What is the correct progression for developing a hunter jumper horse?

The correct progression for developing a hunter jumper horse follows a logical sequence that builds each skill on a confirmed foundation — beginning with flatwork quality and moving to jumping only after the canter is established, progressing from small fences to larger ones only after confidence and technique are confirmed at each height, and introducing competitive pressure only after the horse can produce quality work consistently in familiar training environments. The flatwork foundation is established first because it determines the ceiling of everything that follows: a horse with a quality, adjustable canter that responds to the half-halt, maintains rhythm without constant driving, and turns smoothly through corners will produce far better jumping than one with a poor canter regardless of how much jumping training is layered on top. Ground pole and cavaletti work develops the horse's coordination and rhythm before any actual jumping demands are introduced, building the proprioceptive awareness of footfall that jumping requires. Small cross rails and single fences build confidence and basic technique at heights where the horse's scope allows genuine relaxation rather than maximum effort. Gymnastic exercises develop specific technical qualities — front end tuck, back use, adjustability — that single fence work does not isolate as effectively. Short sequences and eventually full courses introduce the navigational and pace management demands of course riding after single fence confidence is confirmed. The height increases progressively as technique, confidence, and the horse's physical development support the next step, with each increase requiring confirmation at the new height before further increases. Introducing competition adds environmental and psychological demands that schooling does not replicate, and a horse that performs consistently at home is not necessarily ready for its first show without the additional exposure to the show environment that schooling shows and unfamiliar venues provide before recognized competition begins.
