Early in 1982 the Seattle (Washington) School Board organized a seminar on school effectiveness in Seattle. The seminar group, including teachers, administrators, a community representative, and a school board member, looked at relevant research and considered testimony by community groups, individuals, teachers, and students on school effectiveness. This report is the product of that process. It begins with a brief summary of research on effective schools. A short definition of effective schools is offered, describing them as those in which all students master basic skills, seek academic excellence in all subjects, and demonstrate achievement through systematic testing. The report then lists 12 characteristics that are necessary for effective schools in Seattle, ranging from clear goals to parent and community involvement. The next chapter presents a summary of problems identified by the seminar in 11 areas in Seattle schools, such as staff dedication, goals, time on task, and communication. Based on the problems identified, the report lists general and specific recommendations for making Seattle schools more effective. The roles of all participants in the Seattle schools are then delineated. A list of existing policies and policy recommendations relating to effective schools concludes the report. (Author/JM)
