The effects of a parent education program on knowledge, attitudes, and overt behavior of parents and self-concepts of their children were studied. Three randomized groups of fourth grade children and their respective parents comprised the experimental, placebo, and control groups. After the parents in the experimental group received parent education, several types of data were obtained. Analyses of variance revealed that the experimental parents manifested significantly greater knowledge, but they showed no significant difference in overt behavior. The children in the experimental group were significantly different from the other groups in perceiving themselves as doing well in school, being happy, and being satisfied with themselves as they are. It is suggested that this particular parent education program is associated with changing the behavior of parents and their children.Professional workers who are theoretically or practically interested in parent education face a difficulty problem, that of conducting experimental research which will evaluate the effectiveness of parent education in achieving its aims. Brim (2), in his definitive review of the literature in this area, affrms that the issue of how effective parent education is in changing parents or children remains unresolved at present.In the absence of conclusive evidence, parent educators continue to debate whether or not important changes in adult behavior occur as a result of parent education. Some point out that it is unreasonable to expect that participating in parent education discussion groups weekly for a short period, reading a pamphlet, or being counseled by a pediatrician during a monthly visit can exert any important influence on how a parent interacts with his child. However, other professionals working in the field believe that educational programs do produce changes, al-
