These best practices came from researching accessibility in RCV, which has historically been ignored in the RCV space. These ballot design best practices are based on research with the Ranked Choice Voting Resource Center about accessible RCV systems.
Our goal was to create a universal design for a Ranked Choice Voting ballot that would work for the most voters without special settings needed. We designed to the interaction modes identified in the Voluntary Voting System Guidelines 2.0 requirements.
These guidelines explain how a successful accessible RCV ballot works for voters with disabilities. Many of them are being adopted for new accessible RCV systems.
