Educational Note: Only 17 of the 18 administrative regions of the Philippines are under the jurisdiction and general supervision of the Department of the Interior and Local Government (DILG). The Bangsamoro Autonomous Region in Muslim Mindanao (BARMM) is the sole exception — it operates under its own organic law and answers directly to the President of the Philippines.. (This distinction is often misunderstood, as many Filipinos assume BARMM is under the DILG — it is not.)
