Abstract is: A police academy, also known as a law enforcement training center, police college, or police university, is a training school for police cadets, designed to prepare them for the law enforcement agency they will be joining upon graduation, or otherwise certify an individual to become a law enforcement officer, typically a police officer. Police academies train cadets on skills and tactics required to properly and effectively conduct their duties, such as legal training, driving skills, vehicle training, equipment training, firearm training, use of force, crisis negotiation, and de-escalation, among others. Typical facilities in a police academy include classrooms, vehicle courses, shooting ranges, running tracks, gyms, and recreational facilities, though some may also include dormitories, cafeterias, training simulators, police museums, and police-affiliated businesses such as restaurants and stores. Police training varies in important ways around the world, with significant differences in the program content, format, and instructional methods. Police academies are not used solely by police cadets, and may also be used regularly by sworn officers, other law enforcement agencies, special units such as SWAT, and occasionally even civilians and other non-law enforcement personnel; for example, the 1932 Summer Olympics used the Los Angeles Police Academy's range for the shooting event. The requirements to join a police department and attend a police academy vary by jurisdiction, but typically involve background checks, physical, psychological, and medical checks, and criminal record checks.
