Chain of custody

The documented, unbroken record of who handled an item of evidence, when, and for what purpose, from seizure through final disposition. Gaps or missing signatures can make evidence unusable in disciplinary or criminal proceedings.

Related: Contraband, Incident report
Contraband

Any item an inmate is not authorized to possess, including weapons, drugs, cell phones, tattoo equipment, and excess or altered property. Finding and documenting contraband is a core search responsibility.

Related: Shakedown, Chain of custody
Shakedown

A planned, systematic search of a cell, housing unit, or entire facility for contraband. Officers announce and document shakedowns, work in teams, and secure the area before searching.

Related: Contraband, Pat-down search
Pat-down search

A hands-on search of a person's outer clothing for weapons or contraband, conducted with a same-sex officer present and following a consistent, documented pattern. It is less invasive than a strip search and requires less justification.

Related: Shakedown, Use of force
Use of force continuum

A graduated framework ranking officer responses from presence and verbal direction up to deadly force, matched to the level of resistance faced. Officers must be able to justify each escalation and de-escalation step.

Related: De-escalation, Duty to intervene
De-escalation

Techniques such as calm speech, active listening, creating space, and offering choices that reduce tension before force becomes necessary. Most confrontations can be resolved without physical intervention when time and tactics allow.

Related: Use of force continuum, Active listening
Duty to intervene

The obligation of an officer to step in and stop another officer's excessive or unlawful force, and to report it. Failure to intervene can result in discipline and criminal liability for the observing officer.

Related: Use of force continuum, Code of conduct
Inmate count

The formal tally of inmates at specified times, verified against a roster and reported to control. An inaccurate count, or a count that does not clear, triggers a lockdown and full recount.

Related: Roster, Headcount discrepancy
Headcount discrepancy

A mismatch between the number of inmates physically present and the number recorded on the roster. Officers must immediately stop movement, secure the area, and report to the control center for a recount.

Related: Inmate count, Roster
Roster

The official list of inmates assigned to a housing unit, including identifying data and bed assignments. Officers verify the roster against the physical presence of inmates during counts and movement.

Related: Inmate count, Headcount discrepancy
Incident report

A factual written account of an unusual event, written in chronological order, first person, and past tense. It records who, what, when, where, how, and what action was taken, without opinion or speculation.

Related: Objective writing, Chain of custody
Objective writing

Reporting only observable facts and direct quotations rather than conclusions, labels, or assumptions. Instead of writing that an inmate was angry, describe the clenched fists, raised voice, and specific words used.

Related: Incident report, Active listening
Chronological order

Arranging events in the sequence they occurred, with times noted when known. It is the standard structure for incident reports because it lets a reader follow exactly what happened and when.

Related: Incident report, Objective writing
Active voice

A sentence structure in which the subject performs the action, as in 'Officer Reyes secured the door.' Reports favor active voice because it clearly identifies who did what.

Related: Passive voice, Incident report
Passive voice

A sentence structure in which the subject receives the action, as in 'The door was secured.' It can hide who acted, so reports use it sparingly and only when the actor is unknown or irrelevant.

Related: Active voice
Subject-verb agreement

The rule that a verb must match its subject in number, as in 'The officer was present' versus 'The officers were present.' Errors are common when phrases separate the subject from the verb.

Related: Active voice
Pronoun reference

The clarity of the relationship between a pronoun such as he, she, it, or they and the noun it replaces. Ambiguous reference confuses reports, especially when several people are named.

Related: Objective writing
Main idea

The central point a passage or directive conveys, which the supporting details explain or prove. Identifying it first helps a reader answer comprehension questions and summarize policy accurately.

Related: Inference, Context clue
Inference

A conclusion drawn from evidence in a text rather than stated directly. On the exam, the correct inference is the one best supported by the passage, not the one that merely seems plausible.

Related: Main idea, Context clue

Surrounding words or sentences that help a reader work out the meaning of an unfamiliar term. Definitions, examples, contrasts, and restatements in the same paragraph are common types.

Related: Main idea, Inference
Insubordination

A deliberate refusal to obey a lawful order from a supervisor, or open disrespect toward that authority. It is a serious disciplinary offense distinguished from a good-faith question or a misunderstanding.

Related: Chain of command, Code of conduct

Personal, overly friendly, or romantic interaction with an inmate that crosses professional boundaries. It is prohibited because it compromises security and can lead to manipulation or contraband introduction.

Related: Conflict of interest, Contraband

Related: De-escalation, Objective writing

The general direction in which data moves over successive periods, ignoring short-term fluctuation. Identifying a trend requires looking at several data points, not just two.

Related: Rate, Average
Observation

Deliberate, focused attention to people, places, and changes in a setting, using all the senses. Effective observation is systematic and repeated rather than casual or passive.
