The Maricopa County Elections Department completed mandatory logic and accuracy testing on its offline voting machines ahead of the July 21 Arizona primary election, the department confirmed Monday.
The testing is a required pre-election step for the county, which the Maricopa County elections facts page identifies as the second-largest voting jurisdiction in the United States, representing more than 60 percent of Arizona's registered voters. The county's current tabulation equipment, the Dominion Democracy Suite 5.5B, received both federal Election Assistance Commission and state certification after the county's Board of Supervisors invested in the system in 2019 for its then-2.6 million registered voters. A pilot test that year in Madison School District produced a 100 percent match between hand count and equipment tabulation results.
Why does logic and accuracy testing matter for property and business owners?
For Scottsdale and Paradise Valley residents tracking ballot measures tied to development, infrastructure bonds, or tax assessments, the integrity of tabulation equipment determines whether those results hold up to post-election scrutiny. Maricopa County's 2022 general election saw tabulation machine issues at roughly 20 percent of its 223 polling places, traced to incorrect printer settings that prevented machines from reading ballot timing marks, according to reporting by Rolling Stone. Pre-election testing is the county's primary mechanism for catching those configuration errors before polls open.
The July 21 primary also arrives as Maricopa County adjusts to new state voting procedures. A 2026 state law allows voters to bring sealed early ballots to vote centers for in-person ID verification before election day, a change the county tested in a mock election earlier this year, according to AZFamily. Approximately 80 percent of Arizona voters already use early ballots; county officials have said the new option is not a requirement and that voters may still mail or drop off ballots as before.
The July 21 primary is the next scheduled election date.
