How to Become a Police Officer
To become a police officer you usually need a high school diploma or GED, to be at least 21 (some states allow 18–20), a clean record, and a pass on the written, physical, psychological and background checks. Most people go from application to sworn officer in 6–12 months, including a police academy of roughly 4–6 months. If a department hires you first, it typically pays for the academy; self-sponsored academy tuition runs from a few thousand dollars upward.

Steps to become a police officer
Check that you meet the basic requirements
Confirm you are a US citizen, meet your state's minimum age (usually 21, sometimes 18–20), and hold a valid driver's license. Look at the disqualifiers on your target agency's recruiting page: felony convictions, certain misdemeanors, recent drug use and a poor driving record are common ones. If you have something on your record, ask a recruiter before you apply instead of guessing.
Get in shape for the physical test
Find your agency's exact fitness standard. Many use a timed run (often 1.5 miles), push-ups, sit-ups and an obstacle or agility course. Train 4–5 days a week for at least 6–8 weeks before the test date, and practice the events at test pace.
Decide between agency-sponsored and self-sponsored academy
In most departments you apply first, get hired as a recruit, and the agency sends you to the academy on salary. In some states, such as parts of California, Texas and Florida, you can pay your own way through a POST academy first, which can make you more attractive to smaller departments. Compare both before spending money on tuition.
Apply and pass the written exam
Submit applications to several agencies at once, since hiring cycles are slow. The written test usually covers reading comprehension, writing, basic math, memory and judgment. Some agencies use the PELLETB (California) or a vendor test such as FrontLine National (offered through the National Testing Network); buy a study guide or take a practice test for the exact exam named in the posting.
Get through the background check, interview and psych exam
Fill out the personal history packet completely and honestly; omissions disqualify more candidates than past mistakes do. Expect a polygraph or voice stress test in many agencies, an oral board interview, a psychological evaluation and a medical exam with drug screening. Gather your documents early so the investigator is not waiting on you.
Complete the police academy
Basic academy training averages about 21 weeks nationally, though state minimums vary widely. You will study criminal law, patrol procedures, firearms, defensive tactics, emergency driving, first aid and report writing. Show up fit, study every night, and treat inspections and deadlines as part of the test.
Pass the state certification exam
Most states require you to pass a POST certification exam at the end of the academy before you can work as a sworn officer. The exam covers what the academy taught. Your academy staff will schedule it and tell you the passing score.
Finish field training and probation
After the academy you ride with a field training officer for roughly 3–6 months and are graded on real calls. Most agencies keep new officers on probation for 6–18 months. Keep notes, ask questions, and take feedback without arguing.
Find a police academy or criminal justice program
If a department will hire and sponsor you, that is usually the cheapest route; pay for an academy or degree only if your target agencies require or clearly reward it.
- Agency-sponsored police academy (you are hired first, then trained)
- Self-sponsored POST academy at a community college or regional training center
- Associate degree in criminal justice or law enforcement
- Bachelor's degree in criminal justice (for state, federal or promotion paths)
- Police cadet or explorer program for applicants under 21

Exams and how to prepare
Police written entrance exam
Multiple-choice test of reading, writing, grammar, basic math, memory and situational judgment. Agencies use their own test or a vendor test (e.g. PELLETB in California, FrontLine National).
How to prepare: Find the exact test name in the job posting, buy a matching study guide, and take at least two timed practice tests.
Physical ability test (PAT)
Timed fitness events such as a 1.5-mile run, push-ups, sit-ups or an obstacle course with a dummy drag and wall climb.
How to prepare: Train to the agency's published standard 6–12 weeks in advance and practice the events at test pace.
Psychological exam
Written personality and psychological inventories, usually followed by an interview with a psychologist.
How to prepare: Answer honestly and consistently; there is nothing to memorize. Get good sleep before the test.
Oral board interview
A panel of officers or supervisors asks why you want the job and how you would handle scenarios.
How to prepare: Practice answers out loud, know the department's mission and community, and use specific examples from your life.
State POST certification exam
End-of-academy test on law, procedures and skills required for state certification as a peace officer.
How to prepare: Keep up with academy coursework and review the state's learning objectives before the exam.

Police Officer salary and job outlook
Employment of police and sheriff's patrol officers is projected to grow 3% from 2025 to 2035, about as fast as average. BLS expects about 60,100 openings a year for police and detectives combined, mostly to replace officers who retire or leave. Pay is usually higher in large cities and state agencies, and overtime can add significantly.

Frequently asked questions
How long does it take to become a police officer?
Usually 6–12 months from application to graduation. Hiring (tests, background, interviews) takes 2–6 months, and the academy takes about 4–8 months depending on the state. After that, expect 3–6 months of field training and a probation period.
Do you need a college degree to be a police officer?
No, most local agencies require only a high school diploma or GED. Some departments require 30–60 college credits or a degree, and federal agencies and state police often prefer one. A degree can help with promotion later.
How much does police academy cost?
If a department hires you first, the academy is usually free and you are paid while you attend. If you self-sponsor through a community college or regional academy, tuition and gear can range from a few thousand dollars to around $8,000, depending on the state.
What is the age limit to become a police officer?
The minimum is usually 21, though some states and agencies hire at 18–20. Maximum ages vary: some agencies cap entry in the mid-30s to 40s, many have no cap, and federal law enforcement generally sets 37 as the maximum entry age.
Can you become a police officer with a misdemeanor?
Sometimes. A felony disqualifies you almost everywhere, and a domestic violence conviction blocks you from carrying a gun under federal law. Other misdemeanors are judged by type, how long ago they happened, and whether you disclose them honestly.
How much do police officers make?
The median pay for police and sheriff's patrol officers was $76,210 in May 2025, according to BLS. The lowest 10% earned under $47,510 and the top 10% over $115,120. Overtime, shift pay and city size make a big difference.
What is the hardest part of becoming a police officer?
Many candidates say the background investigation and the psychological evaluation are the hardest steps, because small omissions can end your application. In the academy, the physical training and the volume of law to learn are the biggest challenges.
What is the police psychological exam like?
It usually has two parts: written tests such as personality inventories, then an interview with a psychologist who reviews your answers and history. You cannot study for it in the usual sense; answer honestly and consistently.
