This study, based primarily on the experience of Seattle, Washington, deals with the application of the systems approach to educational planning. Section 1 defines and describes the concept of a system and the systems approach, and gives a general introduction to the use of systems analysis. Section 2 describes the development and use of the systems approach by the Seattle School District, with particular attention given to the process of planning for its use. In the third section, planning theory and the administrator's role receive attention; topics covered include the meaning of systems planning, dimensions of a plan, the planning process, and categories of educational plans. The final section discusses organization and procedures for planning, covering such topics as functions of an Instructional Development Council, origin of ideas and routing of plans for instructional improvement, improvement of management, authorization for planning, parts of a plan, integration of planning, and implementation of plans. The study ends by suggesting where interested school administrators can seek assistance in developing a systems approach to educational planning. (TT)
