In prison, CO means correctional officer. It’s the standard term, used by staff and inmates alike, for the uniformed employee who supervises people in custody, enforces facility rules, and keeps the institution secure around the clock. The older phrase “prison guard” points at the same job, but it undersells the range of what a CO actually handles.
What a CO Does on Shift
A correctional officer’s work is a continuous loop of supervision, searches, movement, and paperwork. On a typical shift, a CO will:
- Supervise inmates during meals, recreation, work assignments, and time in housing units.
- Search people and living quarters for contraband such as weapons, drugs, and cell phones.1National Institute of Justice. Contraband Detection and Control
- Escort inmates to medical appointments, court, visitation, or transfers.
- Respond to fights, medical emergencies, fires, and attempted escapes, often within seconds of an alarm.
- Write incident reports documenting rule violations and use-of-force events, records that can later be used in disciplinary hearings or court.
- Watch for shifting moods and tensions in a unit and de-escalate disputes before they turn physical.
A good CO reads body language, tracks allegiances inside a housing unit, and notices when something feels off before it becomes an incident. Contraband work alone is constant. Drugs, improvised weapons, and phones move into facilities through mail, visitation, and sometimes staff, and the National Institute of Justice notes that detecting and confiscating contraband quickly is key to preventing drug abuse, violence, and further crimes.1National Institute of Justice.

Prisons never close, so the work runs in rotating shifts covering every hour of the day, including weekends and holidays, with mandatory overtime common where staffing is short.2U.S. Bureau of Labor Statistics. Correctional Officers and Bailiffs
How a CO Differs From Other Prison Staff
A prison runs on more than COs. Wardens oversee the entire institution. Administrative staff handle budgets and scheduling. Medical personnel provide healthcare. Counselors and case managers focus on rehabilitation programming and reentry planning.
What sets a CO apart is direct, continuous supervision. They are physically present on the housing units, in the dining halls, and along the perimeters, every shift. A counselor might see a particular inmate once a week; a CO interacts with the same population every day. That constant contact means COs often know an inmate’s patterns better than anyone else on staff, and their observations carry weight in classification decisions and disciplinary hearings.
The Risks of the Job
Correctional officers have one of the highest rates of injuries and illnesses of any occupation tracked by the Bureau of Labor Statistics, with confrontations with inmates as the primary cause. Safety gear helps, but physical risk is built into the role. BLS describes the environment plainly: “Working in a correctional institution can be stressful and dangerous.”2U.S. Bureau of Labor Statistics. Correctional Officers and Bailiffs
The psychological load is just as real. A study in the Journal of Traumatic Stress found that more than half of jail officers in its sample screened positive for PTSD, a rate notably higher than the roughly 35% reported among police officers. Burnout, emotional exhaustion, and routine exposure to violence drive a significant share of the profession’s turnover.
How Someone Becomes a CO
Most state and local agencies require a high school diploma or GED, a minimum age of 18 or 21, and a background check.2U.S. Bureau of Labor Statistics. Correctional Officers and Bailiffs Physical fitness testing is common. Federal positions through the Bureau of Prisons add stricter requirements, including education or work experience thresholds and medical standards for vision, hearing, and emotional stability.3U.S. Office of Personnel Management.

After hiring, new officers go through a training academy before working on the floor. State academies vary in length and cover security procedures, self-defense, de-escalation, report writing, and corrections law. The Bureau of Prisons requires all new institution employees to complete a three-week in-residence course called “Introduction to Correctional Techniques” within 60 days of joining.4Federal Bureau of Prisons. Training Centers On-the-job training follows, pairing new officers with experienced staff.
Pay and Job Outlook
The median annual wage for correctional officers is $53,300, or about $25.63 per hour, according to the most recent Bureau of Labor Statistics data.5U.S. Bureau of Labor Statistics. Correctional Officers and Jailers Federal positions generally pay more than state or local ones, and overtime can push totals higher. Pay rises with promotion through a rank structure that typically runs from officer to sergeant, lieutenant, captain, and into administrative leadership.
Overall employment of correctional officers is projected to decline about 7 percent from 2024 to 2034, a loss of roughly 30,100 positions, as some states see falling incarceration rates and tighter budgets.2U.S. Bureau of Labor Statistics. Correctional Officers and Bailiffs High turnover means facilities still hire frequently to replace departing staff, so openings remain common even as the total number of jobs shrinks.
