The purpose of this economic impact report is to assess the estimated benefits and costs of investing in high quality, state-funded preschool programs for three- and four-year-old Hoosier children. The report evaluates the landscape of early childhood education in Indiana and demonstrates how an expanded state role in funding high quality Early Childhood Education may benefit Hoosier families and taxpayers. The report then surveys the best available Early Childhood Education research to estimate the return on investment associated with adopting a high quality program. (author abstract)
