Anyway, under No Child Left Behind, in order to teach you have to pass a Praxis Test (expect for in MA, they have their own test) and complete a certification program. A Major in Math, without a teaching certification will normally only allow someone to become a long-term substitute (as little as $60 a day to as much as $120 a day depending on state, district, and need). If you have a Major in Math and Education and are certified you can make as little as $20,000 a year to $39,000 a year to start…typically increasing with each year of service.

A Masters in Math will allow you to teach at the Community College level – salaries differing from state to state and need.

PhD. in math will allow you to teach at the University or college level. Again, pay is based on number of classes. Also, most colleges want their professors to be published in educational journals or have written text books.
