Election Administration Resource Center

Earc provides one of the most important resources available in the election world, rctab. Rctab is a free, open-source tabulation software that uses ballot data from voting systems to run the round-by-round count. Over the years, multiple professional developers have volunteered their services to help us create user-friendly, secure software that breaks down barriers to implementation.* rctab has been approved or certified for use as standalone software in four states: maine, new york, utah, & virginia.* rctab has been approved or certified for use as part of a whole voting system in california (hart verity 2.4) and oregon (clear ballot clearvote 2.5). Clearvote 2.5 is also currently under testing with the u.s. Election assistance commission (eac).* in 2024, rctab was used in 5 elections in jurisdictions representing just over 1.3 million registered voters.* over 1.7 million votes have been tabulated over the life of rctab, with almost 800,000 being tabulated in 2024.* version 2.0 is currently in the final phase of preparation and testing. Rcvrc is working with several voting system vendors regarding rctab integration.
