Auditing is the practice of independently reviewing election processes and outcomes. The category covers pre-election logic and accuracy testing of voting equipment, post-election risk-limiting audits, performance audits of election offices, compliance audits against federal and state requirements, and financial audits of election administration spending.
Why this category matters for election security is that audits are how election offices demonstrate that they did what they said they did. A jurisdiction can have the most secure procedures in the world, but without independent verification, the public has only the word of the officials. Audits convert that claim into evidence.
The most visible form of election audit in recent years is the risk-limiting audit (RLA), a statistical procedure that compares reported results against a hand count of a random sample of ballots. RLAs are now required or recommended in a growing number of states. They provide a quantitative check on whether the reported outcome is consistent with the underlying ballots, with a controllable probability of confirming an incorrect result.
The terminology in this category covers both the specific audit procedures and the broader discipline of independent review. The concepts here are procedural. They describe how an audit is designed, conducted, and reported.
Key Concepts
Risk Limiting Audit
A post-election audit that uses statistical sampling to confirm reported results with a specified probability of detecting error.
Logic And Accuracy Testing
Pre-election testing of voting equipment to confirm it correctly records and counts a known set of test ballots.
Post Election Audit
A review of election results and procedures conducted after the election to verify accuracy and identify discrepancies.
Recount
A re-tabulation of ballots, often triggered by a close margin or a formal request, that may be conducted by hand or by machine.
How These Terms Relate
These concepts together describe the discipline of election auditing. The terminology covers the full range of audit types: pre-election testing, post-election statistical audits, recounts, and compliance audits. The unifying theme is independence. An audit is valuable to the extent that the people conducting it are free to find and report problems. The election-specific application of that principle is the work of designing audit procedures that can confirm or refute the correctness of election outcomes within the time available.
