Police officers are highly trained public servants, and the role has several requirements, including:


Police officers and detectives are typically only required to have a high school diploma or General Education Diploma (GED). Some police departments may require an associate or bachelor’s degree. Any field of study that offers experience in critical thinking is acceptable, but some common fields of study for law enforcement officers are criminal justice, law, sociology and forensic science.


Candidates for police offer positions are usually expected to have attended a police academy. Training for this specialized role includes learning state, local and constitutional law and civil rights and police ethics.
