The Bilingual-Bicultural Program at DeWitt Clinton High School, Bronx, New York, was designed to provide support services to students with problems in reading and writing skills, and in linguistic, academic, and classroom adjustment. The program offered instruction in English as a Second language (ESL), Spanish for native speakers, Spanish as a second language (SSL), and bicultural content area courses to 214 students in 1982. An evaluation of the program, based on students' achievement in English language development, mastery of their native language, mathematics, social studies, and science showed: (1) levels 9 and 10 students demonstrated a moderate improvement in English, while level 11 students showed a slight decline; (2) the performance of students at all levels and grades improved in Spanish; (3) level 11 students showed a moderate improvement in mathematics, while level 9 and 10 students showed a slight decline; (4) the majority of the students who received instruction in English did well in teacher made tests in mathematics, science, social studies, and native language; and (5) student attendance objectives for the program were met. Recruitment of more bilingual personnel was recommended. Statistical data on staff development is appended to this evaluation report. Also appended are lists of services and cultural activities for bilingual students, and records of parental involvement. (AOS)
