The young horse tests are not usually ridden by riders new to dressage, because they are a little more exacting than the regular tests.
They are judged by at least two people, which is always fun because there is additional feedback. At bigger shows, there might be three. At CDIs, there are five.
But the feedback is given audibly. At a good-sized show, it’s done over a microphone and at a smaller show, just shouted across the arena. Everyone can hear the comments, and that takes some getting used to.
There is more scrutiny on the gaits and less on exercises in these tests, and, the comments generally refer to the gaits. They will score the walk, the trot, the canter. And if the consensus is that one of those gaits is inadequate, you will hear about it and so will the audience. The idea is to encourage the rider to adjust the training to improve each gait as the horse continues up the levels. It’s more of a riding/training lesson on the spot, with a specific goal, as compared to the normal feedback in your regular test score and its accompanying sheet.
The classes are open to all horses that qualify by age, though, so if you feel you understand what you’re getting into and what is expected, then you are welcome to go for it. Pros and Ammies compete together in them, there’s no separation that way.
