Arthur Reynolds describes the significance, development, and effects of preschool to 3rd grade approaches. This school reform strategy integrates services and supports transitions, thereby increasing achievement, sustaining gains, and realistically reducing achievement gaps. Evidence from the Child-Parent Center (CPC) program is reviewed to illustrate key principles, strategies, and elements. Data from the Chicago Longitudinal Study and the more recent Midwest CPC expansion show that the program is effective in enhancing the transition to school and promoting longer-term well-being.
