Police agencies are usually military like organizations, so that with specified experience or training qualifications officers become eligible for promotion to a higher supervisory rank, such as sergeant. Promotion is not automatic and usually requires the candidate to pass some kind of examination, interview board or other selection procedure. Although promotion normally includes an increase in salary, it also brings with it an increase in responsibility and for most, an increase in administrative paperwork. Unlike military service, it is not unusual for police officers to remain or choose to remain at lower levels, choosing not to apply for promotion. There is no stigma attached to this, as experienced line patrol officers are highly regarded.
Dependent upon each agency, but generally after completing two years of service, officers may also apply for specialist positions, such as detective, police dog handler, mounted police officer, motorcycle officer, water police officer, or firearms officer (in countries where police are not routinely armed).
