SB 2166 Texas Senate · 89th Legislature (2025)

Relating to testing of voting tabulation equipment.

SB 2166 requires standardized testing of voting tabulation equipment used in Texas elections. It mandates three specific tests per election: one conducted jointly with the public logic/accuracy test (at least 48 hours before voting), one immediately before counting begins, and one immediately after counting ends. The bill specifies that election officials (including the general custodian and central counting station staff) must conduct these tests using identical ballot stock and test materials from the public logic/accuracy process. This directly affects election administrators and voting equipment at both polling places and central counting stations, ensuring consistent equipment accuracy before, during, and after ballot counting.

The bill was finalized in its enrolled version with minor formatting cleanup and the addition of a new section requiring testing of electronic pollbook systems.

Scope change
The bill's scope expanded to include electronic pollbook systems and hash validation testing for voting equipment, while retaining the core requirements for testing tabulating equipment at central counting stations and polling places.
