STREAMin³ is a comprehensive birth-to-five curriculum model with embedded professional development and a key focus on Core Skills, STREAM skills, and integrated, intentional interactions. In Spring 2022, the Virginia Department of Education (VDOE) selected STREAMin³ to become an open-access, low-to-no-cost early childhood curriculum option in Virginia. This brief summarizes the activities and progress of the CASTL STREAMin³ team during the 2022-2023 school year to provide the STREAMin³ curriculum model to publicly funded early childhood education programs who elected to adopt the curriculum model.
