My thoughts listed above after the category. Then more below.
What about cleaning stalls, feeding, and grooming horses?
Depends on what - just idle saturday hanging out at the barn, pick a stall here or there? I wouldn't. If it's experience that really gets into the husbandry aspects of it - all the sweat and long days that go along with stable upkeep - then I would keep it.
I was in the campus equestrian club for several years and spent hundreds of hours working at the barn -- I wasn't compensated except for getting to ride the horses and take some lessons.
Definitely put this in.
It seems that this could be considered part of normal horse ownership if it were my own barn, but it is also horse-related employment of sorts, albeit without the traditional exchange of money.
That's the issue (or great thing, depending on how you look at it) with the horse world. I'd say anything that you were compensated for in any way (pay, riding, lessons, etc.) would be a good way to break it down. I also think that people who grow up on farms should use that as animal experience.
Here's the way I broke my experience down, and a brief explanation of why I chose to include/not include:
Included:
Working as a stable hand (in the discussion section, I mentioned all the routine stuff such as stall cleaning, feeding, turnin/out as well as something along the lines of 'responsible for administering first aid and treatment for ongoing medical issues', to group all the unusual stuff in the same heading.)(job)
Working Student position (compensated in lessons for work)
Teaching riding lessons/horse care (job)
Pony Club (documentable levels/participation)
Training other horses (again, compensation in some way)
Did Not Include:
Taking lessons (that's more the 'sport' aspect than the horsemanship aspect)
Riding for pleasure (again, more the sport aspect of it)
Any medical treatment for my own horse or horses I was leasing, even ongoing, traumatic ones that took many hours and give lots of experience (this is part of ownership)
Competing (again with the 'sport' aspect)
All the other random things that go along with being a horse person
I think it really does depend for everyone, though. Especially in terms of lessons - if person A is competing at a high level, teaching, etc. in my mind, pointing out the lessons they took is kind of overkill. If person B has been taking lessons, but not much beyond that, they should definitely include them because that puts them above the average person in terms of horse experience...
Not sure exactly how to break it down. Compensation/no compensation? Compared to layperson/compared to other riders, depending on your level of experience? Hmm...
