The report by the Task Force on Children Out of School describes practices and procedures of exclusion which prohibit a minimum of 4,000 school age children from attending the Boston public schools. Children who are culturally different, physically different (both handicapped and pregnant), mentally handicapped, and emotionally disturbed are discussed as primary groups of school exclusion. Examples of misplaced priorities in Boston's school policies are presented in areas of the School Department practices, school counselors and attendance officers, mental health services, and general administrative responses to children's needs. Specific recommendations to eliminate conditions of school exclusions are provided. Appendixes cite general laws relating to education, examples of school programs in other cities, statistical data from the survey of children out of school, and names of persons interviewed during the study.
