AmeriCorps has invested significant resources in supporting implementation of interventions designed to improve lives and strengthen communities. AmeriCorps also invests in evaluating the effectiveness of these interventions and supporting the scaling of those that have evidence of being effective to serve new communities or populations. Using information gathered through the Scaling Evidence-Based Models project process study, this report presents a case study of Parent Possible, a CNCS grantee implementing the Home Instruction for Parents of Preschool Youngsters (HIPPY) intervention in Colorado. During home visits, HIPPY seeks to engage the parents of young children with activities designed to improve children’s development in reading, math, science, motor, and language skills. This case study provides insights about how Parent Possible is scaling HIPPY, as well as the factors that appear to facilitate and hinder scaling.
