Carolina Abecedarian Project (ABC) and the Carolina Approach to Responsive Education (CARE), Age 21 Follow Up Study

Study Overview

Description: 

The Carolina Abecedarian (ABC) Project and the Carolina Approach to Responsive Education (CARE) projects consist of two consecutive longitudinal studies on the effectiveness of early childhood educational intervention for children at high risk for developmental delays and school failure. Combined, the two studies test the hypothesis that child care, home visit, and home school resource interventions can enhance cognitive and academic outcomes for children at risk for school failure due to factors such as poverty, low maternal IQ, or low parental education. These studies provide experimental data regarding the efficacy of child care interventions that began during early infancy and lasted until the child entered kindergarten. In addition, the data allow for tests of the efficacy of intervention during the primary grades.

Sampling Procedures: 

This project followed up on samples from two earlier longitudinal studies: the Carolina Abecedarian Project (ABC) and the Carolina Approach to Responsive Education (CARE). The ABC project recruited children born between 1972 and 1977. At entry to school, half of the children within each of the two randomized preschool groups were randomly assigned to receive a home school resource teacher program during the first three years of elementary school. Children recruited for Project CARE were born between 1978 and 1980 and randomly assigned to one of three treatment groups: child care plus home visits, home visits only, or control. All Project CARE children assigned to either the child care plus home visit or home visit only groups also received the home school resource teacher treatment during the first three years of elementary school.
