Arizona Proposition 320 would require districts with at least 7,500 students, or districts operating a school in a county with at least 500,000 residents, to devote at least 60% of operational spending to direct instructional expenses. The Auditor General would define the relevant spending categories. Districts below the threshold would have to increase their instructional share by at least half a percentage point per year beginning in fiscal 2027–28 until compliant. Continued noncompliance could reduce Classroom Site Fund allocations in 25% increments, subject to limited waivers. The debate is whether a statewide spending ratio improves classroom priorities or oversimplifies legitimate district costs. Families want school dollars reaching students, but percentages can hide real differences among districts. A large district with transportation, security, special programs, or aging buildings may have costs that do not fit neatly under “instruction” even when they support learning.
