Beyond the degree, most states require you to pass a state-specific teacher licensing exam (often Praxis tests) and complete a period of student teaching or a similar internship. The specific requirements vary significantly by state, so researching your target state's Department of Education website is essential. Some states might also require background checks and fingerprinting.
In short, the education needed is more than just a bachelor's degree; it involves specific coursework in education, successful completion of exams, and practical experience in a classroom setting.
