Project "At Your Service" at Park West High School in New York City, is a basic bilingual secondary education program for Spanish speaking ninth to twelfth grade students with limited English proficiency. In 1981-82, the program provided bilingual instructional and supportive services, and opportunities to participate in career and culturally related activities, for 200 Hispanic students. Other program activities included staff development and activities geared toward parent involvement in the program. This report describes the program context, organization, participants, activities, and evaluation. Evaluation results indicate that, in general: (1) students surpassed the criterion objective for English syntax; (2) over 70 percent of the participants passed teacher-made tests in Spanish language courses; (3) participants' mean scores on tests in English, science, mathematics, and social studies exceeded the scores of mainstream students; and (4) the participants' attendance rate was higher than the school-wide attendance rate. Recommendations for program improvement are presented. (MJL)
