Pros
they often have teachers leave with short notice, so when you start you can start with tons of students. I had two full days from the getgo, which is why I took the job in the first place. the other teachers are usually nice and the teaching, for the most part, is easy.
Cons
the rate of pay is measly and even with a full day, depending on where you're commuting from, isn't worth it. there's a high teacher turnover because of the pay and if you're teaching there, you're going to be teaching students that aren't yours often because of teachers quitting, which isn't great for the students. if the job paid what it should, that wouldn't happen. the school also doesn't turn anyone away and will expect you to teach very, VERY young children (like 2 1/2) a private piano lesson, so good luck with that. there's no pay scale based on education either. I have a master's degree in music and met someone else teaching there with a phD and we were paid the same as another teacher who only had a high school diploma.
