the term HWT is a term that has been around since dirt. Back in the day, all upper weight divisions were termed HWT. Whether it was Jr High or High School. And yes, years and years ago our kids upper weight division was labeled as HWT.
We have since changed{many,many moons ago} to the actual weight classes as you see now. Every age division has the 3 upper weights as " Heavy Weight " Brackets. Thus as example, in 8& under the first class of Hwt starts at 95# and goes up 15# to 110# then to 125#. Then the 8&under weights stop there. And the top three weights in each age division do the same thing. Only difference is the weight spred per age division. 15# in 8, 20# in 10, 25# in 12, 30# in 14's and 35# in the new high school division.

Hope this clears things up a little. People are just used to lumping the upper kids into the "HWT" division. The top three in each age division are the "HWT" classes. Where people have to be careful is the fact that all of these weight divisions have exact weight limits on them, example: 125# in 8& under. a wrestler may only weigh 125 or below. we cannot create or fudge up and let an 8 & under kid weighing over 125 compete in the 8&under division. During invitationals he may bump up to 10 & under to compete but when qualifying series comes around, he must adhere to the weight limits in his own age divisions. Got this from a district rep. Found this very intresting because I did not know this. Not sure many people do. Most tournaments don't do this.
