The design of the 1969-70 Parent Interview (PI) survey specified that interviews be taken with the parents of children in Follow Through classes and with those of children in comparison classes of non-Follow Through children. A total of 14,833 interviews were conducted between January and March 1970 by the National Opinion Research Center in 49 communities with 67 Follow Through projects under 20 sponsors. Within the overall evalution, the PI survey served four main purposes: to examine the comparability of Follow Through and Non-Follow Through children; to determine the effectiveness of Follow Through for different demographic subgroups; to investigate parent attitudes and actions as mediators of the effectiveness of school programs; and to measure parent awareness of, participation in, and satisfaction with Follow Through. This report seeks to evaluate levels of parent involvement by comparisons of Follow Through and non-Follow Through parents, holding constant the levels of poverty and aggregating over all sponsors and grade levels. The remainder of the report is devoted to analysis and interpretation of data relating to selected measures of parent awareness, participation, influence, and satisfaction. (Author/MV)
