Verified Voting maintains and publicly available, searchable database documenting state laws, regulations, and procedures for post-election audits across U.S. jurisdictions.

This paper, recommends voter-verifiable paper ballots and routine audits of paper ballots to verify tabulation and detect compromised systems.

This report describes Colorado's online risk limiting audits tool, risk-limit concepts, and county-facing implementation details after statewide adoption.

Pew commissioned a 2016 survey of almost 3,000 citizens in five Great Lakes states—Illinois, Indiana, Michigan, Minnesota, and Ohio—as they exited MVAs after completing licensing transactions in order to determine the extent to which their experience complied with the Motor Voter law. Their findings touch on whether voters were offered the opportunity to register to vote or update their registration, how voters registered, and the mean transaction time to register.

This paper sets out principles for reliable post-election tabulation audits, including voter-verifiable paper records, transparency, ballot protection, and statistical rigor.

CEIR has surveyed states about voter registration database security every two years since 2018. These surveys have demonstrated widespread best practices in respondent states.

In this paper, authors provide a concise policy-oriented introduction to evidence-based elections and risk limiting audits, including legislative principles and implementation considerations.

This report summarizes the Orange County Registrar of Voters pilot audit of all countywide election contests.

The analysis finds notable discrepancies in how voter registration data are reported by localities into Mississippi’s Statewide Election Management System (SEMS), as well as discrepancies in how such data are reported by the state to the EAC’s Election Administration and Voting Survey (EAVS). This suggests that some localities face more challenges in managing records under a hybrid structure than others, which can disproportionately impact voters on Election Day, depending on where they reside.

This paper explores voting-rule design choices that can reduce audit burden and improve auditability, with implications for post-election verification.

Using administrative and demographic data over six two-year election cycles, the research finds strong evidence that voter lists are largely absent of deceased registrants and that election officials have gotten better at removing deceased registrants over time. The data also suggest that election officials have a much more difficult time removing registration records of those who have moved out of the jurisdiction.

In this paper, authors introduces ClipAudit, a simplified risk-limiting post-election audit method intended to make statistical audits more understandable and implementable.
