Providing funding for school materials, supplies, and operating costs.

HB 2147 increases state funding for school materials, supplies, and operating costs in Washington State to address inflation-driven budget shortfalls affecting school districts. It establishes a new funding formula based on prototypical schools (600 high school students, 432 middle school students, 400 elementary students) with specific class size standards (e.g., K-3 at 17 students per teacher) and minimum staffing allocations. The bill requires transparency by mandating the Superintendent of Public Instruction to publish per-pupil funding reports online, which school districts must link to their websites. It also includes targeted provisions for career-technical education, lab science class size reduction, and high-poverty schools with over 50% free/reduced lunch eligibility. The legislation amends existing law (RCW 28A.150.260) to adjust funding allocations based on actual student enrollment and school type.
