Arizona Supreme Court to decide if Prop 212 survives signature challenge

The initiative to restrict Arizona's universal ESA program is roughly 10,000 signatures short under a lower court ruling. The high court is weighing whether duplicate signatures were double-counted, which could add back about 24,000 signatures and save the measure.

The Arizona Supreme Court is deciding whether Proposition 212, the Protect Education Act, will appear on the November ballot. The initiative would impose the first major restrictions on Arizona's universal Empowerment Scholarship Account program, now serving over 100,000 students at an annual cost exceeding $1 billion. A trial judge ruled the measure falls about 10,000 signatures short of the 255,949 required, but the high court is weighing whether his formula improperly double-counted invalidated duplicate signatures. If the court agrees, roughly 24,000 signatures would be added back sufficient to qualify. The court is expected to rule by August 20 to meet the ballot printing deadline.

What Prop 212 would do

Proposition 212, formally the Protect Education Act, would impose an income eligibility cap of $150,000 per year for families joining the ESA program starting in 2027. The cap would not apply to students already enrolled before the 2022 universal expansion, including children with disabilities. The initiative would also ban non-educational and luxury purchases, require background checks for school staff with unsupervised student contact, mandate academic testing, and revert unspent ESA dollars to a public school classroom site fund, according to an analysis by the Arizona Legislative Council.

The legal dispute over signatures

The Protect Education Accountability Now committee submitted 415,438 petition signatures by the July deadline. The Secretary of State's Office reduced that to 389,376 signatures eligible for verification. Arizona's 15 county recorders conducted a 5 percent random sample and returned a combined validity rate of 75.2 percent. That rate is applied to the total universe of verifiable signatures to project whether the initiative meets the 255,949 threshold.

Maricopa County Superior Court Judge David McDowell ruled that, based on the validity rate and his formula for handling duplicate signatures, Proposition 212 would fall about 10,000 signatures short. He disqualified 24,369 duplicate signatures and struck thousands more from circulators he found unqualified, according to Tucson.com (Capitol Media Services).

The Arizona Supreme Court is now reviewing whether McDowell's formula improperly double-counted invalid signatures. Prop 212 backers argue that removing duplicate signatures during litigation and then applying a county validity rate that already accounts for duplicates counts some bad signatures twice. If the court agrees, approximately 24,000 signatures would be added back to the pool, giving the initiative just barely enough to qualify. If not, no scenario under the 75.2 percent validity rate keeps Prop 212 on the ballot.

Related ballot language fights

The Arizona Supreme Court separately ruled that the GOP-controlled Legislative Council's description of Prop 212 for the voter information pamphlet was argumentative, speculative, and non-neutral. The description told voters the initiative would give the sponsoring committee the power to sue families and private schools participating in the program. Chief Justice Ann Scott Timmer ordered that language removed and rewritten, according to the Arizona Mirror.

Maricopa County Superior Court Judge Julie Ann Mata also ruled that Secretary of State Adrian Fontes acted illegally in using the word vouchers to describe Empowerment Scholarship Accounts in the ballot description of Prop 212. She cited a 2014 Arizona Supreme Court distinction between vouchers, which were found unconstitutional, and ESA accounts. She ordered Fontes to reword the description.

Competing ballot measure and funding

Republican lawmakers placed a competing ballot measure on the ballot that would nullify Prop 212 if both pass and would make future changes to the ESA program nearly impossible. A Maricopa County Superior Court judge struck that measure from the ballot, but Republicans are appealing. The Arizona Education Association and Save Our Schools Arizona argue it violates the single-subject rule.

The Protect Education Act campaign has spent more than $7.2 million. Approximately $6.5 million came from the National Education Association and about $500,000 from the Arizona Education Association. The ballot printing deadline for the general election is August 20.

Analysis

By the School Decision Newsroom, written after the reporting above was filed.

About 20,000 current ESA families would lose eligibility under the $150,000 cap

Common Sense Institute Arizona estimates that 24 percent of current ESA families have household incomes above $150,000, meaning roughly 20,300 students would be disqualified when the cap takes effect in 2027. The cap adjusts for inflation at only 2 percent per year, while Arizona incomes have grown closer to 4 percent annually. CSI projects that by 2045, more than half of Arizona families with school-aged children would exceed the cap and be excluded from the universal program. A family earning $151,000 loses the full benefit with no phase-out.

Two Supreme Court rulings are due by August 20, not one

The same court faces a second pending decision: whether to restore Proposition 145, the Republican legislature's competing measure that a trial judge struck for violating the single-subject rule. Prop 145 would nullify Prop 212 if both pass and make future ESA restrictions nearly impossible. GOP leaders appealed, and the court has not yet scheduled arguments. If the court revives Prop 145 and both measures reach the ballot, a parent who votes for Prop 212 could see it voided by Prop 145 even if both win a majority.

No state has imposed an income cap on an existing universal ESA program

Arizona would be the first. Wyoming launched the closest analog in 2024, but it started with a cap at 150 percent of federal poverty, about $46,800 for a family of four, less than a third of Arizona's proposed $150,000. The Wyoming program opened applications in January 2025 and is too new to show enrollment or fiscal outcomes. A 50-state survey by the Education Commission of the States identifies 12 universal programs and 27 income-restricted ones. Every income-restricted program was designed that way from the start. Arizona would be the first to retroactively narrow a program families have already built schooling decisions around.
