This booklet gives a general overview of the computerized Stanford School Scheduling System (SSSS) which is designed to make scheduling less difficult for individualized programs in secondary education. Topics covered include new flexible scheduling and variable course structure designs in secondary education, the school scheduling problem, schedule construction using the SSSS, field testing of the SSSS, SSSS parameter limits, and computer system requirements. Among the advantages of the SSSS are (1) it is a technology which enables the construction of complex flexible schedules; (2) it requires precise definition of the design of each course offered in the school program, as well as the overall program design; and (3) it encourages professional personnel to explore in detail the appropriateness of different arrangements of time, class size, pupil grouping, and use of staff and facilities. The availability of technical documents and the set of programs for the SSSS written in FORTRAN IV for IBM systems 360-40, 360-50, or 360-67 is described in the final section. (TT)
