There is advancement in teaching English, but the trouble is that the market is so flooded with teachers that moving up is very difficult. There is always someone out there willing to do what you do for less.

Usually upward movement in teaching means one of two things, you've gone back to school for a certificate or Master's or proven yourself as management material. Then there is opening a school, but that process involves risk and lots of time to get your business really going.
