Situational Judgement and Decision-Making in a Custodial Setting
Situational judgement questions test whether you can rank or choose responses in the way a competent, newly qualified prison officer should. The concepts you must hold in mind are: duty of care (the prison's responsibility for the safety and wellbeing of everyone in custody), proportionality (the least intrusive action that resolves the issue), the security hierarchy (life, safety, security, then routine), escalation and referral (knowing what you must report and to whom), and record-keeping (decisions must be defensible and written up).
A reliable rule of thumb is the SAFE scan: Safety first (is anyone at immediate risk?), Authority (what am I authorised to do, and who else needs to know?), Fairness and consistency (would I treat every prisoner this way?), Evidence (what must be recorded and passed on?).
Common traps: choosing the most decisive or punitive option rather than the correct one; acting alone when the policy expects you to inform a supervisor; ignoring the informal route (a quiet word) when it would resolve the matter; and forgetting to record. Questions often ask you to rank responses from most to least appropriate - the 'most appropriate' is usually the one that is safe, proportionate, within your role, and properly reported.
Worked example. A prisoner refuses to return to his cell, saying he is scared of his cellmate. Ranking: (1) keep him in a supervised area and call your supervisor while gathering information - safe, immediate, within role; (2) separate the men and log the concern; (3) tell him he must comply or face adjudication - escalates without addressing the risk; (4) ignore it as attention-seeking - breaches duty of care. Option 1 wins because it protects safety, uses the chain of command, and creates a record.
