Evaluation of parent involvement in the following ten early childhood programs in the Philadelphia school district is presented: (1) Child Care (CC); (2) Head Start (HS); (3) Parent Nursery (PN); (4) Get Set (GS); (5) Durham Child Development Center (DCD); (6) Preschool Child Development Project (PCD); (7) Original Follow Through (OFT); (8) Follow Through Expansion (FTE); (9) Primary Skills (PS); and (10) Project Bridge (PB). Across all programs the overall level of participation was reflected in 188,966 total hours contributed by parents. Volunteer work predominated, exceeding workshop attendance by a 4 to 1 ratio in total hours. Classroom participation elicited the greatest number of volunteer hours across all programs with 81,433 hours, followed by meetings with 36,079 hours. Across all programs workshop attendance was 15,861; PN had a rate of attendance corresponding to 12.58 per child, CC, 1.34 per child, and HS, 1.12 per child. Workshops dealing with educational matters were by far the most frequently attended, followed by those concerned with growth and development, and last by those dealing with social services.
