The Follow Through Expansion Program involved 46 schools in all eight districts of Philadelphia, Pa. The program was instituted at the kindergarten level in March, 1975. Five model options were proposed for implementation on the basis of previous evaluation findings regarding the original Follow Through Program in Philadelphia. Of these, four were selected by the participating schools: Option 1: a local adaption of the Behavior Analysis model, Option 2: a Behavior Analysis/ Bank Street combination, Option 3: a Behavior Analysis/Bilingual combination not selected by the participating schools, Option 4: a local adaption of the Bank Street model, and Option 5: a Bank Street/ Bilingual combination. Pre-program questionnaires were completed by principals, resource teachers, teachers, and aides, and yielded background information on program personnel as well as pre-program attitudes. The majority of principals indicated that they were satisfied with the model assigned to them and that they expected Follow Through to have a strong effect on pupil achievement, parent participation, staff development and the motivation of instructional personnel. Sixty-seven percent of the teachers also evidenced positive reactions to the news of the expansion program. Option 4 teachers elicited the highest percentage of positive responses and Option 2 the lowest. Aides indicated increased clarity after training but somewhat lower enthusiasm, possibly due to previous training which emphasized a different instructional orientation at the kindergarten level.
