This report presents an evaluation of the Multicultural Education Demonstration Program in Pittsburgh (Pennsylvania), an effort to address racial and ethnic diversity in a middle school. The report covers the implementation of the program since its inception in May 1989 through the beginning of the 1991-92 school year. It describes the program's status and the status of six challenges it addresses: (1) respect and understanding for all groups; (2) community confidence in the school; (3) ownership of the multicultural ideal among staff, students, parents, and the community; (4) student psychosocial development; (5) enhanced student career and educational aspirations; and (6) improvement in the academic achievement of all groups. Section I provides background in the multicultural education movement and then presents the aims of the program.

It includes information from the perspective of students, staff, and parents who are participants in the model program. Section III describes current levels of program implementation and the implications of development to date for meeting the six challenges and for replication of the multicultural program in other schools.
