Johnson County will test the voting equipment for the June 2, 2026 Primary Election at 10 a.m. on Monday, May 4, 2026, at the Auditor’s Office,913 S. Dubuque St, Suite 130, Iowa City. Testing ensures all voting machines are working accurately and reliably for Election Day.  

Everyone is welcome to watch the testing process, including party representatives, candidates, media, and community members. During testing, pre-marked test ballots with known results are run through the machines to make sure the tabulators count votes correctly.

“Our goal is to maintain voter confidence through transparency and verification,” said Johnson County Auditor Julie Persons. “Public testing is a great opportunity to see firsthand how we verify the integrity of the equipment and the election process.”
