The Louis D. Brandeis High School Bilingual Program provides English and Spanish language instruction, academic courses, and supportive services for Spanish speaking students of limited English proficiency. This report describes the program as it was implemented in 1980-81. The program description includes background and context; student characteristics; organization and funding; faculty relations; the instructional component, consisting of English as a Second Language, native language instruction, mathematics, science, and social studies; curriculum development activities; counseling services; staff development; parent involvement; and evaluation. Evaluation results indicate that: (1) students had positive attitudes toward the program; (2) program attendance rates were higher than the school's attendance rates; (3) several program participants received academic honors; and (4) in general, moderate to highly significant gains were made in English syntax and language fluency, native language arts, mathematics, science, and social studies, although some students failed to reach the program achievement criteria. Recommendations for program improvement are presented. (MJL)
