I think the term "novice" is widely over used in the equestrian world because you have I think different levels of novice: -
Riding School Terminology: -
Novice/beginner - Anything from the lead rein to someone who has recently gained a lot more confidence riding alone, without even a runner next to them and has attempted a canter.
We then progress through to better beginners at our RS, which you have to be able to W/T/C, prepare your horse yourself (tighten girth, lengthen stirrups etc), do circles, figures of 8 and attempt a small x-pole.
Intermediate - all of above, work without stirrups in all 3-gaits, more advanced lateral work, higher jumps, small course, attempt smaller jumps on x-country.
Advanced - all of above plus harder lateral work, bigger jumps, larger courses be able to ride any of the horses on the yard.
Now personally nothing against anybody who rides at any of those levels but there are very few in the intermediate that I know could ride my old share and she was in many ways a novice pony, in the school very easy to ride although very 1-sided she was willingly and reliable, on hacks as bombproof as they come, never spooked and if did consisted of standing and looking at for maximum a minute, never anything more. But in winter was very strong due to getting little turnout and weekend rides only. So would never put anyone on her that I didn't think could cope.
But then you look at serious high standard competitions and the novice dressage tests and x-country courses are ones I know the "advanced" riders from a RS would struggle with.
To me "Novice" means the following: -
In terms of pleasure/non-competitive riding someone who's confident in all 4-gaits, can happily cope with spooks nothing major but an average spook, in the school and out on the roads and has hacked out in company and alone. Someone who has a basic knowledge of stable management needs of a horse.
I would say that now I am only just getting to "Novice" by terms, although I was considered an Intermediate/advanced rider at my RS. I can ride my new share in 4-gaits, cope with spooks of all degrees, napping, spinning on roads, bolting on bridleways and broncoing in the school without getting too stressed. Will hack happily alone and in company without feeling terrified (hated hacking alone).
