This report evaluates a three-year-demonstration program in child advocacy, created as part of existing Head Start Parent-Child Centers to meet the needs of children under 5 and their families. Local services were integrated and new services created in a variety of areas (health, housing, education and welfare) using a primarily paraprofessional untrained staff. Evaluation data were collected from on-site interviews with Advocacy Component (AC) coordinators and staff members, community agency administrators, and randomly selected families served by the ACs as well as from monthly statistical reports on contacts, referrals, staff changes, etc. The report is divided into eight sections (1) the history and development of the AC program; (2) initial objectives and their changes; (3) activities on behalf of individual families and the relationships between ACs and the families served (including AC population characteristics); (4) family education efforts (e.g., workshops, meetings); (5) agency coordination efforts; (6) staffing patterns, staff functions, training and turnover; (7) the functional cost data analysis; and (8) conclusions. Generally, the ACs are thought to have accomplished considerable work in their communities and on behalf of individual families, but their achievements were found to fall short of the nine national goals originally set for the program.
