The Eastern District High School bilingual-bicultural program served 367 Hispanic students in grades 9 through 12. Students received instruction in English as a Second Language and/or reading English, native language arts, math, science, and social studies. Students were mainstreamed for art, music, physical education, and health. Elective courses were also available. Non-instructional program components included staff development, curriculum development, extra-curricular activities, parental and community involvement, and affective services. Academic achievement of students was measured by standardized and teacher developed tests. Students demonstrated gains in English reading, native language arts, and mathematics at all grade levels. Achievement in other areas was mixed. Evaluators observed program operation and determined that it was well implemented and successful. Recommendations for future program implementation are included as well as tables of achievement data. (MK)
