<p>I think sample lessons are critical. My D has taken several lessons and has sat in on lessons. The decision for sample lessons was based on a lot of research - emailing former students and colleagues and other teachers at the school for recommendations. One teacher studied at Curtis with her private teacher so that was an easy choice. My D knew right away -from either observing or taking a lesson - whether she was interested in the teacher or not. Her teacher also prefers for her to study with a soprano so she has chosen schools where there is more than one soprano who has a good reputation in working with young voices. It is scary to consider, but voices can be ruined. The student has to recognize when things are being done to cause damage and they have to be proactive. My D’s teacher is working with two students now who left very well known conservatories because of technique problems. There is a lot of info out there but you have to dig. Former students are surprisingly honest about the strengths and weaknesses of their teachers. Some of the things I like to know are whether the teacher misses an inordinate number of lessons because of their own performance schedule and whether studio politics is manageable. Of course, the problem is that you are not guaranteed that you can get the teacher you hope for so it is always a bit of a crap shoot. That is why she didn’t apply to schools where there was only one teacher that was acceptable.</p>
