The Board has more than 7,600 staff who serve approximately 58,200 elementary and 25,100 secondary school students.

The DDSB has three independent, coterminous boards, serving English-Catholic (Durham Catholic District School Board), French-secular (Conseil scolaire Viamonde), and French-Catholic (Conseil scolaire catholique MonAvenir) students.

The francophone schools that were managed by the Board are now part of Conseil scolaire Viamonde.

They are responsible for setting the strategic direction and policies that guide action, providing public oversight to the functions of the Board, and approving the annual budget.

The current chair of the board is Christine Thatcher, and its vice-chair is Deb Oldfield.

Learning in the program is curated to be more relevant to each student, and material is taught at an accelerated rate.
