New America has been running a learning cohort known as the Early Care and Education (ECE) Implementation Working Group, a set of 18 city and county birth-to-five and preschool programs that began meeting in 2022 to help one another expand services quickly and equitably. This brief summarizes the findings and best practices from the working group regarding the role of family outreach in enrollment, and shared experiences of family outreach initiatives in the working group's respective communities is discussed. Even though it is found that children benefit from earlier developmental experiences and families and communities gain from the support that programs provide to working families, some areas struggle to enroll families in programs--especially some of the most marginalized and underserved. Outreach campaigns can play a critical role in program recovery and launching new programs. Other briefs created from the ECE Working Group's findings include "Connecting More Families to Early Care and Education Programs through Streamlined Enrollment," which explores how to make enrollment as seamless as possible once families understand their early childhood opportunities, and "Participatory Planning to Build Stronger Early Childhood Policy and Programs," which advocates for the participation of people in policymaking.
