This report describes the evolving activities of an educational intervention program which is composed of (1) a comprehensive early childhood program for children from infancy through age 6; (2) a subsequent elementary program offering continuity of developmental support; (3) day care services, including after-school activities for school-age children; (4) a broad research program in child development and education; (5) a comprehensive array of supportive family services; and (6) preservice and inservice staff and student training programs. New developments and areas identified as needing change are discussed in relation to each aspect of the program. Discussion of the project's research activities includes an overall view of the research program and more detailed reports on Project AWARE (a human relations program for the primary grades) and Project LEAP (an experimental language training curriculum for 2- and 3-year-old day care children). The preservice and inservice training programs for staff and students are described. In addition, a consideration of future educational and research plans is included. Appendices, comprising two thirds of the report, include (1) essays describing the program and its underlying principles; (2) tables showing the program's testing schedule; (3) materials used for home intervention (approximately one-fourth of the study); and (4) papers concerning the powerful position of day care today, the effects of day care on children, and aspects of research programs involving the disadvantaged.
