A method for auditing ballots cast in an election, wherein each ballot is associated with a group. A subset of groups from which sample ballots will be chosen is identified. An identifier is printed on each ballot in the subset. Each ballot has a different identifier than every other ballot in its group. A check is performed to determine whether the identifiers were printed correctly on the ballots. If so, a machine re-count of ballots in each group in the subset is performed and the results are compared to the initial tally of ballots associated with the group. If there is a mismatch, a further investigation is triggered. If there is a match, manual verification is performed on sample ballots from each group. The audit may begin prior to completion of voting from all precincts by estimating the number of samples that will be necessary.
