CDCR Correctional Officer Written Selection Exam · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Reading Comprehension and Information Retention

  • Identify the main idea, supporting details, and author's purpose in 12 short passages drawn from policy-style and narrative text

  • Paraphrase each paragraph of a two-page passage in one sentence to build retention habits

  • Practice active-recall techniques (summarize-without-looking, keyword jotting) after each reading block

  • Log every missed question with the reason for the miss (detail confusion, inference, vocabulary, or time pressure)

Your checkpoint

A completed error log covering 40 reading questions plus a one-page summary of your three most frequent miss types.

Week 2

Reading Comprehension and Information Retention & Written Communication (grammar, usage, spelling, sentence clarity)

  • Read two multi-paragraph passages under a 10-minute time limit each and answer detail and inference questions without re-reading the full text

  • Distinguish stated facts from inferences in 20 practice items and justify each choice in writing

  • Review the eight parts of speech and label them in 15 sentences

  • Correct run-on sentences and fragments in a 20-sentence editing exercise

Your checkpoint

A 25-question reading-and-inference quiz scored at 80% or better, with written justifications for every answer.

Week 3

Reading Comprehension and Information Retention & Written Communication (grammar, usage, spelling, sentence clarity) & Mathematical Reasoning (arithmetic, percentages, ratios, basic applied problems)

  • Summarize three 400-word passages from memory in three sentences each to test retention

  • Apply subject-verb agreement and pronoun agreement rules to 30 practice sentences

  • Drill addition, subtraction, multiplication, and division of whole numbers and decimals without a calculator

  • Solve 15 order-of-operations problems and check each answer by a second method

Your checkpoint

A timed 30-minute mixed set (10 reading items, 10 grammar items, 10 arithmetic items) with a recorded score and time per section.

Week 4

Written Communication (grammar, usage, spelling, sentence clarity) & Mathematical Reasoning (arithmetic, percentages, ratios, basic applied problems)

  • Edit a one-page incident-style narrative for grammar, spelling, and clarity, producing a clean revised draft

  • Convert between fractions, decimals, and percents in 30 items

  • Solve 20 percent problems in applied contexts (staffing counts, budget changes, population figures)

  • Set up and solve 15 ratio and proportion problems, including unit-rate comparisons

Your checkpoint

A 30-question written-communication-and-math assessment scored at 80% or higher, with corrections for every missed item.

Week 5

Mathematical Reasoning (arithmetic, percentages, ratios, basic applied problems) & Analytical and Logical Reasoning

  • Solve 20 multi-step word problems involving averages, totals, and remaining quantities, showing each step

  • Estimate answers before calculating to catch arithmetic errors, applying this to 15 problems

  • Identify the pattern or rule in 15 number and letter series

  • Complete 15 deductive-logic items (if-then statements, syllogisms) and write the reasoning chain for each

Your checkpoint

A one-page formula and strategy sheet for math word problems plus a 25-item logic-and-math set scored at 75% or better.

Week 6

Analytical and Logical Reasoning

  • Draw valid conclusions from 20 sets of stated rules without adding outside assumptions

  • Distinguish necessary from sufficient conditions across 15 conditional-reasoning items

  • Order and schedule tasks under constraints in 10 sequencing puzzles

  • Write a short explanation of why each incorrect option in 15 items is wrong

Your checkpoint

A timed 30-question logical-reasoning practice test with a written rationale for every answer, correct or incorrect.

Week 7

Interpersonal Skills and Situational Judgment & Analytical and Logical Reasoning

  • Apply a four-step situational-judgment method (identify the problem, weigh safety and policy, choose the least-escalating effective action, check consequences) to 15 scenarios

  • Analyze 10 interpersonal scenarios for de-escalation, chain of command, and documentation considerations

  • Review chain-of-command and report-writing expectations and list five behaviors that sustain professionalism under stress

  • Re-work 10 previously missed analytical-reasoning items untimed

Your checkpoint

A written response plan for five situational scenarios, each under 150 words and scored against your own four-step checklist.

Week 8

Reading Comprehension and Information Retention & Written Communication (grammar, usage, spelling, sentence clarity) & Mathematical Reasoning (arithmetic, percentages, ratios, basic applied problems) & Analytical and Logical Reasoning & Interpersonal Skills and Situational Judgment

  • Take two full-length timed practice tests under exam conditions and record domain-by-domain scores

  • Re-drill the 25 highest-frequency missed items from the error log until each is answered correctly twice in a row

  • Review the formula sheet, grammar rules, and situational-judgment checklist in a single 60-minute session

  • Build a final week-of-exam checklist covering sleep, timing strategy, and a skip-and-return plan for hard questions

Your checkpoint

Two completed timed practice tests with a score comparison showing improvement from test one to test two.

Milestones

Week 4: Score 80% or better on the combined grammar-and-math assessment and have at least 60 logged reading items in the error log.

Week 6: Answer 75% or more of analytical-reasoning practice items correctly with a written rationale for each.

Week 7: Produce all five situational-judgment response plans and confirm each meets the four-step method checklist.

Week 8: Exceed your week-8 first practice-test score on the second attempt and clear 80% overall.
