I personally feel that the US system of developing elite gymnasts is quite superior to,ourmsystem in Australia, and if we were to implement something similar here, we would need a lot more coach education availability to make it work, but it would help us to be more successful at the international level.
Our system selects gymnastsbaround 7 years of age (or younger) and has them train and compete in a totally seperate stream to other gymnasts). Usually training in seperate High Performance Centres. If a gymnasts isn't cutting it in the international,system they can quite easily drop back to the national system, but switching from the national system to the international is not so easy and becomes more difficult with every passing year the child ages.
In our system many capable kids will never have a chance to do elite if they - Start gymnastics later, start to excel later, don't live near a high performance centre, have parents who don't want them training 25 hours a week at 7 years old even though they may accept these types of training hours as their child gets older etc. Most kids train international after being accepted from their gyms to train at the high performance centre. Understandably many clubs don't want to recommend their ymnasts for international levels because they will lose them. These are often the best kids in their gym and once they go to HPC the gyms lose the income they received rom those kids, they lose them from their teams etc.
High Performance Centres are sparse around the country and each con only offer a few limited spots. Families that want their child to pursue elite must often move or send their child away to live with someone else. I know this happens a lot in the US as well, but for us it has to happen at 7 or 8 years old age.
Competition is also a problem. These kids need to be able to represent our country yet they have so few opportunities to compete. There are only a handful of international girls in each state so there are very few competition opportunities. Kids might get to do 2 comps a year in our state, where national level kids could to 10-12 if they wished. Somthese kids get very little competition experience. Because so few kids compete at this level they are often competing to a very small audience, so they don't learn how to compete confidently in front of large audiences. They also have very little competition and end up competing against the same few girls for their entire carreers, while the national levels kids have so any girls to push themselves against.
