Western Dressage is trained and shown in specific levels which build on each other and which reflect the development of the skills and abilities of both the horse and rider. The tests ridden in shows are used as a measure of the correctness of the horse’s (and rider’s) schooling. The collective marks are based on:

• Gaits: the freedom and regularity of the horse’s movement
• Impulsion: the horse’s desire to move forward, elasticity of steps, roundness
• Submission: the horse’s attention and confidence, harmony with rider, lightness of movements, and acceptance of the bit
• Rider’s position and seat: correctness and effect of the aids
