Licensure means a restricted practice requiring a license, which gives a "permission to practice." Such licenses are usually issued in order to regulate some activity that is deemed to be dangerous or a threat to the person or the public or which involves a high level of specialized skill. The danger and skill elements inspire governments not to allow a free-for-all, but to regulate the activity, and licensing is a well-established and convenient method of regulation. Licensing includes such things as pilot and driving licenses, licenses to play professional sports, etc. In the case of certain occupations and professions, licensing is often granted through a professional body or a licensing board composed of advanced practitioners who oversee the applications for licenses. This often involves accredited training and examinations, but varies a great deal for different activities and in different countries. Practicing without a license may carry civil or criminal penalties.
