This report describes, provides demographic data for, and evaluates the success of a Spanish bilingual/bicultural education program carried out at Bushwick High School, Brooklyn, New York. The program, which served 254 students in grades 9 through 11 in 1980-81, emphasizes the attainment of minimum competency in basic skills. Participants receive instruction in Spanish language and culture; bilingual instruction in science, social studies, and math; and English as a second language and English reading classes. The bilingual program participants also take mainstream classes in art, music, physical education, and, as their proficiency allows, industrial arts and business. The noninstructional aspect of the program includes components on curriculum development, supportive services, staff development, parental and community involvement, and administration and supervision. For the 1980-81 school year, program participants' attendance, performance, and achievement either equalled or surpassed those of the general school population, a finding which is said to relate to high staff competence and morale and good program design. A number of recommendations for program improvement are offered in the report. (GC)
