Advances in understanding the effects of early education have benefited public policy and developmental science. Although preschool has demonstrated positive effects on life-course outcomes, limitations in knowledge on program scale, subgroup differences, and dosage levels have hindered progress. We report the effects of the Child-Parent Center Education Program on indicators of well-being up to 25 years later for over 1,400 participants. This established, publicly-funded intervention begins in preschool and provides up to 6 years of service in inner-city Chicago schools. Relative to the comparison group receiving the usual services, program participation was independently linked to higher educational attainment, socioeconomic status (SES) including income, health insurance coverage as well as lower rates of justice-system involvement and substance abuse. Evidence of enduring effects was strongest for preschool, especially for males and children of high school dropouts. The positive influence of 4 or more years of service was limited primarily to education and SES. Dosage within program components was mostly unrelated to outcomes. Findings demonstrate support for the enduring effects of sustained school-based early education to the end of the third decade of life.

Participation in a school-based intervention beginning in preschool was associated with a wide range of positive outcomes. Findings provide evidence that established early education programs can have enduring effects on general well-being into adulthood.

We conducted a cost-benefit analysis of the Child-Parent Center (CPC) early childhood intervention. Using data collected up to age 26 on health and well-being, the study is the first adult economic analysis of a sustained large-scale and publicly-funded intervention. As part of the Chicago Longitudinal Study, a complete cohort of 900 low-income children who enrolled in 20 CPCs beginning at age 3 were compared to 500 well-matched low-income children who participated in the usual educational interventions for the economically disadvantaged in Chicago schools. School-age services were provided up to age 9 (third grade). Findings indicated that the three components of CPC had economic benefits in 2007 dollars that exceeded costs. The preschool program provided a total return to society of $10.83 per dollar invested (net benefits per participant of $83,708). Benefits to the public (other than program participants and families) were $7.20 per dollar invested. The primary sources of benefits were increased earnings and tax revenues, averted criminal justice system and victim costs, and savings for child welfare, special education, and grade retention. The school-age program had a societal return of $3.97 per dollar invested and a $2.11 public return. The extended intervention program (4 to 6 years of participation) had a societal return of $8.24 and public return of $5.21. Estimates were robust across a wide range of discount rates and alternative assumptions, and were consistent with the results of Monte Carlo simulations. Males, 1-year preschool participants, and children from higher risk families had greater economic benefits. Findings provide strong evidence that sustained early childhood programs can contribute to well-being for individuals and society.

This study investigated the contributions of 5 mechanisms to the effects of preschool participation in the Child-Parent Centers for 1,404 low-income children in the Chicago Longitudinal Study. Based on a matched-group design, preschool participation was associated with significantly higher rates of educational attainment and lower rates of juvenile arrest. LISREL analysis revealed that the primary mediators of effects for both outcomes were attendance in high-quality elementary schools and lower mobility (school support hypothesis), literacy skills in kindergarten and avoidance of grade retention (cognitive advantage hypothesis), and parent involvement in school and avoidance of child maltreatment (family support hypothesis). The model accounted for 58% and 79% of the preschool links with school completion and juvenile arrest, respectively. The maintenance early intervention effects are influenced by many alterable factors.

The authors investigated a comprehensive set of predictors of high school completion and years of completed education for youth in the Chicago Longitudinal Study, an ongoing investigation of over 1500 low-income, minority children who grew up on high-poverty neighborhoods. The study sample included 1286 youth for whom educational attainment could be determined by age 20. Predictors were measured from birth to high school from participant surveys and administrative records on educational and family experiences as well as demographic attributes. Results from regression analyses indicated that the model explained 30.4% of the variance in years of completed school. The model also predicted accurately 73.3% of youths' observed high school completion status and 72.6% of their high school graduation status. The strongest predictors of educational attainment were maternal educational attainment, school absences and mobility, grade retention, and youth's educational expectations. Findings indicate that students' expectation and school mobility are targets of intervention that can promote children's educational persistence.
