How to become a correctional officer

1. 1Meet the basic requirements

   Time: Before you applySources 1, 2, 5

   You need a high school diploma or GED and must be at least 18, though some agencies set the minimum at 21. Citizenship or work authorization and a clean record matter: in Texas, for example, any felony, a domestic violence conviction, or a Class A misdemeanor in the past 10 years disqualifies you. Federal prisons ask for a bachelor's degree or three years of qualifying experience and generally hire before your 37th birthday, with exceptions for some preference-eligible veterans and prior federal law enforcement service.

2. 2Apply to a state, county or federal agency

   Time: 1-4 weeksSources 2, 3

   Choose the employer first: a state department of corrections for prisons, a sheriff's office or county for jails, or the Federal Bureau of Prisons through USAJOBS. Many agencies post openings year-round. Expect a written or computer-based test at some agencies, plus a panel interview. Read the posting closely for the minimum age, education and residency rules, because they differ from one agency to the next and change with hiring needs.

3. 3Pass the background check, drug test and medical exam

   Time: 1-3 monthsSources 2, 3, 5

   Agencies check criminal history, references, past employers and sometimes credit; the federal process includes National Crime Information Center and credit checks. You will take a drug test and a medical exam, and usually a physical agility test. Be truthful on every form, since an omission found during the background investigation can end your application even when the underlying issue would not have.

4. 4Complete the training academy

   Time: 3 weeks to several monthsCost: Paid by the agencySources 3, 4, 2

   Academies teach facility rules and security procedures, use of force, self-defense, restraints, report writing, first aid and how to handle mental health crises. The Texas prison system's pre-service academy runs about 240 hours over roughly six weeks, with three physical agility tests during the course. New federal officers attend the three-week Introduction to Correctional Techniques at the Federal Law Enforcement Training Center in Glynco, Georgia, which covers firearms, self-defense, a written test and the Physical Abilities Test.

5. 5Finish field training and probation

   Time: 6-12 monthsSources 1, 2

   After the academy you shadow experienced officers on real posts before working alone. Agencies keep new officers on probation for a set period; at the Federal Bureau of Prisons it is one year. Shifts can fall on nights, weekends and holidays. Where the state requires certification, it is usually granted once you complete the approved academy and meet the state's other conditions.

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.

Calm under pressure

Officers are insulted, tested and sometimes attacked, and reacting with anger can turn a tense unit into a riot.

Verbal de-escalation

Talking someone down before a dispute becomes a fight is safer for everyone than using force.

Attention to detail

A miscounted unit, a door left open or a missed piece of contraband can lead to an escape or an assault.

Physical fitness

You may need to stand for a full shift, run to an emergency on another unit and restrain a resisting person.

Clear report writing

Incident reports are used in disciplinary hearings, lawsuits and criminal cases, so they must be accurate and specific.

Firm, fair consistency

Applying the rules the same way to everyone builds the credibility that keeps a housing unit orderly.

O*NET 31.0 rates these skills as most important for the occupation: active listening, monitoring, speaking, critical thinking, reading comprehension.

Pay above the all-jobs median vs. cost

Low: $0, because state, county and federal agencies hire you first and pay you while you attend their academy (Texas, for example, puts trainees on the state payroll from day one). High: one year of a criminal justice or corrections certificate at the College Scorecard median public in-state tuition of $4,536, for applicants who want college credit before applying. Not included: a bachelor's degree, which only federal and some state agencies require or reward.

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

• Sergeant, lieutenant or captain

  Promotion inside the agency usually takes several years of service, a promotional exam or board, and a strong record; higher ranks may prefer a degree.

• Police officer or deputy sheriff$76,210 median

  Corrections experience helps with a move to patrol, but you must meet the police agency's own standards and finish a peace officer academy.

• Detective or criminal investigator$93,790 median

  Some officers join prison intelligence or investigations units, then move to detective or federal investigator roles that often require a degree.

• Private investigator$51,220 median

  Report writing, interviewing and investigative experience carry over; private investigator licensing is set by each state, so check its requirements before applying.
