Part of a series of various Model Programs which informs educators about successful ongoing programs, the booklet describes the Project Early Push in Buffalo, New York, a preschool program for disadvantaged 4-year-olds which has been operating since 1966. The program provides experiences which are basic to later reading success and which are usually missing in traditional preschool environments. Specific objectives include: nurturing a healthy self-concept; improving perceptual, discriminatory, labeling, and concept-building abilities; enlarging understanding of the environment; encouraging self-expression; developing body coordination; and encouraging interaction with others. Distinguishing characteristics of Project Early Push include small classes arranged into several interest centers, a relatively unstructured curriculum, extensive field trips, intensive parental participation, and regularly scheduled inservice training. By the 1970-71 academic year the program had expanded to include 22 schools. Evaluation data have shown consistent gains in IQ for the project children. (LH)
