This report documents the evaluation of the Bilingual Mathematics and Science Achievement Program (Project BMSA) for students of limited English proficiency. The bilingual program was designed to provide intensive mathematics and science instruction, using mastery level concepts, in the native language and to incorporate mathematics and science concepts and themes into English language classes. The project provided training for teachers of students of limited English proficiency by offering workshops in science and mathematics and developed curriculum materials for both subjects. To evaluate the program, OREA interviewed project coordinators, observed a science workshop, and collected data on participants' ratings of the workshops. This document summarizes the results of an evaluation of the staff development aspect of the program. The peer teaching aspect of the program (Project SUMA) is briefly mentioned. A brief overview and history of the program, a summary of the evaluation methodology, and a summary of the evaluation findings of the evaluation of the mathematics and science comonents are presented.
