I walk, trot, canter and gallop with a balanced, quiet seat, and I know how to ask leg yield and shoulder-in at walk and trot. My sitting trot needs some work but it's pretty good all round. I walk/trot/canter bareback. I'm not the prettiest rider in the world but I'm fairly effective.
My current horse is a schoolmaster but he's not one of those pushbutton riding school ponies, he is very sensitive and if you don't ask right, he won't respond.
I jump up to 3' confidently (though I haven't in a while due to saddle issues meaning I can only ride in my dressage saddle) and I've jumped a C grade cross country jump (think 2'10" high and about 3'4" wide, and solid, therefore scary), in my dressage saddle, without catching him in the mouth. He rushes if you catch him in the mouth. He is an ex-B grade eventer, not sure of heights for that, and he was bought with the intention of him showing me the ropes in preparation for the next horse, which was either going to be young, talented and already going kindly, or unstarted. I ended up going with unstarted, though I'll probably have her professionally started when the time comes.
I don't cope well with bolting or out of control type behaviour but I have trained a pony, he was a problem bucker and wouldn't go on the left canter lead when we got him (and would NOT jump), and if you tried to force him to left-canter, he would buck - and when we sold him, he was jumping up to 3', picking up both leads without fail, and competing and placing in jumping. He also would do a fairly consistent leg yield/shoulder in at walk and trot. I trained this, and I probably trained it wrong, but he would do it.
Due to my lack of confidence while out (usually at riding club, though general lack of confidence out is a factor too) I consider myself to be only an intermediate level rider. When I'm on top of that lack of confidence while out, I will be at least one level higher, perhaps more.
I have bought a weanling filly with the support of my (very horsey) parents, the logic being that in 3 years' time when she gets started to saddle, I'll have a lot more experience and confidence, and I'll be able to teach her what she needs to know. If I'm not experienced enough to start her myself, I'll have a professional do it for me. I have experience with very very green-broke horses (my old horse had been broken in for 7 weeks when I bought him, and it didn't go all that well, but we managed to turn it around eventually; won't be making the same mistakes with my filly) and I have a good network of extremely experienced people (experts even - one is a riding coach who has trained horses and riders to state winning level from absolute green) who have promised to help if I need it.
I am an intermediate level rider because of my knowledge and confidence, not my seat and ability. I was told by an instructor at riding club that I was a very quiet rider with great hands. My regular coach says I need to trust my horse more, which is hard for me, because I came off (from him) at a gallop about a month ago and fractured my humerus (hairline), got a bad concussion, and couldn't work for a week, or ride for two. My confidence is my main barrier now.
A year ago, I was little more than a beginner, so you'd be amazed how fast you can progress with the right horse!
