This study, conducted by the Bernard Van Leer Foundation Project for Early Childhood Education (PECE), presents the results of a survey which was carried out to identify home deficits in socioeconomically disadvantaged children's preparation for schooling. The study was conducted in Jamaica during July, August, and September, 1970, and was restricted to households with 4- to 5-year-old children enrolled in the Basic Schools in Kingston, St. Andrew, St. Thomas, and Portland parishes. Section I, titled, "Deficit Hypothesis," gives a broad introduction to the factors which are indicative of home deficits of typical Basic School children as seen through the eyes of the PECE staff. Included in the introduction are descriptions of the neighborhood, housing and family size, household employment and earning, the use of rewards and punishment by parents, and parents' level of education. The findings of the study are presented in tabular form in Section II. No statistical operations have been performed on the data. (Author/MP)
