Step 3: For prospective police detectives: Enroll in a police academy and get investigative experience (one to three years)

For those looking to become police detectives—an option that can be more lucrative than becoming a private investigator (PI)—enrolling in a police academy is the next step.

Although requirements vary by department and region, to qualify for a police academy, candidates must be US citizens; be at least 18 years old; possess a driver’s license; have no felony convictions; and have some college experience.

Please note that state and federal agencies typically require at least four years of undergraduate education. Police academy programs generally last six to eight months with specialized training in firearm use, patrol procedures, ethics, self-defense, report-writing, CPR and first aid, physical fitness, and emergency response.

After the academy, aspiring detectives are urged to take on advanced training and responsibilities in investigative units to build their resumes. There are various branches of investigation including homicide, surveillance, fraud, computer crimes, financial crimes, and missing people.
