Since World War II there has been a "revolutionary" increase in nonparental preschool-age child care. However, the effects of nonparental preschool care remains illusive. In an effort to address some of the limitations of previous research, seven different types of preschool-age care were statistically analyzed. Survey research and available data were gathered on 456 students in a large mid-south metropolitan area. Academic performance was measured by intelligence test scores and report card spelling grades from the sample children's third grade permanent record file. School behavior was measured by the child's conduct score over several years. Fourteen background conditions served as controls.
