Fair enough.
USDF shows are rated shows. The Intro tests are USDF tests and not USEF tests, meaning there’s no USEF points or awards for them. But they’re still a USDF class. Just like FEI starts at Prix St George, but we have USEF Training, First, Second, Third, and Fourth Levels before that. Each governing body picks a starting point for their shows/organization.
Showing is competing in a specific discipline, not just competing on the back of a horse. You’re not going to put a reiner and a jumper and a pleasure horse in one ring and judge them all together. So, I think it makes perfect sense to not have a beginner rider dressage test. A beginner rider is learning hte basics of riding in general, not a specific discipline. And while I agree that dressage is the ideal foundation for all disciplines, there’s a big difference between learning the basics as fundamentals and actually performing a test to be judged.
I also think the poles classes at h/j shows are silly, and a lot of those kids in them are not ready for show atmospheres, they just happen to have saintly ponies. But someone pushed those through sometime over the years, so maybe there’s enough people that agree with you and you all can petition USDF to make a beginner test.
Or, since you said you don’t find a problem with the requirements of the test, just the judging criteria, find a judge that will judge using criteria you give them. It’d likely have to be yourself, or maybe a kid’s parent that also rides. Or another local trainer you’re friendly with.
