Minimum Age to Become a Police Officer in the U.S.: 18–21, Varies by State

Typical Range

Most states set the minimum age between 18 and 21:

• 18: Some states (e.g., Montana, parts of rural Midwest)
• 19–20: Several states
• 21: Most common (CA, NY, TX, FL, IL, etc.)

Universal Requirements (Beyond Age)

• High school diploma or GED
• U.S. citizenship (or permanent resident in some states)
• Clean criminal record
• Valid driver's license
• Physical fitness / medical / psychological exams
• Written entrance exam
• Police academy training (12–28 weeks)

Competitive Process

Hiring takes 3–9 months. Many departments prefer candidates with some college, military service, or life experience—so 21+ is common even where 18 is legal minimum.
