The Lodge Key 3 consist of the Lodge Chief, Lodge Adviser, and Lodge Staff Adviser. The Lodge Chief is the youth representative elected by the youth members of the lodge. The Lodge Adviser is an adult volunteer appointed by the Council Executive (Supreme Chief of the Fire). The Lodge Staff adviser is a member of the council's professional staff.
Along with the Chief, the Pellissippi Lodge membership elects a Vice Chief of Administration, Vice Chief of Program, a Lodge Secretary, and a Lodge Treasurer. These positions make up the Lodge Officer corps. These officers, along with the elected Chapter Chiefs and appointed Committee Chairmen to constitute the Lodge Executive Committee or LEC, which acts as the steering committee for the lodge.
Within the lodge are five chapters, which align with the council's districts. The chapters of the Pellissippi Lodge are:
- Cades Cove
- Eagle Creek
- Mt Cammerer
- Mt Le Conte
Each chapter has it's own Key 3 of Chapter Staff Adviser, Chapter Adviser, and Chapter Chief. The elected youth of the chapter may include the Chapter Chief, Chapter Vice Chief, and the Chapter Secretary.
Each chapter may also have standing committees similar to the lodge. The chapters meet regularly and take care of much of the regular business of the lodge, such as holding elections, camping promotions, crossover ceremonies, and more.
