Thank you for getting this publshed in the By-Laws. FYI it's under: Section III Tournament Operations, Article I #5:
(5) All Folkstyle sanctioned tournaments must comply with the rules in the annual publication by the National Federation of State High School Associations (NFSHSA), unless otherwise specified in this document. The following modifications refer to the NFSHSA rule that has been modified and apply to all sanctioned Folkstyle tournaments. USAWKS requires all sanctioned tournaments to submit a list of officials used to the head official in each district to begin tracking officials. This list must be sent to the Officials Director. All USAWKS sanctioned tournaments will ensure when a female division is offered, females will NOT be allowed to compete against male competitors.
