The jurisdiction of the Commission consists of three elements:
Appointing police officers - that includes handling applications and an entrance of eligibility examination and agility tests. Customarily, commissions such as this one will hire testing consultants to compile these examinations.
Promotions - the Commission is empowered or required to administer a second type of competitive examination plus oral interviews for the purpose of ranking fitness for promotion. There are other requirements such as grades, rank and time in that rank.
Discipline - the Chief of Police has the power to impose certain disciplines; on other matters he has the power to impose charges against an officer and that officer can request a hearing before this Commission before the proposed discipline can take effect.
