The guide provides a basic framework for testing risk limiting audits in diverse contexts by outlining foundational prerequisites and operational, legal and regulatory considerations

In this paper, authors explore how ballot length affects specific types of voting errors, including human-machine interaction errors and voter ballot-marking errors.

This paper shows how reporting data at the ballot-card level can reduce risk limiting audits sample sizes and improve audit efficiency.

In this paper, Pettigrew demonstrate that for every additional hour a voter waits in line, their probability of voting in the subsequent election drops by one percentage point. He finds that negative experiences carry over to future elections disproportionately for underrepresented voters.

In this paper, authors find that non-white voters are more likely to lack acceptable photo identification, and that those voting without ID are disproportionately Latino and Black.

This report discusses ballot-accounting audits as a complementary check to tabulation audits, emphasizing reconciliation and chain of custody.

This MS thesis examines how polling place layout and path directionality affect voting system performance across turnout levels. The author models a two-step voting system in a theoretical 1,000 sq ft polling place using discrete event simulation, testing multiple layout configurations and voter routing strategies. They find that perimeter layouts with unidirectional voter flow minimize average travel distance and time-in-system across turnout levels.

This paper examines which voters are disenfranchised by voter ID laws, finding disproportionate impacts on Latino and Black voters who are more likely to lack required identification.

This report provides a national overview of post-election audits, audit types, history, and state practices across the United States.

This toolkit helps election officials design and produce the materials poll workers need to set up and operate a polling place or vote center, including layout diagrams, signage, and procedural materials. It covers both traditional polling places and vote center models.

In this paper, authors test whether voters can detect malicious manipulation of ballot-marking devices, finding low detection rates and showing that signage and poll worker prompts can modestly improve verification rates.

This paper compares in-person versus absentee voting, finding that voters randomly assigned to in-person voting reported significantly higher levels of voter confidence than those assigned to absentee voting.
