We have one gym in the area that is notorious for having girls spend 2-3 years on the same level. They usually take many top places in the competitions at the lower levels, which makes their gym look good and makes some of the parents happy because there is a lot of hardware around the necks after every meet, but they do lose gymnasts too because they wont progress them.
Ekat, you may be right, and that would be my first thought as well. Mainly because the op isn't talking about her dd learning skills that are good preps for optional work.
It's possible the gym is a good progressive gym that prefers, as I do, to skip as much compulsory work as possible, and have them compete just enough to give the kids an experience base for future levels. The time carved away from the compulsory system can then be used to train progressions and skills that are fundamental to optional development.
I think the best thing to do is watch a couple of practices from beginning to end to see if the kids are training toward punch fronts and roundoff back handsprings, or tumbling into back tucks on floor. Watch each event for skillwork that goes beyond new level 4 and 5. Look for the kids who do optional work. Do they look. at least your untrained eye, as if they'redoing substantial skills on each event? If you don't see it, it's possible it won't be there next year either.
Why????
I knew a coach who's team was very lopsided with compulsory kids, as the coach preferred to move kids into a team track as early as possible. That may sound good, and it would be if the majority of kids wanted to be on a gym team from level 2 to level 5 for a span of 4-6 years, and then begin training optional work in earnest. Sadly, there just isn't enough meat on the bone to keep a kid excited about the sport while working almost exclusively on compulsory routines and skills.
It made financial sense, but not necessarily gymnastics sense. My feeling is it was a choice made to help with the bottom line, because you can collect more money from a three or four day a week kid than you can a one day a week recreational gymnast. To the coach's credit, the kids on team are pretty happy and excited, but I sincerely wonder how they feel when arriving at level 7 or 8 with no time left to realize a mere semblance of their original dreams.
So yeah, really look it over and believe what you see, because the proof really is in the number and quality of their optional kids.
