What does a police officer do?
Police officers keep communities safe. They patrol neighborhoods, respond to 911 calls, enforce traffic laws, investigate crimes and help people in crisis. On any given shift, an officer might handle a car crash, a domestic dispute, a burglary report, a missing person and a mental health call.
Patrol is the core of the job. Officers drive, walk or bike through assigned areas, watch for problems and respond to calls for service. When they arrive at a scene, they figure out what is happening, keep people safe, give first aid if needed and decide what to do next.
Investigations and paperwork are a big part of the job. Officers interview victims and witnesses, collect evidence, make arrests when needed and write detailed reports. They may testify in court about their cases.
Community work matters too. Officers build relationships with residents, businesses and schools, and they often connect people with social services. Clear communication and good judgment are some of the most important skills an officer can have.
Tools of the job include patrol vehicles, radios, body-worn cameras, computers in patrol cars, firearms and less-lethal tools, handcuffs and first aid kits.
Police officers work for:
- City and town police departments
- County sheriff’s offices
- State police and highway patrol
- College, transit and airport police departments
- Federal law enforcement agencies (usually with more education)
A typical shift
- Attend roll call for briefings and assignments
- Patrol your area and respond to calls for service

Training options: police academy and criminal justice school
Agency-sponsored academy. In many places, you are hired by an agency first, and the agency sends you to a police academy. You are usually paid while you train. This is the most common path in many states.
Self-sponsored academy. In some states, community colleges and regional academies accept recruits who pay their own way before being hired. Graduating can make you more attractive to agencies, since they do not have to pay for your training. Costs vary by state and school.
Criminal justice degree. Community colleges and universities offer associate and bachelor’s degrees in criminal justice. A degree is not always required, but it can help you get hired, earn higher pay at some agencies and qualify for promotions. Federal agencies usually require a bachelor’s degree.
Military experience. Many agencies value military service, and some give hiring preference to veterans.
Certification and licensing by state
Every state sets its own standards for police officers, usually through a Peace Officer Standards and Training (POST) board or similar agency. The POST board sets minimum academy hours, required courses and certification exams.
Common state requirements include:
- Meeting minimum hiring standards, such as age, education and a background check
- Completing an approved basic law enforcement academy
- Passing the state certification exam, if your state has one
- Completing in-service training each year to keep your certification
If you move to another state, you usually need to meet that state’s requirements. Some states offer a shorter process for certified officers from other states, while others require a full academy.
Specializations and where they lead
- Detective or investigator. Investigate crimes like burglary, fraud or homicide. Usually requires patrol experience.
- K-9 officer. Work with a trained police dog to find drugs, track suspects or search buildings.
- SWAT or tactical officer. Respond to high-risk situations as part of a specialized team.
- Traffic or school resource officer. Focus on traffic safety or work in schools with students and staff.
- Sergeant, lieutenant and beyond. Experienced officers can be promoted to supervise and lead.
How to choose a criminal justice school or police academy
The right program prepares you for hiring and a long career in law enforcement. Ask these questions:
- Is the academy approved by my state’s POST board? Only approved academies lead to certification.
- Can I attend as a self-sponsored recruit? Ask about costs and whether local agencies hire graduates.
- What is the graduation and certification exam pass rate? Ask for recent results.
- How much hands-on training is included? Ask about firearms, defensive tactics, driving and scenario training.
- For degree programs, is the school accredited? Accreditation affects federal financial aid (FAFSA) and credit transfer.
- Does the program include internships or ride-alongs? Real-world exposure helps you decide and get hired.
- What job placement help do you offer? Ask which agencies hire graduates.
