Logic and Accuracy Test Procedure

Lynda Roberts, Registrar of Voters, Elections

Overview

Background

A public Logic and Accuracy Test of the vote counting program and ballots is conducted 12 days before the election at the Marin County Elections Office, Marin Civic Center, Room 121 in San Rafael, CA.

The Logic and Accuracy test is designed to provide an overview of the election night vote counting process and to verify that the ballot counting program prepared for the election is properly reading and tabulating votes.

The Marin County Grand Jury and the Marin County League of Women Voters are each asked to select two members to participate on the Logic and Accuracy Board. The public may observe the test.

Duties of the Logic and Accuracy/Observer Board Members

Observe the zero votes summary report being printed and check and sign the report.

Select one or two ballot types at random to be tested.

Observe the ballots selected being scanned on the Accuvote Central Count machines and the summary reports being printed.

Check the summary results reports from each ballot type scanned against the sample ballot for that type to make sure that the results on the reports match the expected results of the test. Sign the reports.

Hand count the ballots for one or more contests to verify the results of the machine count. (This step is optional).

Observe another zero votes summary report being printed and check and sign the report.

Observe the election night vote counting process at the Registrar of Voters' office beginning at 8:00 PM until the ballots from all of the precincts are counted.

Expected Results of the Logic and Accuracy Test

The Logic and Accuracy test ballots are marked to show votes for each candidate and measures according to a test pattern in which the number of votes for each candidate matches the candidates' numerical position on the ballot.

Candidate Number of Votes to Expect
Candidate 1 1 vote
Candidate 2 2 votes
Candidate 3 3 votes
Candidate 4 4 votes
Candidate 5 5 votes
Candidate 6 6 votes

And so on until all of the candidates have the number of votes that corresponds to their position on the ballot.

Measures Number of Votes to Expect
YES 1 vote
NO 2 votes

Overvoted Ballot

All contests have one more vote than is allowed. Expect to see no votes in over voted contests counted.

Blank Ballot

No votes cast for candidates or measures. Expect to see no votes counted on blank ballots.

Primary Election

In a primary election, the expected results will be multiplied by the number of ballots with a particular contest.

Explanation of the Tests

In the Logic and Accuracy test, the ballots from randomly selected ballot types are voted according to a pattern and the results are printed in a summary report. The results on the summary report must match the expected results of the test.

The test pattern is as follows:

For each contest on the ballot, the first candidate receives 1 vote, the second candidate receives 2 votes, the third candidate receives 3 votes and so on, including the write-in spaces for each contest on the ballot. All candidates should have a different number of votes.

The YES on a measure receives 1 vote and the NO receives 2 votes.

The test deck for each ballot type includes one blank ballot in which none of the contests are voted, and one over voted ballot in which all of the contests are over voted.

The printed summary report should include over voted and blank ballots in addition to the votes for the candidates and measures.

Selection of the Ballot Types for the L&A Test

The ballot types to be tested will be selected by the Logic and Accuracy Board.

Conduct of the Test

The Computer Operator prints a zero votes summary report before the test ballots are scanned and gives it to the L&A Board to check and sign.

After printing the zero votes report, the Computer Operator scans the test ballots. After the test ballots are scanned, the Operator prints a summary report and gives it to the L&A Board members to check against the Sample Ballot for expected results. Board members check and sign the report.

Checking the Summary Report for Expected Results

One member of the L&A Board reads from the Sample Ballot while the other member checks the report.

  • The number of votes for each candidate must match that candidate's numerical position on the sample ballot. For example, the first candidate in a contest should have 1 vote, the second candidate should have 2 votes, and so on.
  • All measures should show YES with 1 vote and NO with 2 votes.
  • There should be one ballot with no votes (a blank ballot) and one over voted ballot.

L&A members may hand count the ballots to confirm that the results of the test match the hand count.

Completing the Test

After checking the reports from each ballot type selected, the L&A Board Members sign and date the summary report and Certification of Test Results and give it to the Registrar of Voters. The Registrar of Voters then runs another zero report and gives it to the Board Members to check and sign.

Sealing the Test Results

The Registrar of Voters seals the test results and ballots.

If Mistakes are Discovered

If the L&A Board finds mistakes on the test, the Registrar of Voters will investigate the cause of the mistake/s and correct them. After the mistakes are corrected, the Registrar of Voters will conduct another L&A test to confirm that the mistakes have been corrected and the vote count program is working properly.
