The Students of Limited English Proficiency (SLEP) program of the Honolulu School District (Hawaii) is designed to help the large number of limited-English-speaking immigrants adjust to the American culture in the Hawaiian setting by acquiring basic communication skills for regular classroom participation and school activities. The program is implemented in 54 schools with over 60 permanent teachers, 10 educational assistants, and over 80 part-time teachers. Students are selected for participation and exit based on language dominance and proficiency ratings. Program components include: (1) a whole language approach emphasizing communication skills; (2) a comprehensive database containing achievement status and diagnostic data, norm-referenced, criterion-referenced, and non-test; (3) a program implementation checklist and quality control system; (4) an extensive staff development program; and (5) a survival skills segment for newly-arrived immigrants. Specific learner objectives include: making significant gains in oral language, reading, language arts, and mathematics; adjusting to school and community, and exiting the program at the 25th percentile or higher on a standardized achievement test. Evaluation of the program began only in 1985, with an extensive effort to develop a longitudinal database for student tracking, to initiate a quality monitoring process, and to implement systematic program evaluation.
