The interim findings of a citizen commission charged with monitoring the implementation of the Chicago (Illinois) Public School desegregation plan are presented. The first of four sections of the report describes the context for the monitoring effort, including legal suits against the school systems in the 1960s and the events and legal decisions leading to the desegregation plan and the formation of the district's Monitoring Commission for Desegregation Implementation. The second section describes the monitoring experiences including the targeted schools, the organization and membership of the commission, the magnet schools and transfer options, other educational components, the affirmative action and staff development efforts, and reflections on the first year of the monitoring effort. The third section describes the monitoring strategy and includes an interim report from each of the commission's subcommittees along with the methodologies and findings. The findings indicate that although some progress was made in reading achievement scores, those scores still lag behind comparison and citywide schools. In addition, the commission found that many problems persist in desegregation implementation. The fourth section offers an overview of the current status of the implementation and in particular the constitutional vulnerability of the plan due to the lack of implementation. One table is included. (JB)
