Boulder County’s Election Audit and Canvass Open to the Public

Audit to check election outcomes from the 2024 Presidential Primary Election


Boulder County – The public is invited to observe the Boulder County Election Division’s 2024 Presidential Primary Election risk-limiting audit (RLA) beginning on Tuesday, March 19 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 considered the “gold standard” test 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, March 19 (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 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.
