Now being an observer from Melbourne Australia, curiosity is going to kill the cat but I would like to be enlightened on the structure of junior competitive tennis in the US with me primarily concerned with its grassroot structure and not so much with junior elite tennis which I presume would be structured around national point type tournament system which would contribute to a ranking of some form (same as we would have here). I guess what I am talking about more so is more recreational type tennis (still quite competitive but nothing like the elites). Vaguely, of what I have assumed, junior players represent their schools? Here in Australia, the same occurs but not seemingly to the extent to which it seems to in the US with players playing for clubs with school tennis being more an excuse to cut class than anything else. If anyone could elaborate on my request it would be greatly appreciated.
