This report evaluates the performance of three private agencies on the school desegregation process in Boston. The Citywide Educational Coalition organized and stimulated parents to publish a newsletter. Freedom House provided the only fully equipped information center which specifically supported black parents, students and agencies by answering telephone inquiries. The Massachusetts Advocacy Center interceded in school suspension cases. The report concludes that although these agencies were inconsistent in their aims and achievements, they were not superfluous. Without these groups, desegregation would still have been accomplished; however, services and support that should have been provided by governments and by the individual school systems in order to facilitate the transition, were ultimately assumed by these private groups. These agencies filled a void left by reluctant decision makers and administrators; softened resistance to integration by providing voices of moderation; gave voice to citizens' needs; and supported and aided pro-implementation casualties of the desegregation process. Included in this report are recommendations for the 1976-77 academic year. Basic to these recommendations is the need for government support and funding of the groups which promote desegregation. Extensive appendices to this report provide data on the evaluation process, the climate and events of desegregation, and the roles and activities of pro-implementation agencies. (Author/GC)
