(10 ILCS 5/24B-9)
    Sec. 24B-9. Testing of Precinct Tabulation Optical Scan Technology Equipment and Program; Custody of Programs, Test Materials and Ballots. Prior to the public test, the election authority shall conduct an errorless pre-test of the automatic Precinct Tabulation Optical Scan Technology tabulating equipment and program and marking device to determine that they will correctly detect Voting Defects and count the votes cast for all offices and all measures. On any day not less than 5 days prior to the election day, the election authority shall publicly test the automatic Precinct Tabulation Optical Scan Technology tabulating equipment and program to determine that they will correctly detect Voting Defects and count the votes cast for all offices and on all measures. Public notice of the time and place of the test shall be given at least 48 hours before the test by publishing the notice in one or more newspapers within the election jurisdiction of the election authority, if a newspaper is published in that jurisdiction. If a newspaper is not published in that jurisdiction, notice shall be published in a newspaper of general circulation in that jurisdiction. Timely written notice stating the date, time, and location of the public test shall also be provided to the State Board of Elections. The test shall be open to representatives of the political parties, the press, representatives of the State Board of Elections, and the public. The test shall be conducted by processing a preaudited group of ballots marked to record a predetermined number of valid votes for each candidate and on each measure, and shall include for each office one or more ballots having votes exceeding the number allowed by law to test the ability of the automatic tabulating equipment or marking device to reject the votes. The test shall also include producing an edit listing. In those election jurisdictions where in-precinct counting equipment is used, a public test of both the equipment and program shall be conducted as nearly as possible in the manner prescribed above. The State Board of Elections may select as many election jurisdictions as the Board deems advisable in the interests of the election process of this State, to order a special test of the automatic tabulating equipment and program before any regular election. The Board may order a special test in any election jurisdiction where, during the preceding 12 months, computer programming errors or other errors in the use of electronic voting systems resulted in vote tabulation errors. Not less than 30 days before any election, the State Board of Elections shall provide written notice to those selected jurisdictions of their intent to conduct a test. Within 5 days of receipt of the State Board of Elections' written notice of intent to conduct a test, the selected jurisdictions shall forward to the principal office of the State Board of Elections a copy of all specimen ballots. The State Board of Elections' tests shall be conducted and completed not less than 2 days before the public test and under the supervision of the Board. The vendor, person, or other private entity shall be solely responsible for the production and cost of: all ballots; additional temporary workers; and other equipment or facilities needed and used in the testing of the vendor's, person's, or other private entity's respective equipment and software. After an errorless test, materials used in the public test, including the program, if appropriate, shall be sealed and remain sealed until the test is run again on election day. If any error is detected, the cause of the error shall be determined and corrected, and an errorless public test shall be made before the automatic tabulating equipment is approved. Each election authority shall file a sealed copy of each tested program to be used within its jurisdiction at an election with the State Board of Elections before the election. The Board shall secure the program or programs of each election jurisdiction so filed in its office until the next election of the same type (general primary, general election, consolidated primary, or consolidated election) for which the program or programs were filed. At the expiration of that time, if no election contest or appeal is pending in an election jurisdiction, the Board shall destroy the sealed program or programs. Except where in-precinct counting equipment is used, the test shall be repeated immediately before the start of the official counting of the ballots, in the same manner as set forth above. After the completion of the count, the test shall be re-run using the same program. Immediately after the re-run, all material used in testing the program and the programs shall be sealed and retained under the custody of the election authority for a period of 60 days. At the expiration of that time the election authority shall destroy the voted ballots, together with all unused ballots returned from the precincts. Provided, if any contest of election is pending at the time in which the ballots may be required as evidence and the election authority has notice of the contest, the same shall not be destroyed until after the contest is finally determined. If the use of back-up equipment becomes necessary, the same testing required for the original equipment shall be conducted.
