 An evaluation of Chicago Public Schools' federally funded Child Parent Centers find that for every $1 invested in the preschool program, nearly $11 is projected to return to society over the participants' lifetimes.This amount is equivalent to an 18% annual return.Head Start Program, Title I of the Elementary and Secondary Education Act (ESEA), and various state-funded pre-kindergarten programs target students from low-income families in an attempt to equal the playing field for these children before school begins.
