About CLS

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.

The study is in its 20th year of operation. Besides investigating the short- and long-term effects of early childhood intervention, the study traces the scholastic and social development of participating children and the contributions of family and school practices to children's behavior. The CPC program provides educational and family support services to children from preschool to third grade. It is funded by Title I and has operated in the Chicago Public Schools since 1967 (see the CPC History Document).
