The Samuel Gompers High School (Brooklyn, New York) Bilingual Mini-School program was assessed during the 1985-86 school year, its final year of a three-year funding cycle. This evaluation is divided into the following parts: (1) description of program, including organizational personnel; (2) student characteristics; (3) findings; (4) conclusions and recommendations; and (5) appendix describing the tests used. The program provided instruction in English as a second language (ESL); native language arts; and bilingual instruction in mathematics, science, and social studies to 104 Spanish-speaking students of limited English proficiency. In addition, program students were enrolled in several specialized mainstream vocational courses. The program sought to help students improve their English competence and meet academic requirements for a high school diploma in as short a time as possible. Program objectives were assessed in English language development, mathematics, science, social studies, and Spanish. Analysis of data showed modest success in achieving the instructional and non-instructional objectives. Students' passing rate in the ESL component improved from 62 percent in the fall to 79 percent in the spring. The overall passing rate in mathematics, science and social studies, at 67 percent, surpassed the proposed objective in this area. (PS)
