Male tappers are gold and often get discounted tuition at studios. Ask around and find out what studios compete and then google those competitions, along with the studio name, to see their placement in tap competitions. If he's going into tap, he should start at the best and those studios will also have the most respect for male tappers. The mother should talk to the director, too, as most of them will work with concerned parents of little boys to make the situation comfortable because they are that valuable. Best wishes to your friend.
