Observe behavior in context: look for clusters of cues such as posture, breathing, hand placement, and speech pace rather than isolating one gesture.

Use a de-escalation sequence: stabilize distance and cover, lower voice and slow speech, ask open-ended questions, acknowledge concerns, offer limited choices, and act if threats persist.

Open-ended questions such as 'What happened?' gather narrative; closed questions such as 'Did he hit you?' confirm specific facts.

Active listening includes paraphrasing content, reflecting emotion, summarizing, and asking clarifying questions before responding.

Procedural justice commonly includes four elements: giving voice, neutrality in decision-making, respectful treatment, and trustworthy motives.

Force decisions are evaluated by reasonableness, necessity, and proportionality; the response level should decrease as resistance decreases.

Document observable actions and quoted statements separately from opinions, assumptions, or conclusions.

Bias check: compare an initial impression with specific observed facts and consider alternative explanations before acting.

Main idea is the central point of a passage; supporting details explain, illustrate, or prove that point.

Explicit information is stated directly in the text; an inference is logically supported by the text but not directly stated.

Common author's purposes include informing, explaining, persuading, entertaining, and describing.

Tone is inferred from word choice, connotation, and emphasis rather than from the topic alone.

Common text structures include chronological order, cause-effect, compare-contrast, problem-solution, and description.

Signal words guide structure: 'however' signals contrast, 'therefore' signals conclusion, 'because' signals cause, and 'first/then' signals sequence.

Context clues include definition, example, synonym, antonym, and restatement clues.

Answer choices using absolutes such as 'always' or 'never,' or ideas outside the passage's scope, are usually unsupported.

Subject-verb agreement: a singular subject takes a singular verb, and prepositional phrases between subject and verb do not change agreement.

Compound subjects joined by 'and' take plural verbs; subjects joined by 'or' or 'nor' agree with the nearer subject.

A pronoun must agree with its antecedent in number and gender and must have a clear, unambiguous referent.

Two independent clauses cannot be joined by only a comma; use a period, semicolon, or comma plus coordinating conjunction.

A complete sentence requires a subject, a finite verb, and a complete thought.

Commas set off nonessential clauses, introductory elements, and items in a series.

Apostrophes show possession or omission, as in 'officer's report' or 'don't,' not simple pluralization.

Keep verb tense consistent unless a time shift is clearly signaled by the sentence.

Parallel structure requires items in a list or comparison to use the same grammatical form.

Order of operations: parentheses, exponents, multiplication and division left to right, then addition and subtraction left to right.

Percent of a number equals the decimal equivalent multiplied by the number; percent change equals (new minus old) divided by old, multiplied by 100.

Mean equals the sum of values divided by the number of values; median is the middle value when ordered; mode is the most frequent value.

A ratio compares quantities; a proportion states two equal ratios and is solved by cross-multiplication.

Distance equals rate multiplied by time, or d = rt; rate equals distance divided by time; time equals distance divided by rate.

Rectangle area equals length times width; triangle area equals one-half times base times height; circle circumference equals 2 times pi times radius.

Unit conversion uses a conversion fraction equal to 1 so unwanted units cancel.

Probability equals favorable outcomes divided by total equally likely outcomes and ranges from 0 to 1.

Rounding: identify the place value, then look at the digit to its right; 5 or greater rounds up.
