To be a teacher you need a lot of education. First, you have to complete high school. Next, you have to go to college. It's best if you can get your college degree in the same subject you want to teach. After college, you need to enroll in a teacher certification program. Most teaching certification programs require you to do at least one semester of student teaching. Some teaching certification programs also allow you to earn your master's degree (and then you can earn more money!).
