The CO written exam typically covers reading comprehension (understanding facility policies and procedures), basic mathematics (count calculations, time math, ratios), situational judgment (realistic scenarios testing policy knowledge and ethical decision-making), and sometimes grammar or report writing. The exact content, length, and passing score vary by state and agency. Federal Bureau of Prisons candidates take a different assessment through the USAJOBS system. Always obtain your specific agency's candidate handbook to confirm what is tested.

The CO written exam is generally considered moderately difficult for candidates who prepare adequately. Reading comprehension is the highest-weighted section and is highly improvable with practice. Mathematics is at a basic arithmetic level — no advanced math required. Situational judgment is the section candidates most often misjudge, because the "right" answer is based on policy and minimum-force principles rather than personal instinct. Candidates who score below passing on their first attempt most often cite insufficient reading comprehension practice and unfamiliarity with the situational judgment framework. Consistent practice with a PDF and timed tests significantly improves pass rates.

Minimum passing scores vary by agency and state. Most civil service CO exams require a passing score between 70% and 80% correct to remain on the eligible list. Some competitive agencies place candidates on a ranked list by score, meaning a higher score results in a better hiring position even above the minimum passing threshold. Federal BOP assessments use a different scoring system. Always check your specific agency's job announcement for the minimum passing score and how candidates are ranked.

Common disqualifiers include: felony conviction at any time, misdemeanor conviction involving moral turpitude or domestic violence, dishonorable military discharge, recent drug use (typically within 2 to 5 years, depending on substance and agency), habitual marijuana use, significant credit or financial problems (debt, bankruptcy), a pattern of dishonesty discovered during the polygraph or background investigation, and failure to meet vision, hearing, or physical fitness standards. The psychological evaluation can also result in a suitability disqualification. Each agency sets its own standards — check your state DOC's specific disqualifier list before applying.

Correctional officer salaries vary widely by state, county, and level of government. Entry-level state CO salaries range from approximately $38,000 (lower-cost southern states) to over $72,000 (California, New York) annually, plus benefits. Federal Bureau of Prisons officers start at GS-5 or GS-6 ($34,000 to $42,000), with additional locality pay in high-cost areas and federal benefits including a defined-benefit pension. Most agencies provide uniform allowances, overtime opportunities, and shift differentials for evening and overnight assignments. After several years, experienced officers who promote to sergeant or lieutenant earn $55,000 to $100,000+ depending on location.

The full correctional officer hiring process — from application to academy start date — typically takes three to twelve months. The sequence usually includes: application submission and written exam, physical fitness test, background investigation (the longest phase, often two to four months), psychological evaluation, medical exam and drug screen, conditional offer, and pre-employment training academy. Background investigations for federal positions or agencies in competitive markets take longer. Candidates are advised to apply to multiple agencies simultaneously to reduce waiting time and maintain momentum in the process.
