Part 4: Asia discusses an often overlooked part of testing - having an appropriate mount. She explains that the mount rider choses to test with can be leased or owned, and it must have the training and skills required for the levels. For example, all horses must be able to stand still for bandaging and turn out inspection. The horse must have the appropriate skills for the test, like being able to jump the required height, being willing to jump the required height, or perform the movements. Without this, riders are rarely successful.
