# Teacher Certification — Definition & Explanation > From the SchoolBrowse Education Glossary. > HTML version: https://schoolbrowse.com/glossary/teacher-certification **In short:** The credential that allows an individual to teach in public schools, typically requiring education, testing, and background checks. **Teacher certification** (also called licensure) is the credential required to teach in public schools. Certification requirements vary by state but typically include a bachelor's degree, completion of a teacher preparation program, passing standardized tests, and background checks. ## Certification Pathways Traditional certification involves completing a teacher education program at a college or university. Alternative certification programs allow career changers or those with subject expertise to teach while completing requirements. Each pathway leads to full certification upon completion. ## Types of Certificates Certificates are typically subject-specific and grade-level specific (elementary, secondary, K-12). Endorsements allow teachers to teach additional subjects. Certificates must be renewed periodically through continuing education. ## Frequently asked questions **Q: Can you teach without certification?** Public schools require certification. Private schools may not. Emergency permits sometimes allow uncertified individuals to teach temporarily while completing requirements. **Q: How long does teacher certification take?** Traditional programs take 4-5 years (bachelor's degree plus student teaching). Alternative programs vary from several months to two years, often while teaching. **Q: Is teacher certification transferable between states?** Partially. States have reciprocity agreements, but requirements vary. Teachers often must complete additional requirements when moving to a new state. --- Source: SchoolBrowse Education Glossary (https://schoolbrowse.com/glossary).
