Child Trends staff presented an overview of the contents of the publication Defining and Measuring Access to High Quality Early Care and Education (ECE): A Guidebook for Policymakers. The authors discussed the Guidebook goals which include promoting a common understanding of ECE access and providing tools for how to measure it across different types of early learning settings. These activities were described as an essential undertaking for state and local policymakers responsible for improving access. Additionally, the webinar featured researchers from two states who have applied the access definition: Herman Knopf in South Carolina and Rachel Gretencord in Connecticut. This interactive webinar offered an opportunity to learn about and discuss how stakeholders can use the definition of access and indicators in the Guidebook to help meet the criteria for equal access to ECE in their states. The ECE Access and Choices Workgroup is supported by OPRE and administered by Child Trends. The goal of our workgroup is to provide a responsive learning community of ECE scholars and practitioners. Through quarterly webinars and occasional in-person meetings, workgroup members stay abreast of new research findings and strengthen research-policy-practice connections.
