Which of the following is NOT included in a pattern designed to effectively and appropriately test the exhibitors?

The correct answer is that the walk over poles is not typically included in a pattern designed to effectively and appropriately test exhibitors in certain equine disciplines.

Testing patterns for exhibitors often emphasize skills that demonstrate the horse's responsiveness, agility, and ability to maneuver under different gaits and conditions. Walking over poles tends to be more of a basic skill exercise aimed at establishing comfort and coordination for the horse rather than testing advanced maneuvering or precision under pressure. It is generally perceived as a foundational activity that does not challenge an exhibitor in the same way that jogging over poles, cantering leads, and backing up would.

Jogging over poles assesses the horse's ability to maintain a steady pace and rhythm while negotiating obstacles, while canter leads evaluate the horse’s ability to pick up the correct lead and demonstrate balance and control at speed. Backing up tests not only the responsiveness of the horse but also the exhibitor's ability to maintain control and accuracy in reverse. Each of these activities requires a higher level of skill and coordination, making them more relevant for evaluating exhibitor performance in a competitive context.
