You have never been on a horse before or have ridden only a couple of times and have never received any instruction. The last time on horseback was so long ago you can hardly remember.
You have been on a horse a few times over the years and felt comfortable but have never taken any lessons or had coaching. You may have trotted or even cantered before without falling off.
You have at some point in your life spent more time with horses but are now rusty or have just recently started taking lessons. You are generally comfortable but would NOT feel safe riding a young or spirited horse. You know how to post a trot and generally don’t hang on to the saddle horn while cantering.
You ride or have ridden regularly (at least once a week) and received riding lessons at some point. The last time on a horse was less than a year ago. You can post (rise) a trot and have an independent seat (do not hold on to the saddle) while cantering. You know the aids to walk, trot and canter departure and know how to ask your horse to sidestep. You can ride a young or spirited horse under supervision.
