The Parliamentarian is a consultant who advises the President, other officers, committees, and members on matters of parliamentary procedure. The Parliamentarian's role during a meeting is purely an advisory and consultative one.

The Parliamentarian assists with many questions that may arise in interpreting bylaws and rules, or in connection with the work of the Executive Committee and of its officers or committees. Duties may include assisting in the planning and steering of business to be introduced to the membership from the Executive Committee or any Branch Committee.

The Chair of the Constitution and Bylaws Committee may serve as Parliamentarian.
