The Ring chooses its wearer. If the ring thinks Kyle Rayner (or Arisia, or whatever teen) is not capable of wielding it, it wouldn't choose them. There are some limitations with rookie rings, but they're removed after basic training - in the Green Lantern Corps. The Corps looks after its own for training, they wouldn't need a Team for it.
