Following graduation from the Police Constable School, cadets assume the rank of constable and are appointed to a division or department of the Hellenic Police Force on a point-based system. They can be appointed to the rank of police sergeant following at least three years of service and with the successful completion of a promotions exam. If promoted, they join the category of non-commissioned officers.
Likewise, following five years service, police sergeants can achieve promotion to the rank of police inspector through an assessment test.
Graduates of this school serve as investigators; police sergeants and police inspectors normally serve as a duty officer.
Police inspectors can be promoted to the rank of lieutenant by attending the Police Inspector Re-training Department at the Police Academy, a prerequisite for promotion to the rank of police captain (1st class).
Graduates of the Officers School hold the rank of police lieutenant (2nd class) and are officers of the Hellenic Police Force. They can be promoted up to the rank of lieutenant general.
Special duty officers retain a separate ranking system, and can be promoted up to the rank of major general.
Officers are promoted following approval by competent committees, and based on their qualifications and record.
