Collected gaits are asked for in dressage tests from the mid-levels upward, at the walk, trot, and canter. Additionally, a high degree of collection is required of the rider in more advanced dressage moves, such as the pirouette, piaffe, and passage. The ultimate level of collection is the levade, in which the horse carries 100% of his weight on his hindquarters. Unlike a rearing horse, the horse's rear legs are well under it, and it can safely support itself in an upright position for a time and then lower itself to the ground under control.
