The Demonstration Bilingual Enrichment College Preparatory Program at Louis D. Brandeis High School in New York City is designed to address the needs of the "academically more able" student with limited English proficiency. The program supplements the school's existing services for 120 Spanish-dominant students, and offers instructional programs in cultural activities, special mathematics and English courses geared to college entrance examinations, and college advisement. An evaluation of the program's first year, based on student achievement in English language development and growth in their mastery of their native language, mathematics, social studies, and science, shows that (1) students mastered 1.3 objectives per month of instruction in English as a second language, but fell short of the program objective of 1.5 per month; (2) students made statistically and educationally significant gains in reading; (3) most of the students passed teacher-made examinations in mathematics in courses taught in both English and Spanish; (4) all 29 students who took Spanish language courses passed; (5) the majority of students who took teacher-made tests on science courses in English and Spanish passed; (6) the program objective for social studies was maintained; and (7) the program students' attendance surpassed the school-wide attendance average. Recommendations for further improvement of the program are included in the evaluation. (AOS)
