Treibball
The National Association of Treibball Enthusiasts is the most actively documented US sanctioning body. Its identity is a games-based titling system: instead of one universal Treibball trial, NATE structures competition as a catalog of named games — each with its own rules, level brackets, and qualifying-run requirements. A team earns titles separately in each game. NATE also runs a Skills Certification Program for handlers who want a structured pathway short of full competition, and it accepts video titling for teams without a local club.
