This report of the Committee for Economic Development focuses on findings which indicate that while American schools have succeeded with middle and upper income youth, they have commonly failed with educating disadvantaged urban youths. The report deals mainly with three groups of urban disadvantaged -- blacks, Mexican-Americans, and Puerto Ricans. Chapters in the report deal with school environment, preschool education, vocational education, teachers and educational facilities, accountability and local control, financial resources, and research and development.
