I've heard of it at one gym, from transfer gymnasts who insisted they held girls back so they could win. Now I don't know the real motivation, but I do know they often did have girls repeat 3 times. I've met some of them. At my dd's gym, it is very rare that girls repeat compulsory levels. Several even skip the not required levels, or score out of levels and move up quickly. They aren't pushed, their score-out scores are usually 35+. I just couldn't pay those fees for 3 years in one compulsory level for no reason, only if there was a really good reason. Sandbagging is frowned upon, so I'd ask a lot of questions if they want your dd to repeat 3 times, it better be because she doesn't have skills or for age requirements, not "just because that's what we do." Gym is expensive, repeating for no reason is a waste of your money, her time (and your time).
