A ballot measure known as Arizona Proposition 320 seeks to require large school districts in the state to allocate at least 60% of their budgets to classroom instruction. The proposal is set to appear on the 2026 Arizona election ballot and is aimed at directing a larger share of district funds toward teaching.

The measure targets funding formulas for larger districts, specifying the minimum percentage of budget that must support classroom activities. Its purpose is to ensure that a greater portion of district finances is used for direct instructional purposes.
