How long is the probation period? What the documents say

In shortThe only official document we found gives two lengths, 12 months and 6 months, so plan for 12 and ask HR to confirm which applies to you.

The only official document we found that states a length for new prison officers is the Band 3 Prison Officer job description JD048 'Safe, Decent and Secure', version 8.0, issued on 26 February 2020.

HMPPS attaches it to current vacancies, including the HMP Birmingham advert published on 27 August 2026 and closing on 15 October 2026.

The two quoted statements below cannot both describe the same people in the same way. One reading is that 12 months is the older, post-POELT period and the six-month line is a Civil Service-wide rule for external joiners that was added later. That is our interpretation, not an HMPPS explanation.

The sensible reading for a candidate is to plan for 12 months and ask your recruitment team to confirm in your offer or contract which length and which start date applies to you.

Our POELT guide and week by week guide give the training stages that come first, and our first year guide places probation within the year.

Under technical requirements
'Following completion of the POELT course you will be subject to a 12 month probationary period.'
Under minimum eligibility, same page
'All external candidates are subject to 6 months' probation. Internal candidates are subject to probation if they have not already served a probationary period within HMPPS.'
2018 HMPPS blog and youth justice pages
The blog also said 12 months and said the clock starts one week before POELT at your home prison. HMPPS's youth justice worker pages refer to a 12-month probationary period.
Search summaries
A search summary we saw suggested external recruits serve six months; we could not confirm it from a primary page. The careers page itself confirms only that you must complete the probationary period at Band 3 before applying to Band 4.

Documents opened or read in full on 3 October 2026. The JD also contains figures that have moved on, such as a 17% unsocial hours payment (the August 2026 advert quotes 20%) and a custodial care NVQ 3 requirement, so treat it as dated in places.

Failing POELT: what is published and what is not

In shortThe consequence of failing is stated plainly, but the process (pass mark, retakes, appeal) is not published and there is no official pass rate.

The strongest published statement is in the same job description, quoted below.

That wording is explicit about the consequence, but it sets no number of attempts, no pass mark and no appeal route.

Anyone who quotes a pass rate for POELT is not citing an official source: HMPPS does not publish one. Plenty of people pass, and the sources suggest support is available, for example from coaches and mentors, but we cannot give you figures.

Our site's earlier statement that 'the pass rate is high' has been removed for exactly this reason.

The job description's wording
'If successful in your application, your continuation in this role is dependent on passing all modules within the initial Prison Officer Entry Level Training (POELT), which is a pathway to becoming a fully competent Prison Officer. Failure to successfully complete and pass POELT course could result in your removal from this role and may result in the termination of your employment.'
  • HMPPS's careers page says you are assessed continuously during the foundation course on all aspects of the role.
  • The Use of Force Policy Framework says all new Band 3 officers are assessed against competence criteria at the end of initial training and issued with a logbook certifying competence.
  • It also says untrained or uncertified staff must not be involved in planned control and restraint; we cover that in our control and restraint guide.
  • There is no published rule on retaking a module, repeating a week, deferring to another cohort or on what happens if illness or injury interrupts training.

If you are worried, ask in writing

  • How does reassessment work, and can I retake modules?
  • Who decides, and how can decisions be challenged?

A published example: how the Scottish Prison Service runs probation

In shortEngland and Wales publish no equivalent, so the SPS 2017 policy (dated, a different employer) is a template for questions, not the rules you will face.

Because England and Wales do not publish an equivalent, it helps to see what a published prison-service probation policy looks like.

The Scottish Prison Service's Probationary Policy HR048/v001 was published on 15 November 2017 with a review date of 2020, so it is dated, and SPS is a separate employer with its own pay and terms.

Treat it as a template, not as the rules you will face. It sets a probationary period of one year for all new employees, forming part of the contract of employment, with the aim of letting SPS assess objectively whether the employee is suitable.

The SPS review structure

  1. Months 1, 4, 8 and 10Four structured review meetings

    Held by the line manager, in addition to normal supervision.

  2. First two monthsOfficer Foundation Programme reports

    People attending the programme have separate progress reports.

  3. At the endOne of three outcomes

    The appointment is confirmed, in exceptional circumstances the period is extended for a fixed time, or employment is terminated.

Source: Scottish Prison Service Probationary Policy HR048/v001, published 15 November 2017. It applies to SPS employees only.

Extensions, hearings and appeals

  • Extensions are considered only where performance is likely to improve with extra time or where absence has prevented a fair assessment, and normally last no more than six months.
  • If difficulties arise, a Probationary Hearing is arranged with at least five working days' notice.
  • You may be accompanied by a union representative or a colleague, with an HR representative present.
  • A dismissal can be appealed to the Governor, whose decision is final.

What else the policy covers

The policy also covers pay (increases are subject to satisfactory performance during the probationary period), attendance (not all attendance provisions apply, and absence is closely monitored), reasonable adjustments, maternity and parenting, and control and restraint competence.

Operational probationers should normally have achieved Phase 1 competence before returning to their establishment, with a recovery plan if not, and competence evidenced annually. We do not know whether HMPPS runs anything like this for England and Wales prison officers, but it shows the kinds of questions you can ask your own HR team.

What reviewers are likely to look at

In shortThere is no published England and Wales checklist, so this is our reading of the role documents: observable duties, four behaviours and compliance.

There is no published England and Wales checklist, so this section is our reading of the published role documents, not an HMPPS statement. The job description lists the duties of the post, and those are the things a line manager can observe, so they are the realistic basis for judging whether you are performing.

The four behaviours in the person specification are communicating and influencing, managing a quality service, making effective decisions and caring or working together. They are assessed in recruitment, and they are a sensible way to think about what a probation conversation covers.

  • Supervising prisoner activities including exercise and association, and making sure meals are served.
  • Locking prisoners in, keeping the unit roll and unlocking in good time.
  • Supporting vulnerable prisoners and passing on concerns; dealing with self-harm in line with prevention strategies.
  • Completing reports and behaviour entries, and receiving applications and complaints.
  • Searching and carrying out fabric checks, and acting as first on scene for incidents.

A monthly self-check

  • Are you completing statements and records on time?
  • Are you using the radio and keys correctly and securely?
  • Are you challenging rule breaking calmly and consistently?
  • Are you asking for help when you do not know?

The compliance elements

On top of those sit competence certification in use of force, completion of ACCT training and local induction, timely reporting, attendance, conduct and adherence to vetting conditions.

That includes reporting changes of circumstances such as new partners, housemates or relatives sharing the home, which the HMPPS vetting policy requires.

In shortDay-one rights apply now; ordinary unfair dismissal protection is intended to arrive after six months from 1 January 2027, but how it applies to your terms is a matter for HR, your union or an adviser.

Probation periods are not a legal concept in themselves. Acas says there is no legal requirement for probation periods and they can be any length, and that 'day one' employment rights apply during them. Employees can resign during probation with the minimum statutory notice or the notice in their contract.

  • Minimum wage and paid holiday.
  • Protection from discrimination.
  • Whistleblowing protection.
  • Trade union membership rights.

If something goes wrong

The unfair dismissal change

The Employment Rights Act 2025 will reduce the qualifying period for protection against ordinary unfair dismissal from two years to six months.

The Government's factsheet says it intends to bring this into force on 1 January 2027, extending protection immediately to employees who already have six months' service and to others as they reach it, and to remove the cap on compensatory awards for ordinary unfair dismissal.

It also says the Act does not change the existing day-one protections against discrimination and automatically unfair grounds for dismissal. In practice, someone starting a prison officer role in 2027 will gain unfair dismissal rights part-way through a 12-month probation, while someone dismissed before then may have only the day-one protections.

Why probation matters for pay, promotion and retention

In shortPassing probation unlocks Band 4 and specialist routes; how it interacts with Band 3 pay points is not published.

  • Band 3 to 5 officers with under 3 years' service30.2%At 30 June 2026
  • Largest leaver group0 to 1 years' servicePay Review Body, year to September 2025
  • 2026/27 progression1 pay pointBands 3 and 5, in post on 31 March 2026 and not on formal poor performance procedures

Passing probation unlocks progression. HMPPS's career page says that after completing the probationary period at Band 3, officers gain access to varied placements, including specialist wings, and can apply for Band 4 as a supervising officer or prison officer specialist.

Specialisms include suicide prevention, control and restraint, first aid, hostage negotiation or drug testing; a custodial manager accreditation allows a move from Band 3 directly to Band 5. Our guides to the supervising officer role and promotion explain the steps, and the free promotion calculator models the pay.

Pay progression and retention

Pay progression within Band 3 is a separate question.

For 2026/27 the Pay Review Body's award gave Band 3 and Band 5 staff one pay point of progression from 1 April 2026 if they were in post on 31 March 2026 and not on formal poor performance procedures, which shows that performance procedures can affect progression.

We do not know how probation interacts with pay points for new joiners, and we could not find a published rule. Our pay progression guide tracks what is published.

The retention picture explains why HMPPS cares about the first year. Probation is both a test and a support structure at that high-risk stage. Our staffing and attrition guide has the figures.

Questions to ask HR before you start

In shortBecause so little is published, ask for the answers in writing and keep the replies.

Keep the replies. If anything changes later, a dated email is much more useful than a recollection. If you are still applying, use the free recruitment timeline planner to see where probation would fall, and the Candidate Bundle for the preparation tools.

The basics

Ask

  • How long is my probation?
  • When does it start: the first day, the end of POELT or a week before?
  • Is it 12 months or 6, and why?
  • What does my contract say?

Process

Ask

  • How many reviews, and who conducts them?
  • What is the standard, and how are concerns raised?
  • Can the period be extended, and for how long?
  • Can I be accompanied, and is there an appeal?

Training, competence and adjustments

Ask

  • What happens if I do not pass a module first time, can I retake, and what support is there?
  • How are use of force and ACCT competence recorded, and what happens if illness or an injury interrupts training?
  • If I have a disability or health condition, who do I speak to, and how are adjustments recorded and reviewed during probation?
  • How is absence treated during probation, and how does it interact with probation length and pay progression, since the Scottish policy treats absence specially?

Frequently asked questions

How long is a prison officer's probation period?

The Band 3 job description attached to HMPPS adverts says 12 months following completion of POELT, and in another line says external candidates are subject to 6 months. A 2018 HMPPS blog said 12 months. Because the documents conflict, ask HR to confirm the length and start date in writing.

Can you be sacked for failing POELT?

The job description says continuation in the role is dependent on passing all POELT modules and that failure could result in removal from the role and may result in termination of employment. Pass marks, retake rules and appeals are not published. Ask your line manager and the training team for the process in writing.

Does the probation period start before or after training?

Sources differ. The job description says the 12-month period follows completion of POELT. A 2018 HMPPS blog said the clock starts a week before training at your home prison. Current HMPPS pages do not settle it, so ask your recruitment team which applies to you.

Do I have unfair dismissal rights during probation?

Day-one protections such as discrimination and whistleblowing already apply. Ordinary unfair dismissal needs two years' service now; the Government intends to reduce that to six months from 1 January 2027. How the rules apply to your terms is a matter for HR, your union or an adviser.

What happens at the end of probation?

HMPPS does not publish the England and Wales process. Under the Scottish Prison Service's 2017 policy, the outcome is confirmation, a fixed extension or termination. The HMPPS career page says you must complete the Band 3 probationary period before applying for Band 4, so confirmation matters for progression.

Can I be accompanied at a probation meeting?

The SPS policy gives a right to be accompanied by a union representative or colleague at hearings. For England and Wales, HMPPS has not published an equivalent for probation reviews. Ask in writing, and contact the POA if you are a member. Our guide to the right to be accompanied explains the wider rules.

Does sick leave extend probation?

We could not find a published England and Wales rule. In the SPS policy, an extension can be considered where attendance has prevented a fair assessment of performance, normally for no more than six months. Ask HR how absence is treated in your probation, and raise any health condition or disability for reasonable adjustments.

Is probation different for ex-military recruits or other schemes?

HMPPS says Advance into Justice offers a two-year fixed-term contract that can become permanent after a year, and some schemes have special terms. The job description says internal candidates serve probation only if they have not already served one in HMPPS. Ask the scheme team how probation applies to you.
