LOGIC & ACCURACY TESTING (L&A TESTING)         

Before every election, county boards complete L&A testing to ensure proper coding of ballots and tabulation of votes for every contest.

The purpose of Logic and Accuracy Testing (L&A) is to prove the programming of the ballot, and to test each precinct, machine type, each ballot style, and each contest on the ballot. 

In an L&A test, ballots of each style are coded for a mock election and run through the tabulator. The tests check the voting system’s ability to read each ballot style and the accuracy of the tabulator when counting votes.
