In 1982-83, the program evaluated here provided tutorial and supportive services to approximately 50 Spanish-speaking students of limited English proficiency (LEP) in grades 9-12 at Clara Barton High School, Brooklyn, New York. The program's main objective was to enable LEP students to function successfully in terms of language achievement and content courses, acculturation, and motivation to remain in school. Students were not scheduled for tutorial sessions but came in when they needed help and specified areas in which they most needed help. Supportive services offered by the project included services from the school's grade advisors and guidance counselors and more informal advice and encouragement from program staff. Quantitative analysis of student achievement indicates that (1) students did not meet the program's criterion for English language development, but high pretest scores limited the possible growth in this area; (2) passing rates for program students in Spring social studies and foreign language courses exceeded those for mainstream students; and (3) attendance rates did not differ significantly from the general school attendance rate. In the area of staff development, staff members attended relevant university courses. Finally, parental participation was limited because the school is not neighborhood based. (CMG)
