The Ottawa-Carleton District School Board (OCDSB, known as English-language Public District School Board No. 25 prior to 1999) refers to both the institution responsible for the operation of all English public schools in the city of Ottawa, Ontario and its governing body. Like most school boards, the OCDSB is administered by a group of elected trustees and one director selected and appointed by the Board itself. Additionally, annually, two student trustees are selected per provincial regulation.
