Substitute Senate Bill (SSB) 5357, laws of 2017, required the Washington State Department of Early Learning, now the Department of Children, Youth, and Families (DCYF), to establish a four-year pilot project to license "outdoor, nature-based early learning and child care programs," otherwise known as "outdoor preschools." As part of this project, DCYF and stakeholders in the outdoor preschool industry formed the Outdoor Preschool Advisory Group (OPAG) in August 2017 and began meeting regularly to maximize the inclusion of stakeholder input and expertise. The pilot project began with 14 different outdoor preschool programs across 22 sites throughout Washington, ready to participate as either an "implementer" or "observer" in a two-tiered pilot project structure. This report covers DCYF's efforts since the last report delivered to the legislature in January 2018 (see ED601972), and details DCYF's plans for the remainder of the pilot project.
