It depends where you are from and where you are teaching. Where I am from, a teacher requires at least two degrees; one is a 3 or 4 year Bachelor of Arts or Science degree; the second is a 1 year Bachelor of Education degree (however, new legislation is changing the 1 year BEd program to a 2 year program). You will have to research the requirements of where you’d like to teach in the future and the requirements of where you would like to go to school. Talking to a school guidance counsellor should help. Good luck!
