Halter classes are where a horse is shown in hand.
These classes are usually broken up into Open, Amateur and sometimes Junior. In a Halter class a horse is judged on conformation, manners and movement, with the emphasis being on conformation. In the past the handler and horse would burst into the ring at a trot, however, new rules now have the horses come in at a walk and trot after clearing the gate. You trot around and line up on the far wall to await your turn to go in front of the judge. This means to set him up in a position that best shows off his conformation.
