Vote Count Verification Committee
In Arizona, hand counts are performed to verify the machine counts from a sample of precincts and early ballots from each County. The Vote Count Verification Committee meets, pursuant to A.R.S. §16-602 (K), to establish the designated margins for conducting hand counts.
The Vote Count Verification Committee met on February 28, 2014. At that meeting, the committee voted to keep the designated margins the same as they have been since 2006. The designated margin for polling place ballots remained 1% lower than the designated margin for early ballots as it was noted that more room for error in marking ballots exists for early ballots than for polling place ballots.
The designated margins are as follows:
- Early Ballots – The designated margin for early ballots is set to five votes or two percent, whichever is greater.
- Polling Place – The designated margin for polling place ballots is set to three votes or one percent, whichever is greater.
History of the Committee
In 2006 the Arizona Legislature passed a law (SB 1557) requiring a random sample of voting precincts to be hand counted after the elections.
Pursuant to A.R.S. §16-602, the Secretary of State appointed seven members of the Vote Count Verification Committee, to designate the margins used in reviewing the hand counting of votes and to set the acceptable variance rate between the machine and hand counts.
