The bill establishes new provisions in chapter 28A.150 RCW aimed at supporting public schools in exploring and implementing later starting times. It mandates the office of the superintendent of public instruction to provide information and technical assistance to school districts considering changes to their starting times. This assistance may include summaries of studies on the health benefits of later start times and insights from districts that have successfully made the transition, addressing concerns such as parent engagement and transportation logistics.

Additionally, the bill creates a later school starting times grant program, which will be administered by the office of the superintendent of public instruction starting in the 2026-27 school year. Grants will be available to eligible school districts for both exploration and implementation of later start times, with the possibility of receiving further funding for implementation after initial exploratory grants. An annual report will be required from the office beginning in 2028, detailing the program's actions and providing insights from other states, along with recommendations for legislative changes to further support these initiatives.
