The council level organization is similar to that of the National Council. Councils are headed by a collective of three people known as the 'Key 3'. The Key 3 consists of the Scout executive, a paid employee who administers a staff of professional Scouters; a council president, a volunteer, serves as the chairman of a volunteer board of directors; and a council commissioner, also a volunteer, coordinates the efforts of trained volunteers who provide direct service to the units (Cub Scout packs, Scouts BSA troops, etc.).
