• The NTUSU Council is the legislative branch of the Union which drafts policies and ensures the policies proposed and executed by the Executive Committee are consistent with the objectives of the Union.
• The Executive Committee is the executive branch of the Union that plans and executes the policies.

The Union consists of 16 academic constituent clubs and 3 non-academic constituent clubs.
