Boulder County’s 2025 Coordinated Election Audit and Canvass Open to Public
Audit to check election outcomes from the 2025 Coordinated Election

Boulder County, CO – The public is invited to observe the Boulder County Election Division’s 2025 Coordinated Election risk-limiting audit (RLA) beginning on Tuesday, November 18 along with other post-election certification activities*, as detailed below.

While Boulder County and all Colorado counties have conducted post-election audits since 2005, a risk-limiting audit is the most highly regarded way to test the accuracy of election results. Colorado has been conducting risk-limiting audits since 2017 and was the first state in the nation to conduct a statewide version.

What: Boulder County Risk-Limiting Audit

When: Starting Tuesday, November 18 (see detailed schedule below)

Where: 1750 33rd Street in Boulder; Please RSVP by Monday evening to Vote@BoulderCounty.gov as space is limited; Check in at the Ballot Processing Center

The risk-limiting audit is a test that helps ensure the accuracy of election results and provides the public with evidence that election outcomes reflect the votes cast by voters on their ballots. To ensure tabulation was accurate, the process reviews how a ballot’s votes were captured at the time it was processed by comparing a sample of paper ballots with digital tallies. To learn more about risk-limiting audits, see the Secretary of State’s Audit Center and FAQs on the RLA.

The software that facilitates the risk-limiting audit at the state level is open source, meaning anyone can examine the code themselves and other states are welcome to learn from or build upon it.
