This paper describes Head Start services to parents and families involved in the Head Start program, what the program impact has been on these families, and the goals, services, and accomplishments of other family-focused Head Start programs. There are 14 sections, most of them brief. The sections discuss sources of data information, Project Head Start Performance Standards, and ways parents contribute to the functioning of the program as decision-makers, home educators and employees. Program-community relations, service benefits to handicapped children and their parents, and gains parents receive from participating in the program are noted. Also described briefly are post Head Start parent activities in the school and community. An extensive review of the historical impact of the program on parents and families is also presented and documented with research study results. The last section focuses on 3 special Head Start demonstration programs (Parent Child Centers, Home Start, and the Child and Family Resource Program). (SE)
