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

SB 5918 increases state funding for school materials, supplies, and operating costs to address inflation-driven budget shortfalls affecting Washington school districts. It amends funding formulas to base allocations on standardized "prototypical" school models (e.g., 400 elementary students, 600 high school students) with specific class size targets, adjusting for actual student counts and school size. The bill requires school districts to link to publicly posted per-pupil funding reports on their websites and mandates transparency in how state funds are distributed across programs like special education. This directly affects all Washington public school districts by changing how they receive and report state education funding.
