Next Steps for the Colorado Risk-Limiting Audit (CORLA) Program

Abstract: Colorado conducted risk-limiting tabulation audits (RLAs) across the state in 2017, including both ballot-level comparison audits and ballot-polling audits. Those audits only covered contests restricted to a single county; methods to efficiently audit contests that cross county boundaries and combine ballot polling and ballot-level comparisons have not been available.

Colorado’s current audit software (RLATool) needs to be improved to audit these contests that cross county lines and to audit small contests efficiently.
