A professional license is an official credential that allows individuals to practice certain professions legally. It is typically required for jobs in fields such as medicine, law, engineering, and teaching. To obtain a professional license, candidates usually must complete specific education and training, pass exams, and meet other regulatory requirements set by a governing body. Licensing helps ensure that professionals meet established standards of competence and ethics, protecting the public from unqualified practitioners. Each state or country may have different licensing requirements, and licenses often need to be renewed periodically to maintain professional status.
