How Long Does It Take to Become a Police Officer?

Quick Answer

Becoming a police officer usually takes 6 to 18 months from the time you apply to the day you begin solo patrol. The largest chunks are the hiring process (2–6 months), the police academy (4–6 months / roughly 800 hours of training), and field training (3–4 months). If a college degree is required or preferred, add the time to earn it.

Timeline by Stage

Stage	Typical Duration	Notes
Application & written exam	2–6 weeks	Includes initial screening
Physical fitness test	1 day	Push-ups, run, agility
Background investigation	2–4 months	Often the longest wait
Polygraph, psych & medical exams	2–4 weeks	Scheduled after background
Police academy	4–6 months	~600–1,000 training hours
Field training (FTO)	3–4 months	Riding with a senior officer
Probationary period	6–18 months	Sworn but still evaluated

Education Requirements

Most U.S. agencies require a high school diploma or GED at minimum, plus being at least 21 years old (some hire at 18–20 for cadet roles). Federal agencies and some larger departments prefer or require a 2- or 4-year college degree in criminal justice or a related field.

• High school diploma only: No added time beyond the hiring process
• Associate degree: ~2 years
• Bachelor's degree: ~4 years

A degree is not always mandatory, but it can speed promotion and is required for many specialized or federal positions.

What Happens at the Police Academy

The academy is a full-time, often paramilitary training program. Recruits study criminal law, patrol procedures, defensive tactics, firearms, emergency vehicle operation, first aid, and de-escalation. Programs range from about 13 to 30 weeks depending on the state and agency. Recruits are typically paid a salary during the academy.

Factors That Affect the Timeline

The Hiring Backlog

The background investigation is often the biggest variable. Departments verify employment, references, credit, criminal history, and sometimes interview neighbors — this alone can take 2–4 months.

Academy Availability

Many academies run only a few classes per year. If you're hired between sessions, you may wait weeks or months for the next class to start.

State POST Standards

Each state's Peace Officer Standards and Training (POST) commission sets minimum training hours, so academy length varies widely by state.

Prior Experience

Military veterans or those with prior law-enforcement or corrections experience may move through parts of the process faster.

How to Speed Up the Process

• Apply to multiple departments at once to improve your odds and timing.
• Get your paperwork ready early — birth certificate, transcripts, driving record, and references speed the background check.
• Stay in shape so the physical fitness test is never a bottleneck or a reason to restart.
• Be honest on your application and polygraph — discrepancies trigger delays or disqualification.
• Consider a cadet or Explorer program if you're under 21, so you're ready to be hired the moment you're eligible.

Bottom Line

Expect roughly a year on average — about 6 months if a department is hiring quickly and you sail through screening, or up to 18 months if the background check is slow or you're waiting for an academy class. Earning a required college degree adds 2–4 years on top of that.
