A "prefect" is a student leader in schools, particularly in the United Kingdom and some Commonwealth countries. Prefects are usually appointed from the senior year and are responsible for maintaining discipline, assisting teachers, and serving as role models for younger students. They often help organize school events and promote a positive school environment. In some contexts, such as in ancient Rome, a prefect was an official with various administrative duties. The term can also refer to a high-ranking officer in certain organizations or governments, responsible for overseeing specific areas or functions, such as a police prefect or a prefect of a province.
