Ongoing comprehensive evidence reviews of the Prenatal-to-3 Policy Clearinghouse

The Prenatal-to-3 Policy Clearinghouse provides analysis of the evidence on state policies and strategies that intend to strengthen outcomes for infants, toddlers, and their families. The policies and strategies included in the Clearinghouse reflect the evidence reviews conducted to date. Our reviews of the available evidence are ongoing, and policies and strategies will be added to the Clearinghouse on a continual basis.

The process of identifying specific policies aligned with the 8 science-based PN-3 goals described in the Clearinghouse is also ongoing. As we identify policies, we are conducting a careful review of each to evaluate the rigor and strength of both the theory of change and the evidence base to draw conclusions about each policy’s effectiveness for supporting children and families and building equity in the critical prenatal-to-3 period.

We welcome feedback and recommendations on additional state-level policies and strategies to consider for review. Please contact us with your comments and requests.
