- The 5 W's and H of a police report
- Who, What, When, Where, Why, and How — the facts every complete report must answer.
- Combine separate quantities into one total
- Add the parts together (addition).
- Find how many remain after some are removed
- Subtract (take the smaller amount away from the larger).
- Find the total of many equal groups
- Multiply the size of one group by the number of groups.
- Split an amount evenly among people
- Divide the total by the number of people.
- Distance = ?
- Distance = rate × time.
- Average speed (rate)
- Distance ÷ time. 210 miles ÷ 3 hours = 70 mph.
- Average (mean) of a set of values
- Add all the values, then divide by how many values there are.
- Convert ¼ to a percent
- 25%.
- Convert ½ to a percent
- 50%.
- Convert ¾ to a percent
- 75%.

- Convert ⅒ to a percent
- 10%.
- Convert ⅓ to a percent
- About 33% (33.3…%).
- Convert ⅛ to a percent
- 12.5%.
- Find a percent of a number
- Turn the percent into a decimal and multiply by the whole. 20% of 150 = 0.20 × 150 = 30.
- Find what percent one number is of another
- Divide the part by the whole, then multiply by 100.
- Percent change (increase or decrease)
- Change ÷ original × 100. From 40 to 50 is 10 ÷ 40 = 25% increase.
- Quick way to take 10% of a number

- Main idea of a passage
- The single most important point the passage is making — what it is mostly about.
- Supporting detail
- A specific fact, example, or reason that backs up the main idea.
- Inference
- A conclusion you reach by combining stated facts with logic — what the passage implies but doesn't say outright.
- Vocabulary in context
- Figuring out a word's meaning from the surrounding sentence rather than a dictionary.
- First rule of reading-comprehension answers
- Answer only from the passage — not from outside knowledge or assumptions.
- Most common wrong-answer trap
- A choice that adds a fact the passage never stated, or contradicts it.
- How to find the main idea fast
- Read the first and last sentences and ask 'what is this mostly about?'
- 'Stated' vs 'implied' question
- Stated answers appear word-for-word; implied (inference) answers follow logically from the text.
- Why read the question before the passage?
- So you know whether you're hunting for the main idea, a detail, or an inference.
- Fact vs. opinion in a passage
- A fact can be verified; an opinion expresses a belief or judgment ('best,' 'should').
- 'According to the passage…' means
- Pick the choice the text directly supports — do not bring in outside information.
- Author's purpose
- The reason the passage was written — usually to inform, persuade, instruct, or describe.
- Signal words for sequence/order
- First, next, then, after, before, finally — they show the order events happened.
- Signal words for cause and effect
- Because, since, therefore, as a result, so — they link a cause to its effect.
- Signal words for contrast
- However, but, although, on the other hand — they mark a change or exception.
- Best way to handle a long policy passage
- Skim for structure, then re-read only the part that answers the specific question.
- 'Which statement is true based on the passage?'
- Verify each choice against the exact wording; eliminate any that overstate or aren't supported.
- Tone of a passage
- The author's attitude — e.g., neutral, urgent, formal — shown by word choice.
- Drawing a conclusion
- Combine the stated details to reach a result the passage logically leads to.
- If two answers seem correct…
- Choose the one that more completely and exactly matches the passage; reject the one that adds anything extra.
- Topic sentence
- The sentence (often first) that states the paragraph's main point.
- Summarizing a passage
- Restate the main idea and key supporting points in a few words, leaving out minor details.
- Context clue: definition
- The sentence defines or restates a hard word nearby ('a warrant, an order from a judge…').
- Context clue: contrast
- An opposite word signals the meaning ('unlike the calm crowd, the suspect was agitated').
- Why eliminate wrong answers first?
- Crossing out unsupported choices narrows it to the answer the text actually backs.
- 'Primarily' or 'mainly' in a question
- Asks for the overall main idea, not one small detail.
- Reading a witness statement
- Track who said what; don't confuse the witness's account with the officer's observation.
- Detail question strategy
- Scan the passage for the key word in the question, then read that sentence carefully.
- Implied main idea
- When the main point isn't stated, infer it from how the details add up.
- Paraphrase
- Restating a sentence in different words while keeping the same meaning.
- Why not rely on memory for a passage?
- Always go back and check the text — small wording differences change the right answer.
- Distinguish relevant from irrelevant detail
- Keep details that answer the question; ignore facts that don't bear on it.
- 'Except' or 'NOT' in a question
- Flip your logic — you're looking for the one choice the passage does NOT support.
- Reading a department policy correctly
- Apply the rule exactly as written; don't add exceptions the policy didn't state.
- Subject–verb agreement
- The verb must match the subject in number: a singular subject takes a singular verb (The officer writes; The officers write).
- When are commas used in a series?
- To separate three or more items: 'the suspect, the witness, and the victim.'
- Comma after an introductory clause
- Use one: 'Although it was late, the officer continued the search.'
- Comma in direct address
- Set off the name: 'Sir, please remain in your vehicle.'
- Correct spelling: warrant
- W-A-R-R-A-N-T (not 'warrent').

- Correct spelling: definitely
- D-E-F-I-N-I-T-E-L-Y (no 'a').
- Correct spelling: occurred

- P-U-R-S-U-I-T.
- Hyphen in a compound modifier
- Use one before a noun: 'a split-second decision,' 'a well-known suspect.'
- Exclamation point — when?
- For a command or strong emotion: 'Stop or I will fire!' Use sparingly in reports.
- Their / there / they're
- Their = possession; there = place; they're = they are.
- Your / you're
- Your = belonging to you; you're = you are.
- Its / it's
- Its = belonging to it; it's = it is.
- To / too / two
- To = direction/infinitive; too = also/excessively; two = the number 2.
- Affect / effect
- Affect is usually a verb (to influence); effect is usually a noun (a result).
- Then / than
- Then = time/sequence; than = comparison.
- Run-on sentence
- Two complete sentences joined with no proper punctuation — split them or use a semicolon/conjunction.
- Sentence fragment
- An incomplete sentence missing a subject or verb — fix by completing the thought.
- Capitalize proper nouns
- Names, streets, cities, days, and titles before a name: 'Officer Diaz on Elm Street.'
- Apostrophe for possession
- Add 's to show ownership: 'the officer's report,' 'the witness's statement.'
- Semicolon — when?
- To join two closely related complete sentences: 'No fire was found; the building was evacuated.'
- Subject–verb with 'each' / 'every'
- They are singular: 'Each officer files a report,' 'Every vehicle was searched.'
- Double negative — avoid
- 'didn't see nothing' is wrong; write 'didn't see anything.'
- Parallel structure
- Keep list items in the same form: 'searched the car, questioned the driver, and filed a report.'
- Pronoun agreement
- A pronoun must match its noun: 'each witness gave his or her account.'
- Clear vs. unclear sentence
- A clear sentence has one obvious meaning; rewrite anything a reader could read two ways.
- Active vs. passive voice in reports
- Prefer active ('Officer Diaz searched the vehicle') — it's clearer about who did what.
- Quotation marks for exact words
- Use them around what a person actually said: He stated, 'I did not see the stop sign.'
- Goal of a police report
- To record an incident clearly, accurately, and completely so anyone can understand what happened.
- Best report answer on the test
- Usually the choice that includes ALL the required facts in plain, clear language.
- Order events in a report
- Chronologically — in the order they actually happened.
- Fact vs. conclusion in a report
- Record observable, attributable facts; leave out the officer's interpretation or opinion.
- First person vs. third person
- Many agencies use first person ('I observed…'); be consistent with whatever style is required.
- Should a report include speculation?
- No — only what was observed, reported, or established by fact; never guess at motive or intent.
- Why be specific about time and place?
- 'March 3 at 8:45 p.m. at 210 Birch Lane' is usable; 'last night somewhere downtown' is not.
- Complete sentence in a report
- Must have a subject and a verb and express a full thought: 'The driver fled north at midnight.'
- Quoting a suspect or witness
- Use their exact words in quotation marks when wording matters: He said, 'I did not see the stop sign.'
- Reporting Party field
- Identifies the person who reported the incident (e.g., Kevin Tran).
- Recording a description
- List concrete, observable details: 'a tall man in a red jacket,' not 'a suspicious-looking man.'
- Accuracy in a report — why it matters

- Proofreading a report
- Re-read for missing facts, unclear wording, and spelling/grammar before you submit.
- Recording observed vs. reported
- Distinguish what you saw yourself from what someone told you ('the victim stated…').
- Why avoid abbreviations/slang?
- They can be misread; clear, full wording prevents confusion in a legal record.
- Choosing the most complete answer
- On report-writing items, prefer the version that records all key facts and omits opinion.
- Time of call vs. time of arrival
- Different fields: when the call came in vs. when the officer reached the scene.
- Consistency in a report
- Keep names, times, and details consistent throughout the document.
- What does NOT belong in a report?

- Reading a chart or table in a question
- Read the title, headers, and units before pulling a value.
- Predicting the answer before reading choices
- Forming an expected answer first guards against tempting wrong options.
