Whether mounting or dismounting from the ground or a mounting block, the horse should stand still until given a command to move.

The horse should stand quietly while being mounted, and for several minutes after the rider is in the saddle. He should also stand quietly while the rider is dismounting, and for several minutes after the rider has reached the ground.

Though it can take time and patience to successfully teach a horse to stand quietly while the rider is mounting and dismounting, it's extremely important. The rider should never be in a hurry to immediately move-off after getting into the saddle, and should not be in a hurry to lead the horse off after dismounting. Although there are times a rider does need to rush, he can always take a second or two to wait before he gives the command to move-off. This way, the horse will learn to wait for the command -- even in a rushed situation -- and not anticipate and move-off without permission.

When a rider is not rushed, he should be in the habit of waiting for a minute or two before commanding the horse to move. If the rider is not constantly in a rush, then the horse won't be either, and the horse will be calmer and more obedient.
