Project E.T.B.B.S., a bilingual education program designed to accelerate the transition to English usage among Spanish-speaking high school students of limited English proficiency, is described in this report. As implemented in 1980-81, the project provided instruction in English as a second language, native language instruction, bilingual education in academic subject areas, and guidance to 197 Hispanic students in grades nine through twelve. The report. describes program goals and organization; participant characteristics; student placement; instructional services; non-instructional program components such as curriculum and staff development, guidance/supportive services and community involvement; program implementation; and program evaluation. Evaluation results indicate that: (1) students mastered English syntax objectives in accordance with program goals; (2) on the average, students demonstrated native language reading achievement gains; (3) the criterion objective of a 65 percent passing rate was generally met in science and social studies but not in mathematics, native language arts, business education, practical arts, and music; and (4) program participants had higher attendance rates than the school as a whole. The report suggests that the program might be improved through integration of the project within the total school program and through increased staff development efforts. (Author/MJL)
