An executive summary of findings, this is the first volume of the Third Monitoring Report on Boston Public School Desegregation. The report, covering Boston Public Schools operations from December 1983 through May 1984, was filed by the Massachusetts Board of Education and Commissioner of Education under Orders of Disengagement entered at Federal District Court on December 23, 1982. This volume has twelve main sections which correspond to each of the twelve monitoring areas enumerated in the Orders of Disengagement: student assignments, staff, special desegregation measures, special education, bilingual education, vocational and occupational education, transportation, facilities, safety and security, student discipline, institutional pairings, and parent and student organizations. Each section contains a description of objectives, procedures, findings and recommendations, as well as a summary of previous findings to provide a gauge of progress during the period of State Board monitoring. Two final sections briefly discuss the progress of disputes during the covered monitoring period and procedures for initiating modifications of existing orders. (KH)
