do child care centers benefit poor children after school entry?

Abstract

Attendance in preschool centers can yield short-term benefits for children from poor or middle-class families. Yet debate persists in Europe and the United States over whether centers yield gains of sufficient magnitude to sustain children's cognitive or social advantages as they move through primary school. We report on child care and home environments of 229 children in the US who were 2½ years of age (on average) at entry to the study. Among children attending a center at 2½ or 4½ years of age, cognitive proficiencies were significantly higher at 7½ years of age, compared with children in home-based care, after taking into account prior proficiency levels, maternal attributes, and other covariates. No relationship between center attendance and social development, positive or negative, was detected at 7½. A priori selection factors modestly helped to explain the likelihood that mothers enrolled their child in a center. But associations between center exposure and higher cognitive proficiency at age 7½ remained after controlling for selection factors and testing for omitted variables bias.
