This report describes, presents demographic data for, and evaluates the effectiveness of a bilingual education program for 344 Hispanic students in South Bronx High School, New York. The program's goals include improvement of students' English and Spanish language skills, reinforcement of Hispanic cultural values and knowledge, enhancement of self esteem, and orientation to the culture and values that students confront in the United States. The instructional component of the program stresses early and gradual transition to a mainstream, English language program. This objective is pursued through intensive English as a second language instruction, as well as bilingual classes in science, mathematics, and social studies. The noninstructional component of the program includes emphases on curriculum and materials development, supportive services, staff development, parental and community involvement, and students' affective domain. Evaluations of students' academic performance indicate that in 1980-81, program participants who received instruction in English had higher pass rates than did those who received instruction in Spanish. This report provides several recommendations for more effective implementation of the bilingual program. (GC)
