Project Adelante provided instruction in English as a second language (ESL), as well as bilingual instruction in social studies, mathematics, and science to 230 students of limited English proficiency at William H. Taft High Schol, Bronx, New York City. One of the program's major goals was to expedite the acquisition and use of English language skills necessary for entry into mainstream courses. Quantitative analysis of student achievement during the second year of Project Adelante indicates that: (1) on the average, students failed to meet program objectives in ESL and Spanish reading; (2) from 54 to 61 percent of the program students enrolled in mainstream mathematics courses passed teacher made exams; (3) 62 to 67 percent of the students passed the bilingual mathematics courses; (4) a higher percentage of program students passed mainstream science courses than bilingual science courses; (5) in social studies, similar passing rates were noted in the mainstream and the bilingual courses; and (6) the overall attendance rate of program students exceeded that of the school as a whole by 26 percent. Program evaluation also resulted in a number of recommendations regarding administrative reorganization to increase communication among teachers, evaluation of course offerings, increased parent participation, and review and evaluation of instructional materials.
