<p>allmusic, if that was a question, the answer is Yes: At least some of the faculty at Juilliard and Colburn have TA’s teaching performance, with regular but less frequent lessons with the faculty, either in a master-class/studio setting or one-to-one. Can’t speak for the other conservatories, except Oberlin, where that is not the case, though faculty, as in the college, have sabbatical opportunities, usually taking them in semester rather than year increments, at which time, substitute faculty are hired for that period, sometimes young performers at the start of their teaching careers (so about the equivalent of a Juilliard TA). Is this bad? Nobody asks for their money back, but they’ve paid an awful lot, so it is something to consider if part of it goes for lessons with sons and wives of famous teachers - who may be very good, but it sounds a bit nepotistic. Also, consider that TA’s and adjuncts are not paid as well and don’t get the benefits that regular faculty do.</p>
