committees responsible for ceremonies, service projects, publications, unit elections, camp promotions, and dance teams composed of youth members. Lodges are grouped into sections that are then grouped into regions. The section chief is the elected youth leader, a volunteer adult is appointed as the section adviser, and the area director (or his designate) is the professional (staff) adviser. In addition to the section chief, the section has two additional elected officers. The vice chief and secretary are elected immediately following the election of the section chief at the section's annual business meeting. All sections gather annually at a section conclave held in the late spring or early fall. It is the main duty of the section officers to lead the planning of this weekend with the help of the lodge chiefs in the section.

Each region chief is elected at the national planning meeting the day after the election of the national chief and vice chief by a caucus of the section chiefs from the given region. The members of the region committee consist of the region chief, the region chair, all national committee members from the region, and other appointed adult volunteers. Each region annually has a gathering of all section officers and advisers. As a region, they are trained in topics relevant to their jobs. Each region also provides opportunities for Order of the Arrow members to go through a National Leadership Seminar. This weekend course is highly rated and a lasting memory for many members. The national chief and the national vice chief are selected by a caucus of the section chiefs at the outset of the Order of the Arrow's national planning meeting. At the national level, the OA is headed by the National Order of the Arrow committee of which the national chief
