Prison Officer Recruitment Process 2026: Every Stage

In shortOne national system, with each prison advertising its own vacancies: six published stages, 6 to 7 months on average, and merit or pass lists that last 12 months.

HMPPS recruits prison officers through a single national system. The process starts when you apply online and ends with a call from the recruitment team agreeing your training dates. Between those points sit three online assessments, a security and health vetting process, and a separate medical and fitness appointment.

That average hides a wide range. Some candidates move quickly because their checks are simple and a vacancy is open; others wait months for a post at their chosen prison, or for vetting clearance.

This page is the stage-by-stage guide. For the big picture, start with how to become a prison officer, then use our recruitment timeline planner to turn the stages into dates. If you only want to know how long it takes, see how long prison officer recruitment takes.

In shortTen minutes online, with three decisions that matter: OSG fallback, reasonable adjustments and which prisons to apply to.

The first step is to find a vacancy on prisonandprobationjobs.gov.uk or the Ministry of Justice jobs site, or to register interest if none is open. HMPPS says the application takes about ten minutes. You provide your National Insurance number, personal details and answers to eligibility questions about age, right to work and nationality.

If you have already read our requirements guide, you should know the answers before you start.

1. OSG fallback

Whether to tick the box to be considered for Operational Support Grade (OSG) alongside the officer role. HMPPS says the assessment centre also tests suitability for OSG, so ticking it gives you a fallback if you do not meet the officer bar.

2. Reasonable adjustments

If you tick 'yes', HMPPS contacts you to agree changes before any test or interview, such as extra time, someone reading questions aloud or transcribing answers, written interview questions with notice, or flexible time slots. HMPPS says you will not be penalised for applying.

3. Which prisons

You can apply to several and your first application's scores are reused.

In shortA 25 to 40 minute online test of basic numeracy and officer behaviours that you must pass; the scoring key is not published.

The scenario-based test (SBT) is an online assessment taking 25 to 40 minutes. HMPPS describes it as testing basic numeracy skills and the behaviours expected of a prison officer. A practice test is available on the careers site and you should take it more than once.

Scenario tests of this kind typically present a work situation and ask you to judge which responses are most and least effective. HMPPS does not publish the scoring key or the pass mark.

The numeracy element is described as basic, so if arithmetic is a weak spot, practise percentages, time and simple tables rather than advanced maths.

In shortA short, untimed self-description of up to 20 minutes where consistency counts; there are no published answers or pass mark.

The values-based assessment (VBA) takes up to 20 minutes and has no time limit. It explores your alignment with HMPPS core values. There are no published answers and no published pass mark.

• Managing a quality service
• Making effective decisions
• Caring (named as the technical area)

In shortAbout 2.5 hours online with an interview, role-play and written test, replacing the old in-person ARC; results are due within three working days.

The online assessment centre (OAC) replaces the old in-person assessment and recruitment centre. The old 'ARC' name still circulates on forums and older websites, and some of what they describe (actors, in-person rooms) is outdated.

Expect the interview to explore your motivation, your values and examples of how you have behaved in difficult situations. The role-play will test how you communicate and de-escalate under pressure. The written test assesses how clearly and sensibly you set out information.

HMPPS does not publish the questions or the marking scheme, so be cautious about any source offering 'real' questions. Our assessment centre guide and interview questions guide set out how to prepare without claiming insider knowledge.

In shortChecks take 8 to 10 weeks and start only after the assessment centre; the policy publishes no debt threshold, so declare anything relevant and ask.

After the assessment centre and once a vacancy is available, pre-employment checks begin. HMPPS quotes 8 to 10 weeks and says they cover security, identity, employment history and health screening. The vetting policy (PSI 07/2014, revised 20 February 2025) sets Enhanced Check Level 2 as the minimum for directly employed prison officers, which includes:

• Identity, proof of address, nationality and right to work
• A criminal record check including spent and unspent convictions (subject to filtering)
• Employment references and a personal counter-signatory reference
• A check against the HMPPS Exclusion List
• A signed declaration of not belonging to racist groups

In shortA separate appointment at a designated centre covering health checks and a bleep test, shield and grip assessment; third-party standards are reported, not official.

The medical and fitness assessment is a separate appointment with a trained occupational health professional at a designated centre. HMPPS lists Swindon, Cambridge, South London (Croydon), Rugby (Newbold Revel), Leeds and Manchester. Travel expenses of up to £100 are available for UK travel.

• Eye test
• Hearing test
• Blood pressure check and basic health screening
• Bleep test (a shuttle run between two points)
• Upper-body strength assessment using a 7 kg riot shield and a grip test

In shortAfter clearance the team calls to agree an offer and dates; how fast you are reached depends on whether the vacancy is pass or merit.

After medical and fitness clearance the recruitment team calls to agree a final offer, start date and training dates. The Pay Review Body's report describes the fitness test as falling between the provisional and final offer, which fits this order.

You are then on the first step of the pay scale (see our starting salary guide) and begin the induction and foundation training described in our POELT training guide.

In shortOnly the six-month wait after failing the assessment centre is confirmed by a current document; the other periods are dated or unpublished.

The only reapplication period confirmed by a current document is the six-month ban after failing the assessment centre, which is stated in the October 2026 HMP Birmingham advert.

A 2018 HMPPS blog said the wait was at least two months for the online test and 12 months after failing pre-employment or security vetting, but these are dated and may have changed, so we describe them as historic.

Separately, the vetting policy confirms that non-disclosure of offences is likely to lead to refusal with no leave to reapply for 12 months.

In shortApply widely if you are flexible on location, because scores are reused and merit lists rank you by score for 12 months.

Two details of the system change how you should plan. First, vacancies are advertised per prison, and you can apply to more than one. Your assessment scores from the first application are reused, so a second or third application takes little extra effort.

If you are flexible on location, apply widely: some prisons receive far more applicants than posts, and others struggle to fill vacancies, which is partly why market supplements exist at specific prisons.
