I just want to address all of the "special treatment" us coaches give the kids who are on a faster track...
Any coach who has been in this sport more than 1 season can relate to being confronted with "if my child got as much attention as that child, they would be that good too." The problem is, it's just not true. At most gyms, we have a limited amount of full-time/career coaches with decades of experience. Sure if every child on every path got "those coaches," they would likely do better than they would being coached by an apprentice coach (who is in almost all cases being mentored and supervised by the experienced coaches). I will concede that more experienced coaching equals a better gymnast, however, it's not true that they would catch up to the kids who are on a faster moving track. The reason faster moving kids are scouted out and placed with the more experienced coaches and faster moving kids is those kids might lose an opportunity that is well within their grasp (JO champion, college scholarship or elite qualification) if they are placed with a less experienced coach or with kids who slow down their progress. The average gymnast does not lose that opportunity, because they never had the potential in the first place. So when an average gymnast is placed with an apprentice coach, the outcome is that they may only make it as far as level B, when they might have made it to level C if they had the super star coach. They still wouldn't have made it to level E or F. Or they might have still only made it to level B, but they might have scored higher/placed better. The placement did not take away their chances to get a spot on the national team/scholarship, because that was never within their abilities in the first place. With either coach, that gymnast had the fantastic opportunity to be on a gymnastics team which gave them so many invaluable life skills, character traits, friendships and memories (things that go far beyond a level or a score).
There are times when a gymnast does not initially appear to be on the fast track and then out of nowhere they mature or just start working harder and prove themselves to be a late-blooming super-gymnast. That kid should then moved in with the fast moving group. There are also times when a fast-moving kid slows down. They are then moved into a slower-moving group. There are also times when, talent aside, the right chemistry is missing between the coach and the gymnast (or the gym culture) and they need a different environment to bring out their potential. None of those scenarios are the same as special treatment or poor treatment.
