Chicago Child-Parent Center Program

The Chicago Longitudinal Study is a federally-funded investigation of the effects of an early and extensive childhood intervention in central-city Chicago called the Child-Parent Center (CPC) Program. The study began in 1986 to investigate the effects of government-funded kindergarten programs for 1,539 children in the Chicago Public Schools.

Harvard Study

The research illustrated in this chart was conducted by The Center on the Developing Child, which indicates that children who attend preschool are already ahead in early reading and math skills by the time they enter kindergarten.

The Center on the Developing Child was founded in 2006 on the belief that the vitality and sustainability of any society depend on the extent to which it provides opportunities early in life for all children to achieve their full potential and engage in responsible and productive citizenship.
