The Achievement through Bilingual Education Project (ABLE) served 360 Hispanic and Italian students in grades 9-12 in the Bronx, New York. Students received instruction in English as a Second Language, native language arts, and content areas (science, social studies, and mathematics) in their native languages. Additional program components included staff development, parental involvement, curriculum development, and supportive services. Program evaluation was completed using norm and criterion referenced tests of student achievement and evaluator observations. Findings indicated that (1) 47-60% of English as a Second Language goals were achieved by Spanish speaking students, (2) under 40% of all students showed gains in receptive and expressive English fluency, (3) all students made significant gains in native language reading, (4) most groups of ABLE students achieved the criterion in mathematics, social studies, and science. Project ABLE students surpassed school wide attendance rates. All additional program components except supportive services were found to be effective. Recommendations for future program implementation are included in this report. (MK)
