CDCR Correctional Officer Written Selection Exam common mistakes
CDCR Correctional Officer Written Selection Exam · Understand the traps and how to avoid them.
Choosing the answer that matches what the candidate already believes about the passage's topic, instead of going back into the passage and finding the sentence that proves the answer.
The passages are about familiar subjects such as inmate handling, report writing, or safety rules, so the brain auto-completes details from general knowledge and the option 'feels' right without being checked.
What to do instead
For every reading item, point to a specific line in the passage before selecting. If no line supports the option, eliminate it, even if it sounds true in real life.
Reading a passage that contains several rules, steps, or conditions once, then answering detail and sequencing items from memory without recording anything.
Working memory drops the third and fourth items in a list, so the candidate remembers the general topic but swaps the order, the numbers, or who is responsible for what.
What to do instead
Use the scratch materials: write a three-to-five word tag for each paragraph, or list each condition as a short bullet as it appears, then match each question back to the list.
Writing or selecting sentences that join two complete thoughts with only a comma, or that lack a subject or verb entirely.
People write the way they speak, and in speech a pause does the work a period, semicolon, or conjunction should do on paper, so run-ons and fragments read as correct to the ear.
What to do instead
Test each clause for its own subject and verb. If both halves pass, separate them with a period, a semicolon, or a comma plus a conjunction such as 'and', 'but', or 'because'.
Matching the verb to the noun closest to it rather than to the real subject, and using pronouns that could refer to more than one person.
Phrases inserted between subject and verb ('the officer, along with two inmates, ...') pull the ear toward the nearer noun, and pronouns like 'he', 'she', or 'they' get used without checking how many people were named earlier.
What to do instead
Cross out any phrase between the subject and the verb, then read subject and verb together. For pronouns, replace the pronoun with the name in your head: if two names fit, the sentence is ambiguous and needs the noun repeated.
Computing a percentage increase or decrease against the wrong starting amount, or adding the percentage to the wrong figure.
The larger or more recently mentioned number attracts attention, and candidates apply the rate to it before deciding which quantity is the base the change is measured from.
What to do instead
Before calculating, write two labels on the scratch sheet: 'original = ___' and 'change = ___'. Percent change is always the change divided by the original, and a discount comes off the original price, not off the sale price.
Multiplying or dividing quantities that are in different units, and submitting an answer without asking whether the size of it makes sense.
Under time pressure candidates grab the two numbers in the problem and combine them, skipping the step of converting minutes to hours, ounces to pounds, or checking whether the result is plausible.
What to do instead
Convert everything to one unit before writing the equation, and label each number with its unit. Then do a rough estimate first: if the exact answer is far from the estimate, redo the work rather than moving on.
Treating a conditional statement as reversible, or reading 'some' as 'all' when drawing a conclusion.
'If a visitor has no identification, the visit is denied' invites the false reverse, 'the visit was denied, so the visitor had no identification', because the two events are associated in the mind.
What to do instead
For each conclusion, try to build one scenario where the stated facts are all true but the conclusion is false. If such a scenario exists, the conclusion does not follow.
Rejecting or accepting an answer because of real-world knowledge, personal opinion, or how a real institution works, instead of using only the facts given in the item.
Candidates with prior work or life experience trust that experience over the premises, and items that ask 'if the statements are true' punish exactly that instinct.
What to do instead
Treat the stated facts as the only evidence in the room. Ask 'is this option supported by these sentences?' rather than 'is this option true in general?'
Choosing the harshest available response, or the one that avoids acting at all, instead of the response that follows procedure, keeps safety first, and documents the event.
Candidates assume a correctional setting rewards toughness, or they fear making an error, so they pick an extreme that ignores policy, chain of command, or the duty to report.
What to do instead
Score each option on three tests: does it protect safety, does it follow policy and notify the right supervisor, and is it recorded? Prefer the option that passes all three over any option that is merely firm or merely passive.
Selecting the answer that keeps a coworker's or a supervisor's mistake quiet, or that handles a problem informally without reporting it.
Loyalty and fear of retaliation feel like teamwork, so covering for a colleague or quietly fixing an issue seems like the low-risk, cooperative choice.
What to do instead
In any item where a rule was broken, information was concealed, or a safety issue exists, the correct answer includes reporting through the chain of command. Options that resolve the matter privately are distractors even when they feel considerate.
