Expanding the learning assistance program.

SB 5120 revises Washington's basic education funding formula to determine how state money is allocated to school districts. It establishes standard school models (e.g., a high school with 600 students) with specific class size requirements (like 17 students per teacher in K-3) to calculate funding, adjusting for actual enrollment and factors like high-poverty schools. School districts must publicly report per-student funding data on their websites, and the state must publish statewide averages for transparency. The bill affects all Washington public school districts by changing how instructional funds are distributed based on these updated formulas.
