Project LAUNCH (Linking Actions for Unmet Needs in Children's Health) is a federal grant program administered by the Substance Abuse and Mental Health Services Administration (SAMHSA). Its objective is to promote the social-emotional, cognitive, physical, and behavioral health of children from birth to 8 years of age. The findings of the Cross-Site Evaluation of Project LAUNCH are presented in two volumes. This volume presents results of the process evaluation. The process evaluation uses descriptive analysis to summarize the extent to which the LAUNCH grantees in the first three cohorts succeeded in addressing three goals: improvements to the local child services system in the LAUNCH communities, improvements to the state child services system, and enhancements to child and family services in LAUNCH-funded pilot communities.
