Prison Officer (UK) key terms

The lawful application of physical control or restraints by staff when other methods have failed and there is a risk to safety. It must be necessary, proportionate and reported afterwards.

Techniques such as calm speech, active listening and adjusting the environment that reduce tension before a situation becomes violent. Staff should try these before resorting to physical intervention.

Approved physical techniques used by trained staff to hold or move a person safely during an incident. Only accredited methods may be used and each application is recorded and reviewed.

The principle that any response must be no more than necessary to deal with the risk. It balances the rights of the person against the need to protect others and maintain order.

A continuous, in-the-moment judgement of danger that staff make as circumstances change. It informs whether to intervene, withdraw, call for help or escalate a response.

The formal internal disciplinary process where an independent adjudicator or governor hears alleged breaches of prison rules and decides on a finding and any punishment.

The legal framework setting out how prisons are run, including offences against discipline, procedures for hearings and the rights and duties of prisoners and staff.

A written notice charging a prisoner with breaching discipline rules. It must be completed accurately and promptly so the prisoner knows the allegation and can prepare a response.

Removal of a prisoner from normal association for a set period, usually for safety or order reasons. It is reviewed regularly and subject to safeguards because it restricts normal contact.

An official written record of an event such as a fight, injury or use of force. It must be factual, timely and complete because it supports investigations, reviews and legal processes.

Recording facts and observable behaviour without opinion, emotion or speculation. It makes reports reliable evidence and avoids bias or assumptions about a person's motives.

Paying full attention, reflecting back what is said and checking understanding rather than interrupting. It builds trust, calms tension and helps staff gather accurate information.

Asking questions that invite explanation rather than a yes or no answer, such as 'what happened next?'. It gathers fuller information and encourages the other person to talk.

Showing that you understand another person's feelings without necessarily agreeing with their behaviour. It supports rapport and can reduce confrontation in stressful encounters.

The legal and ethical obligation to protect the health, safety and wellbeing of prisoners and colleagues. It applies even to people who have harmed others or are uncooperative.

Action taken to protect people at risk of harm, including self-harm, abuse, radicalisation or exploitation. Staff must recognise warning signs and report concerns through proper channels.

Assessment, Care in Custody and Teamwork: the structured plan used to support a prisoner at risk of suicide or self-harm. It involves monitoring, regular reviews and multi-disciplinary input.

Treating every person with fairness and respect, recognising that different people may need different adjustments to achieve the same opportunities and outcomes.

The range of differences among people, including ethnicity, religion, disability, sexuality, age and background. Recognising diversity helps staff avoid assumptions and treat people as individuals.

Making decisions based on evidence and rules rather than personal feelings, prejudice or favouritism. It is central to fairness and to maintaining trust in the prison system.

A practical change made to remove a disadvantage, such as adapting communication for a prisoner with a disability. It supports equal access to services and fair treatment.

Acting honestly and consistently with professional values, even when unobserved or under pressure. It includes refusing bribes, not covering up mistakes and reporting wrongdoing.

Raising a concern about wrongdoing, danger or malpractice through the correct channel. It is protected by law when done properly and helps protect staff and prisoners.

The limits that keep relationships with prisoners appropriate and safe, such as avoiding personal favours, gifts or sharing confidential information. Breaching them risks manipulation and misconduct.

A gradual process where a prisoner builds trust or familiarity with staff to gain influence, information or contraband. Staff must recognise early signs and maintain boundaries.

The measures that prevent escape, disorder, contraband and harm, including searching, counting, keys and intelligence. Every officer contributes to it through vigilance and following procedures.

Any item prisoners are not permitted to possess, such as drugs, weapons or mobile phones. Finding and removing it is a core security duty and must be recorded correctly.

The lawful examination of cells, clothing or people to find contraband or evidence. It must follow procedure, respect dignity and be conducted by appropriately trained staff.

The formal check that every prisoner is accounted for at set times. Accuracy is critical because a discrepancy could indicate escape, injury or a serious incident.

A record of information that may indicate risk or criminal activity, such as threats or drug supply. It is passed to the security team and handled confidentially.

Working cooperatively with colleagues across shifts and disciplines, sharing information and supporting each other. It improves safety and consistency in how prisoners are managed.

The structured exchange of information between shifts or staff about prisoners, incidents and risks. Clear handovers prevent gaps in care and security.

A short meeting where staff receive updates on risks, incidents and tasks before a shift or operation. It ensures everyone has the same information and knows their role.

The ability to interpret figures, percentages, ratios and tables to reach a sound conclusion. In a prison context it may involve staffing levels, incident rates or timings.

Reading and drawing meaning from charts, tables and statistics, including spotting trends and anomalies. It requires checking units and comparing like with like before concluding.

The size of an increase or decrease expressed as a share of the original value, calculated by dividing the change by the starting figure and multiplying by 100.

A single value representing a set of numbers, commonly the mean found by adding all values and dividing by how many there are. It helps compare groups or periods.

A comparison of two quantities showing how much of one there is relative to another, such as staff to prisoners. Ratios are simplified and used for planning and checking cover.
