Prison officer application tips: stage-by-stage advice (2026)

In shortHMPPS publishes the stages, rough timings and behaviours but not scoring or pass marks, so no tip can promise a result.

Most advice online is anecdotal. Our approach is to base tips on the published process and flag where advice is our own judgement. A tip that sounds like insider knowledge about scoring should make you suspicious.

Because pass marks are unpublished, the right way to prepare is to cover the behaviours and requirements well and be careful about the things in your control: accuracy, honesty, timing, technology and fitness.

In shortThe form takes about 10 minutes; ask for reasonable adjustments here and declare your history accurately.

You search vacancies or register interest, give your National Insurance number, answer eligibility questions and provide personal details. You can tick to be considered for Operational Support Grade at the same time, and you can apply to several prisons, with your first application scores reused.

If you need reasonable adjustments, ask for them here. The HMPPS page says you tick 'yes' on the form and are then contacted to agree adjustments before any test, interview or assessment, and you will not be penalised for applying.

In shortBoth are online and unscored in public, so prepare your setup and think through the listed behaviours.

The scenario-based test is online, takes 25 to 40 minutes, tests basic numeracy and the behaviours expected of a prison officer, and has a practice test. You must pass it.

The values-based assessment asks about HMPPS core values and runs up to 20 minutes with no time limit. It sits within the behaviours HMPPS lists: communicating and influencing, managing a quality service and making effective decisions, with Caring as the technical area.

In shortThe main competitive stage: set up your tech first, then prepare six to eight true examples.

The online assessment centre takes about 2 hours 30 minutes on a laptop with a webcam, and includes an interview, a role-play scenario and a written test. Results are due within three working days. Women's prisons add three behaviour-based written questions.

For merit vacancies, the scores decide your position on the list.

• Charged laptop and tested webcam and microphone
• A quiet and neutral background
• A back-up connection if you have one
• Any reasonable adjustments confirmed in advance

1. Choose six to eight real experiences that match the listed behaviours.
2. Write each as situation, responsibility, action, result and learning, in your own words.
3. Practise saying them aloud, timing each to about two minutes.
4. Test your laptop, webcam, microphone and connection on a quiet day.
5. Have your adjustments confirmed and your documents ready.
6. Rest before the day and arrive early to the online room.

In shortWrite your own truthful answers and declare everything: AI-generated content presented as yours may lead to withdrawal.

The October 2026 HMP Birmingham advert states that all examples and statements must be truthful, factually accurate and taken directly from your own experience. Where plagiarism has been identified, including presenting ideas or experiences generated by artificial intelligence as your own, applications may be withdrawn.

Using an AI tool to polish grammar is a different matter from having it write your examples, but the line is for the assessor, not you, so the safest course is to write your own answers.

In shortChecks take 8 to 10 weeks, so prepare documents early and start fitness work as soon as you apply.

Pre-employment checks begin only after an assessment centre pass and a vacancy. They include identity, address history, employment history, references and the criminal record check, with Enhanced Level 2 vetting as a minimum and the Counter-Terrorism Check at high security prisons.

Prepare documents before you are asked: identity, proof of address, three years of employment history and referee details. For high security vetting the security questionnaire has a 15 working day deadline, after which the application is closed.

Medical

Carried out by an occupational health professional and includes eye, hearing and blood pressure tests, at sites including Swindon, Cambridge, Croydon, Rugby, Leeds and Manchester, with travel expenses up to £100 in the UK. Declare health conditions honestly; the careers pages say a physical or mental health issue will not necessarily prevent you.

Fitness test

A bleep test and an upper-body test with a 7 kg riot shield and grip equipment. Official thresholds are not published and third-party reported numbers are unconfirmed, so see our fitness test guide and training plan.

In shortMost mistakes are avoidable; you cannot control the result, but you can control the preparation.

None of this guarantees success, and HMPPS publishes no officer-specific pass rate. But you can control the preparation, and the stages are fair game for it.
