Corrections officer written exams are administered by individual state and county Departments of Corrections, so the exact format, number of questions, and time limit varies. New York's exam, for example, is 100 questions covering Applying Written Information, Observing and Recalling Facts, Preparing Written Material, and Understanding Written Information. New Jersey uses a Cognitive Ability Test covering written expression, problem sensitivity, and reasoning. California's CDCR exam covers Written Comprehension, Mathematics, and Situational Judgment in 53 questions.
Despite the differences, nearly every version draws from the same underlying skill set:
Because these five skill areas recur across nearly every version of the exam nationwide, building genuine ability in each one, rather than memorizing one state's exact question bank, transfers directly to whichever specific test you end up taking.

Study Guide
About the real test
Corrections officer exams vary by state and county, but nearly every version tests the same 5 core skills: Reading Comprehension, Basic Math, Memory and Observation, Situational Judgment, and Written Communication.
Check your specific agency's exact format
New York, New Jersey, and California each structure their exams differently. This practice builds the common underlying skills, but always confirm your specific state or county's format and study guide.
Memory and Observation questions reward careful first reads
Read the scenario once, carefully, noting names, times, and numbers. Most questions can be answered correctly without rereading if you catch the details the first time.
Situational Judgment questions almost always reward following procedure over shortcuts
When an option involves reporting through proper channels versus handling something informally or alone, the proper-channels option is usually correct.
