WCA Regulations

Older Versions of the Regulations

Until 2011, the Regulations were maintained by Ron van Bruchem and the WCA Board. Since then, the WCA Regulations Committee is in charge of them.
Previously, from the January 1st, 2013 release until the January 1st, 2025 release, the WCA Regulations were split into the WCA Regulations and the WCA Guidelines. The former contents of both documents were combined into the WCA Regulations for the July 17th, 2025 release.

Here are all past and current versions of the Regulations.
