What are some good training for one on one volleyball player and coach?

Question

especially preparing for his or her first high school game

Answer 1

To prepare for his/her first school game, you really want the team to work together... as a coach or as a parent.

One on one is a good idea for private lesson, but won't get anyone extra playing minutes if the player cannot gel with other players on the team.

Answer 2

probably peppering, as in bump set hit back and forth to just eachother.  if you are a hitter, you might want to work on transitioning and approach and stuff like that.  for every position, there are other things you need to work on to become a great volleyball player :D
