Hamilton-Wentworth District School Board (HWDSB, known as English-language Public District School Board No. 21 prior to 1999) is the public school board in the city of Hamilton, Ontario, which was formed January 1, 1997 via the amalgamation of the Hamilton and Wentworth County school boards. HWDSB teaches approximately 50,000 students in its 114 neighbourhood schools. In addition to the programming offered at 96 elementary and 18 secondary schools, a number of alternative programs focusing on sports, academics, science, arts and languages are available. The current Director of Education is John Malloy.
The HWDSB has 15 wards and 11 trustees, who are each elected for a four-year term. The Chair of the Board, the Vice-Chair and the Honorary Treasurer are elected at the Inaugural meeting of the Board, and serve for one year. Trustees are officials, elected to serve parents, students, taxpayers and the school system. They are the link between communities and the school board, ensuring Hamilton public schools meet the diverse needs of students in their communities.
