Open Competition Alliance

The Open Competition Alliance builds the standards, tools, training, and infrastructure that help competitions run fairly, clearly, and credibly. From established traditions to emerging formats and wonderfully unconventional disciplines, OCA supports organizers, officials, and competitors with practical systems designed to make competition easier to understand, easier to manage, and worthy of trust.
