The Chicago Effective Schools Project (CESP) is a demonstration program, involving racially isolated schools (Black and Hispanic), designed to provide equal educational opportunity and excellent school programs in schools that cannot be desegregated. This report describes the program as it was implemented in fiscal years 1982 and 1983. The program description includes a brief review of the effective schools literature; major evaluation variables; program design and implementation; and program implementation in Hispanic and bilingual schools. Evaluation results summarized indicate (1) that the program was generally conducted as intended; (2) student achievement improved for most grade levels, and 20 of the CESP schools moved upward in the ranking of the Chicago elementary public schools; (3) most CESP students and their parents had positive attitudes toward the program, although a significant minority were ambivalent or negative toward certain of its aspects; (4) few students understood the Chicago Mastery Learning units; and (5) although there was some staff disagreement about the provision of bilingual services, bilingual students expressed positive attitudes about the program. Recommendations for program improvement are presented. (CJM)
