Teaching certification is a formal credential that educators must obtain to teach in public schools. It typically requires completing a degree in education, passing specific exams, and fulfilling student teaching requirements. Each state in the U.S. has its own certification process, which may include background checks and continuing education. Once certified, teachers can demonstrate their qualifications and commitment to the profession. This certification often leads to better job opportunities and higher salaries. Additionally, it ensures that educators meet the standards set by educational authorities, such as the National Council for Accreditation of Teacher Education (NCATE).
