This report summarizes the response of a monitoring commission to the 1983-84 evaluation of the implementation of the Student Assignment Plan (SAP), that is part of a court-mandated school desegregation plan in Chicago (Illinois). Under the SAP, the Board of Education was required to ensure that all schools have at least 30 percent minority enrollment and that the school system achieve a desegregation index of at least 2.0 (the total enrollment in integrated and desegregated schools must be at least twice the number of white students available for such schools) by October 1983. A further requirement was that the stability of the integrated schools be maintained. The board achieved these objectives. The following major achievements are presented: (1) all but eight of the 32 schools that had at least 70 percent white enrollments prior to the SAP had enrollments that were at least 35 percent minority after SAP implementation; (2) the system desegregation index increased from 1.59 in 1981 to 2.15 in 1983; and (3) the number of stably integrated schools increased. Statistical data are presented in seven tables. A list of schools by Student Desegregation Plan category, a review of the text of the 1983-84 evaluation report, and comments on 102 of the designated schools referred to in the school-by-school analysis are appended.
