This report was commissioned by Multnomah County and intends to inform the details of how a new county-wide preschool program, known as Preschool for All, is implemented on the ground. The findings, based on 24 focus groups and interviews, builds on two years of work led by Multnomah County Commissioner Jessica Vega Pederson and a broad coalition of culturally specific organizations, labor partners, and other community-based organizations. Their work developed a ballot measure for the November 2020 election which asked voters to fund the proposed Preschool for All program. The measure passed overwhelmingly. This report outlines findings and recommendations to inform how the policy intent of the preschool program can translate into practice - with thoughtful, intentional design to ensure that the program meets the needs of the diverse children, parents, and preschool providers.
