Modifying school district allocations for utilities and insurance operating costs.

This bill revises Washington state's formula for allocating basic education funding to school districts. It establishes "prototypical schools" with specific student counts (400 elementary, 432 middle, 600 high school) to determine funding levels, setting class size targets (e.g., 17 students per teacher in K-3) and required staff ratios (like principals, nurses, and counselors per school). School districts must report per-pupil funding transparently on their websites, and the bill adds requirements for funding adjustments based on high-poverty schools and advanced courses. The changes affect all public school districts by altering how state funds cover instructional and operational costs, not direct utility or insurance expenses as the title suggests.
