WA HB1031

Superintendent of public instruction must appoint an advisory committee to develop indoor temperature standards, including a maximum temperature recommendation, for public school facilities by September 1, 2025

Advisory committee includes representatives from the Department of Health, environmental justice council, state building code council, school maintenance administrators, teachers' association, school directors' association, and a K-12 parent

Committee must submit recommendations, draft legislation, and implementation timeline to the governor and legislature by January 1, 2026, with cost estimates due by July 1, 2026

Adds "excessive heat" as a qualifying unforeseen natural event that allows school districts to receive state basic education funding when unable to meet the 180-day school year requirement

Superintendent gains authority to define "excessive heat" consistent with National Weather Service guidance and may request appropriations for grant programs to help schools with implementation costs
