Judging from the high schoolers and recent graduates I've seen in the states, the training seems to focus as much on speed and stamina as much as anything. Not that speed and stamina are bad, but the few people I've been able to watch and practice with, while blindingly fast and able to practice all day and most of the next one, were, for the most part, sloppy and very "bouncy." Lots of head bobbing, ducking, etc, as well as just bouncing up and down. For the most part, if you just stay on center, they impale themselves on your kisaki.

Now, the university students I've met are something else. They still have all that speed and stamina, but add good seme, control of the center, strong posture, etc.
