Certification and licensure requirements can vary depending on the grade level you want to teach, so be sure to check with your state's Department of Education for more information. In general, most states require that you complete an accredited teacher preparation program, pass a standardized test (such as the Praxis), and complete a certain number of hours of field experience.
