper. The schedule, described in this report, consists of a 75-minute period followed by 2, 60-minute periods in the morning and 4, 45-minute afternoon periods. The program evaluation, made after the initial 3 weeks, is described; and negative and positive aspects of the rotating schedule are discussed. It is noted that the program should be a cooperative effort involving the students, the teachers, and the administration. An example of a class rotating schedule is presented. (PS)
