The purpose of this test was to verify that voting equipment will operate reliably in conditions approximating normal use by voters. Testing Responsibilities All testing was conducted under the guidance of personnel verified by California Secretary of State (CASOS) to be qualified to perform the testing. Responsibility Assignments CASOS utilized third party testers during the performance of portions of the examination. All testing was executed by SLI Compliance personnel. Schedule Testing was conducted January 7–12, 2026. Examination Procedure Volume testing encompasses the examination and testing of software, and operational tests to validate system performance and functioning under normal conditions. Test entry data, representing voter ballot voting events, tested the system. Scope of the Interactive Sample Ballot system The Interactive Sample Ballot (ISB) system is a web-based application that allows voters to mark selections on a sample ballot, either on their computer or mobile device, prior to formally voting at a Vote Center. The ISB generates a Quick Response (QR) code called a Poll Pass containing voter selections, which pre- populates selections in the Ballot Marking Device (BMD). The ISB also supports Remote Accessible Vote By Mail (RAVBM) and the Uniformed and Overseas Citizens Absentee Voting Act (UOCAVA) voters.
