The agency is tasked with protecting citizens, property and public order and as of 2015, there were around 40,500 employees.

Members were recruited from the former communist SNB (National Security Corps), after passing a vetting "democratic" commission established after the Velvet Revolution in 1989 to eliminate from the police force communist ideologues and agents of the secret police.

The Police of the Czech Republic has general jurisdiction in the investigation of misdemeanors and crimes.

Its proceedings are overseen by an independent prosecutor, who can bring charges in criminal matters.

Some crimes (such as terrorism) are being solved in co-operation with intelligence agencies such as BIS or ÚZSI.

Regardless of being assigned to nationwide or regional units all police officers while on or off-duty have the right (and obligation) to act if the crime or serious offense is happening and life, health or property may be in imminent danger.

If a police officer still wants to carry a weapon off-duty, he/she has to use their personal handgun like any other armed citizen.

The psychological examination is focused on determining personal prerequisites for the performance of the service.
