Effective for the 2018 AAU Districts and AAU State tournaments, new weight classes will be used in the A (grades 3-4) and B (grades 5-6) divisions. The Iowa AAU wrestling committee has been looking at the size of weight classes in each of the eight AAU District sites over the past three years. In both the A and B divisions a large percentage of the wrestlers are in only a few weight classes. Many brackets in these weight classes had over 20 competitors while other weight classes often have four or less. One weight class has been added to both the A and B division and the weight classes have been changed slightly. Just as the National Federation of High School wrestling has changed the high school weight classifications on several occasions to allow for more opportunities for high school wrestlers, we are hoping these new AAU classifications will create more opportunities for youth wrestlers. Listed below are the old and new weight classifications.
There will be NO change to the C (grades 7-8) division weight classes at this time as there is a good distribution of wrestlers in the weight classes in that division.
