I know at my school at least that several of the piano faculty had students that were in middle and high school, but again they were not teaching ear training or anything, but classical piano performance. They don't even teach theory during lessons, because they expect you to pick that up during theory class time. They are concerned about your piano performance techniques, such as finger placement, correct tone from EACH finger, and correct position of your arm, elbow, etc. It does help you in full understanding of the piano, but gospel had to come on my own time.
