Dear WCA Community,

The WCA Regulations Committee would like to inform you that the WCA Guidelines have now been merged into the WCA Regulations, bringing these important documents together. This change improves the accessibility of this information without changing the requirements in place at WCA Competitions.

A new version of the WCA Regulations, incorporating the content previously contained in the WCA Guidelines, has been published. This version is in effect for competitions beginning on, or after, July 17th, 2025.

You can review the changes made in this comparison on GitHub. You can click on “Files changed” to see the complete files of the Regulations and the former Guidelines, where all changes and additions are marked green and removals are marked red.

Changes include:

• Moving all former Guidelines into the Regulations
• Removing the Guidelines
• Updating cross-references to former Guidelines
• Amending the ‘Notes’ header section to reflect the amended structure

The changes made are only structural, and no substantive changes to the procedures in place at WCA Competitions have been made at this time. The WCA Regulations Committee continues to work on the development of the WCA Regulations, and intends to publish the next update to the WCA Regulations to take effect for competitions beginning on, or after, January 1st, 2026.
