The Prenatal-to-3 State Policy Roadmap is an annual guide for each state to: Assess the wellbeing of its infants and toddlers and prioritize state PN-3 policy goals; Identify the evidence-based policy solutions proven to impact PN-3 policy goals; Monitor states’ adoption and implementation of the 11 effective Roadmap policies and strategies; Track the impact that policy changes have on improving the wellbeing of children and families and reducing disparities between racial and ethnic groups. In this Roadmap, we provide a summary of the progress that states have made over the last year toward full and equitable implementation of the 11 effective policies and strategies. The Roadmap also includes demographic characteristics of infants and toddlers across the U.S., and for each state, as well as a set of 20 outcome measures that illustrate how the wellbeing of children and families varies across states.
