Teacher certification is a formal process that verifies a person's qualifications to teach in a school. It typically requires completing a degree in education, passing specific exams, and fulfilling student teaching requirements. Certification ensures that teachers have the necessary knowledge and skills to effectively educate students. Each state in the United States has its own certification requirements, which may include background checks and ongoing professional development. Once certified, teachers can apply for jobs in public schools, and their certification may also be recognized in other states through reciprocity agreements.
