How to Become a Police Officer or Detective
Police and detectives must use good judgment and have strong communication skills when gathering facts about a crime.
Education requirements range from a high school diploma to a college degree. Most police and detectives must graduate from their agency’s training academy before completing a period of on-the-job training. Candidates must be U.S. citizens, usually at least 21 years old, and able to meet rigorous physical and personal qualification standards. A felony conviction or drug use may disqualify a candidate.
Police and detective applicants must have at least a high school diploma or equivalent, although many federal agencies and some police departments require some college coursework or a college degree. Many community colleges, 4-year colleges, and universities offer programs in law enforcement and criminal justice. Knowledge of a foreign language is an asset in many federal agencies and geographical regions.
Fish and game wardens typically need a bachelor’s degree; desirable fields of study include wildlife science, biology, or natural resources management.
Federal agencies such as the Federal Bureau of Investigation also typically require prospective detectives and investigators to have a bachelor's degree.
Many applicants for entry-level police jobs have taken some college classes, and a significant number are college graduates.
Candidates for appointment usually attend a training academy before becoming an officer. Training includes classroom instruction in state and local laws and constitutional law, civil rights, and police ethics. Recruits also receive training and supervised experience in areas such as patrol, traffic control, firearm use, self-defense, first aid, and emergency response.
Federal law enforcement agents undergo extensive training, usually at the U.S. Marine Corps base in Quantico, Virginia, or at a Federal Law Enforcement Training Center.
Work Experience in a Related Occupation
Detectives normally begin their careers as police officers before being promoted to detective.
FBI special agent applicants typically must have at least 3 years of professional work experience in areas ranging from computer science to accounting.
Some police departments have cadet programs for people interested in a career in law enforcement who do not yet meet age requirements for becoming an officer. These cadets do clerical work and attend classes until they reach the minimum age requirement and can apply for a position with the regular force. Military or police experience may be considered beneficial for potential cadets.
Cadet candidates must be U.S. citizens, usually be at least 21 years old, have a driver’s license, and meet specific physical qualifications. Applicants may have to pass physical exams of vision, hearing, strength, and agility, as well as written exams. Previous work or military experience is often seen as a plus. Candidates typically go through a series of interviews and may be asked to take lie detector and drug tests. A felony conviction may disqualify a candidate.
Police officers usually become eligible for promotion after a probationary period. Promotions to corporal, sergeant, lieutenant, and captain usually are made according to scores on a written examination and on-the-job performance. In large departments, promotion may enable an officer to become a detective or to specialize in one type of police work, such as working with juveniles.
