Firefighters are generally promoted from within the department, first to the position of firefighter, first grade. After they demonstrate successful job performance and gain experience, firefighters may be promoted to positions as lieutenants, captains, deputies, battalion chiefs, assistant chiefs, deputy chiefs, and finally fire chief. Firefighters may sometimes work three to five years or more to receive a promotion to lieutenant. Promotions usually depend on the firefighter's position rating, which is determined by seniority, job performance, and scores made on the periodic written examinations.
