Voting System Reports Collection

Friday, March 11, 2022

As part of EAC's clearinghouse responsibilities under Section 202 of the Help America Vote Act, the commission adopted a policy authorizing staff to post and distribute voting system reports and studies that have been conducted or commissioned by a state or local government.

To be considered for posting on the EAC website, a state or local government must submit the report to the EAC chair or executive director and certify that the report reflects their experience operating voting systems or implementing EAC's voluntary voting systems guidelines. To submit a request or for more information, send an email to [email protected].

EAC posted and/or linked to these reports and studies as part of its clearinghouse function. EAC did not review the information for quality and does not endorse the reports and studies.
