Situational Judgement and Decision-Making in a Custodial Setting

  • Prioritise safety of life first, then security of the establishment, then welfare and rehabilitation needs.

  • Use the graded response principle: least restrictive intervention that resolves the risk is preferred.

  • Record decisions contemporaneously; an undocumented decision carries little evidential weight.

  • Escalate when an incident exceeds your authority, competence, or available resources - do not improvise alone.

  • Separate the person from the behaviour when judging: assess risk and need, not likeability.

  • Test a decision against four checks: lawful, proportionate, necessary, and defensible on the record.

  • Time-critical incidents: secure the area, count and account for prisoners, then inform the duty governor.

  • Where rules and welfare conflict, apply the rule but report the welfare concern through the proper channel.

Numerical Reasoning and Data Interpretation

  • Percentage change = (new − old) ÷ old × 100; a fall from 80 to 60 is a 25% decrease, not 20%.

  • Percentage points measure the difference between two percentages; percent measures relative change.

  • Rate per 1,000 prisoners = (events ÷ population) × 1,000 - always state the denominator.

  • Average (mean) = total ÷ count; the median is the middle value and resists extreme outliers.

  • Ratio scaling: if staff:prisoners is 1:6 at 120 prisoners, staff = 120 ÷ 6 = 20.

  • To compare mixed groups, convert to a common base (per 100 or per 1,000) before ranking.

  • Rounding early compounds error; carry full precision and round only the final answer.

  • Check plausibility: a percentage above 100% or a rate far outside the range signals a denominator error.

Written and Verbal Communication

  • A custodial report follows: who, what, when, where, what action was taken, what remains outstanding.

  • Use plain English and active voice; avoid jargon, acronyms, and value judgements about character.

  • Distinguish fact from opinion explicitly; attribute hearsay to its source rather than asserting it.

  • Radio protocol: identify yourself, state location, state the situation, request the resource, acknowledge.

  • In verbal handover, use a structured repeat-back to confirm the receiver has understood.

  • Write statements in chronological order, in the first person, and never alter a signed statement afterwards.

  • Neutral wording matters: 'raised his voice' is observable; 'was aggressive' is an interpretation.

  • Confidential information is shared only on a need-to-know basis and marked accordingly.

Managing Challenging Behaviour and Conflict De-escalation

  • De-escalation sequence: calm verbal engagement, reduce audience and stimuli, offer choices, allow time, then physical intervention only if necessary.

  • Behaviour is often communication of an unmet need - identify the trigger (fear, loss, pain, boredom) before responding.

  • Maintain distance, keep hands visible, avoid cornering, and never turn your back on an agitated person.

  • Lower your voice and slow your speech; matching escalating volume reinforces the escalation.

  • Offer limited, genuine choices to restore a sense of control without conceding the rule.

  • Use a team approach: one officer speaks, others secure the area and manage the audience.

  • Physical restraint must be necessary, proportionate, lawful, and of minimum duration, with continuous monitoring.

  • After any incident, debrief and record; unresolved triggers predict repeat incidents.

Teamwork, Integrity and Professional Values

  • Integrity means doing the right thing when unobserved; reporting a colleague's misconduct is a duty, not disloyalty.

  • Accept gifts, favours, or relationships with prisoners or their families only as expressly permitted; undeclared contact is a disciplinary matter.

  • Declare conflicts of interest immediately, including knowing a prisoner or their associates.

  • Follow the chain of command for decisions, but a lawful order that is clearly unsafe should be challenged and reported.

  • Confidentiality: prison information is shared on a need-to-know basis; discussing it outside work is a breach.

  • Reliability covers punctuality, accurate recording, and completing handover tasks before leaving.

  • Support colleagues without covering up errors; a cover-up converts a mistake into misconduct.

  • Boundaries: familiarity with prisoners undermines authority and creates security and safeguarding risks.

Diversity, Equality and Safeguarding

  • The Equality Act 2010 protects nine characteristics, including age, disability, race, religion, sex, and sexual orientation.

  • Direct discrimination treats someone less favourably because of a protected characteristic; indirect discrimination applies a neutral rule that disadvantages a group.

  • Reasonable adjustments are a legal duty for disabled prisoners and staff, not a favour.

  • Protected characteristics must never determine treatment; individual risk assessment does.

  • Safeguarding indicators include self-harm, unexplained injuries, withdrawal, and fear of a particular prisoner.

  • Vulnerable prisoners (young adults, those with mental illness, learning disability, or prior victimisation) require referral, not just observation.

  • Record and report all safeguarding concerns immediately; do not investigate yourself.

  • Hate incidents are recorded even where no criminal offence is established, so patterns can be identified.

Awareness of the Prison Officer Role, Rules and Security Responsibilities

  • Core duties: keep prisoners safe and secure, maintain order, support rehabilitation, and protect the public.

  • Security has three layers: physical (fabric, locks), procedural (searches, counts, key control), and dynamic (relationships and observation).

  • Counts and roll checks must be accurate and reported immediately; a discrepancy is a security incident.

  • Key control: keys are signed for, carried personally, never passed to a prisoner, and reported at once if lost.

  • Searching follows policy and is lawful only with proper authority and respect for dignity.

  • Contraband categories include weapons, drugs, mobile phones, SIM cards, and unauthorised money.

  • Report intelligence and observations promptly; small fragments combine into actionable intelligence.

  • Prohibited relationships and unauthorised information disclosure are among the most serious breaches of the role.
