How to become a police officer

1. 1Meet the minimum standards

   Time: Before you applySources 1, 3

   Most agencies require you to be at least 21 by the time you are appointed, hold a high school diploma or GED, have a valid driver's license and be legally able to work in the US; many require citizenship, and federal officers must be citizens. California POST also requires a background investigation showing good moral character. A felony conviction or recent drug use usually disqualifies you, so read each agency's rules before applying.

2. 2Consider college or military service

   Time: 0-4 years (optional for many agencies)Cost: $4,680/yr median public in-state tuition (associate)Sources 1, 6, 8

   A degree is not required by most local departments, but some ask for college credits, and federal agencies and promotion to lieutenant or above often call for a bachelor's degree. Criminal justice is common, though any major works. In Texas, applicants with an associate degree or 60 college hours, or two years of active military service with an honorable discharge, can be licensed at 18 instead of 21. Military service and a second language also help applicants stand out.

3. 3Get through the hiring process

   Time: Often several monthsSources 1, 3

   Expect a written test, a physical ability test of running, strength and agility, an oral board interview, and a detailed background investigation that covers your employment, finances, driving record and references. Many agencies add a polygraph and drug test. You also need medical and psychological evaluations; California requires both. Apply to several agencies at once, because each process takes months and many applicants are screened out.

4. 4Complete the police academy

   Time: About 5 months full timeCost: Usually paid by the agencySources 2, 4

   State and local academies required an average of 806 hours of basic training in 2022, according to the Bureau of Justice Statistics. Training covers criminal and constitutional law, patrol, traffic stops, firearms, defensive tactics, first aid, emergency driving and report writing. California's Regular Basic Course is at least 680 hours across 43 learning domains. About one in seven recruits did not finish in 2022.

5. 5Finish field training and probation

   Time: Several months to a yearCost: PaidSources 1, 4, 5

   After graduation, you ride with a field training officer who coaches and evaluates you on real calls before you patrol alone. You then serve a probation period, during which a department can let you go more easily. Once you pass, you become eligible to test for specialized units and, later, promotion. Keep up with required continuing training; Texas officers, for example, need 40 hours every 24 months.

Programs, tuition and graduates’ earnings

U.S. Department of Education, College Scorecard (most recent cohorts, released 2026-10-15). Scorecard groups programs by 4-digit field, so a row can include related programs. Tuition is the median published undergraduate tuition and fees of the colleges offering the program (shown only for undergraduate credentials); debt is the median of programs’ median federal loan debt at completion; earnings are the national median for the field and credential four years after completion.

Requirements differ by state. Check your state’s rules in the CareerOneStop License Finder (U.S. Department of Labor) before you enroll.

Judgment under pressure

Officers often have seconds to decide whether to talk, wait, call for backup or use force, and those decisions are reviewed afterward.

De-escalation and communication

Most calls are settled by talking: calming an angry driver, getting a frightened witness to explain what happened or persuading someone in crisis to accept help.

Report writing

Prosecutors build cases from an officer's report, and vague or inaccurate writing can get charges dropped or cause trouble on the witness stand.

Physical fitness

You must pass a fitness test to get in, and on the job you may chase, restrain or carry people while wearing heavy gear.

Integrity

Officers handle evidence, money and private information, and a single credibility problem can end a career and taint past cases.

Pay above the all-jobs median vs. cost

Low: $0 when a department hires you first and pays for the academy, which is common. High: an associate degree in criminal justice, 2 years x College Scorecard median public in-state tuition of $4,680 = $9,360, for agencies that want college credit. Not included: tuition at self-sponsored academies (varies by state and school), equipment, and living costs during an unpaid academy.

Rough guide only: ignores taxes, aid, interest and earnings given up during training. How we calculate it.

• Detective$93,790 median

  Most departments promote detectives from patrol after several years, through a written exam, interview or selection process.

• Sergeant, lieutenant or captain

  Moving up to sergeant and beyond is usually decided by promotional tests and your service record, and command ranks such as lieutenant can call for a bachelor's degree.

• Private investigator$51,220 median

  Former officers often move into private investigations after retiring, which in most states takes a separate private investigator license.

• Federal agent

  Federal agencies hire experienced officers, but usually require a bachelor's degree, U.S. citizenship and their own academy; the FBI also requires prior work experience.
