The final report of a five-year federally-funded bilingual education program in four schools of the the Sunnyside School District in Tucson, Arizona, is presented. The following areas are addressed: (1) student enrollment patterns, (2) the instructional program for kindergarten through fifth grade and its development, (3) staff development efforts through a variety of organizations, (4) parent involvement and training workshops through an advisory council and other community organizations, (5) the design of the program's evaluation, and (6) statistical results. Absence of data on entry level skills and changes in record keeping inhibit valid comparisons between groups, and no long-term impact conclusion is reached. (MSE)
