This program operates on the assumption that exposure of 3- and 4-year-old children to a structured basic skills oriented program with continuity will substantially increase the contributions of school-related factors to educational achievement and adjustments, and to a large extent erase the gap between less advantaged children and their more advantaged counterparts. Program objectives, administration, facilities, instruction, supportive services, and parental involvement are described. The preschool, kindergarten, and primary programs, along with curriculum materials used are described. Data from a comprehensive longitudinal evaluation design indicates that growth in readiness and achievement tends to be uniform across classrooms, grades, and centers. The data are considered to show that this program operates in a manner that uniformly raises the readiness and achievement levels of all children. Several components of program success--among them early intervention and the need for consistency--are identified. A brief discussion on ripple effect resulting from the program's impact on the community, and a followup of program graduates, is included. (Author/AM)
