Capability, conduct and attendance: three different processes

In shortCapability, conduct and attendance are three different processes with different safeguards, so ask which policy is being used and ask for it in writing.

The HMPPS conduct policy (PSI 06/2010, last public text the 2013 re-issue) tells managers to deal with some matters as performance or attendance issues instead of misconduct. It says the primary purpose of the process is to encourage improvement rather than impose a sanction.

The Government said on 9 July 2026 that the Conduct and Discipline and Grievance policies are being rewritten, so assume that the stage names and thresholds you hear locally may change.

Misconduct
Behaviour that breaks a rule or standard, such as lateness without reason, disobeying a lawful instruction or a breach of security procedure.
Capability
Being unable to do the job to the required standard despite genuine effort, because of lack of skill, knowledge or aptitude.
Attendance or ill-health capability
Being unable to attend work or perform because of health. It has its own rules, explained in our guide to sickness absence management for prison officers.

Why the classification matters

Conduct allegation

  • Can lead to a formal investigation, suspension and even placement on the Exclusions Register if it is serious.

Poor performance matter

  • Handled through targets, support and review.
  • The HMPPS exclusion framework states that poor performance alone is not a reason to exclude.

What the published policy tells us, and what it does not

In shortPSI 12/2013 exists but is not published, so its stages, targets and sanctions are unknown to us; dismissals for poor performance are very rare in the statistics.

The gov.uk Prison Service Instructions index lists PSI 12/2013 NOMS Policy on Managing Poor Performance as extant but not published. Staff access is through the intranet and HR. We have not seen the text and will not describe its stages, targets, warning periods or sanctions, because any number we offered would be invented.

What can be said is derived from general law, the Acas Code, and the HMPPS conduct policy that points to it. A reasonable capability process in a large Civil Service employer typically has an informal stage and a formal stage.

Whether each of the steps below exists in the current HMPPS policy is something to confirm.

A typical capability process (to confirm against current HMPPS policy)

  1. Informal stageExplain, agree and support

    A manager explains the shortfall, agrees objectives and offers support, such as training, mentoring, a buddy, adjusted duties or an Occupational Health review.

  2. Formal stageStandard, evidence, review period

    The employer sets out the standard, the evidence of the shortfall, the support offered, a review period and the possible consequences, and can issue a formal warning.

  3. Final stageRedeployment, demotion or dismissal

    A final stage may consider these.

Spotting a fair process: what you should be given

In shortA fair capability process gives you a clear standard, the evidence, support, a real chance to improve and an appeal.

A capability process is more likely to be fair, and to survive a tribunal challenge, if you are given clarity and a real chance to improve. The Acas Code says that notification of a meeting should give sufficient information about the alleged poor performance and copies of any written evidence.

You have a right to be accompanied at a meeting that could result in a formal warning or other action. Employers should also investigate without unreasonable delay and give you the opportunity to put your case before any decision.

Five questions to ask

  • What exactly is the standard I am being measured against, and where is it written?
  • What evidence does the manager have, and can I see it?
  • What support will I get, and by when?
  • What is the review period and who will review?
  • What happens if the standard is not met?
  1. Ask in writing for the policy being used and the standard you are being measured against.
  2. Ask for the evidence of the shortfall and any dates, incidents or data relied on.
  3. Agree objectives that are specific, measurable and realistic, and a review date.
  4. Record the support offered: training, mentoring, adjustments, Occupational Health referral.
  5. Attend each review meeting with a union rep or colleague and ask for notes afterwards.
  6. If you disagree with a warning or decision, appeal in writing within the time stated in the letter.

When health, disability or life events are behind the performance dip

In shortPerformance dips often have a cause; if a health condition is involved the Equality Act duties apply, so tell HR or Occupational Health in writing.

Poor performance is often a symptom. Employers are expected to ask why performance has fallen, not just that it has.

Equality Act 2010, section 20
Reasonable adjustments, if a health condition is involved and it may be a disability.
Equality Act 2010, section 15
No unfavourable treatment because of something arising from the disability, unless the employer can show proportionality. A performance target applied without regard to a known disability can be indirectly discriminatory or can fail to meet the adjustment duty. See our guide on sickness absence for how these provisions work in practice.
  • Illness
  • Bereavement
  • Caring responsibilities
  • A difficult prisoner population
  • Relentless short staffing
  • An unsupported move to a new wing
  • An adverse incident

After a traumatic incident

Where performance has fallen after a traumatic incident, such as a serious assault, a death in custody or a use-of-force incident, ask for support through the Employee Assistance Programme and for Occupational Health. A manager who responds to trauma with a performance process may be acting inappropriately, and a union rep can raise that.

Where the incident involves a use-of-force allegation or similar, remember it may also trigger a conduct process; see use of force allegations.

Performance, probation and new starters

In shortPerformance concerns in probation are handled under an unpublished instruction, and short service does not remove protection against discrimination or whistleblowing detriment.

If you are a new officer, performance concerns may arise during probation. PSI 11/2014, Employee Induction and Probationary Periods, is not published, and the length of an England and Wales probationary period and how performance is assessed are not verified here. Check your contract and your confirmation letters.

In practice probation tends to involve regular reviews against objectives and can lead to an extension or termination if standards are not met. Our guide to prison officer probation dismissal explains the position in detail, and the earlier piece on the first year as a prison officer shows what is normally expected.

Short service and dismissal claims

No minimum service

  • Capability concerns can still be unfair even if you are short-serving, if the real reason is discrimination, whistleblowing, pregnancy or another protected matter.

Ordinary unfair dismissal

  • Two years' service up to 31 December 2026.
  • Six months where the effective date of termination is on or after 1 January 2027, under SI 2026/559.

Performance and the wider conduct system: the lines that blur

In shortThe test between performance and conduct is intention and pattern, not the label a manager chooses, so raise skill gaps and mistakes early.

Some failures of performance cross a line into conduct or even corruption. The test is intention and pattern, not the label a manager chooses.

  • HMPPS counter corruption policy says that consistent failure or poor performance of searches, where related intelligence suggests deliberate failure, can constitute corrupt behaviour, whereas honest mistakes are performance or conduct issues.
  • Repeatedly failing to complete use of force statements can lead to performance management or formal discipline, according to the Use of Force Policy Framework.

Separate genuine skill gaps from wilful failure

  • If you are struggling with searching procedures, report writing or a technical skill, say so early and ask for training.
  • If you realise a mistake has been made, report it promptly: HMPPS counter corruption policy encourages early disclosure by staff who have fallen short before things escalate.
  • A concern raised early is normally treated more favourably than one discovered later, although no outcome can be promised.

Appeals, tribunals and time limits

In shortUse the appeal named in your letter and take advice on dates, because the tribunal limit is usually 6 months from 1 October 2026 and Acas conciliation comes first.

If you receive a formal warning or are dismissed, the letter should tell you how to appeal and by when. Use it. In HMPPS conduct cases an appeal is available against any formal disciplinary decision, and the Acas Code says an appeal should be heard by someone not previously involved where possible.

The E&W appeal deadlines for performance matters are not verified, so read your letter carefully and diarise the date.

Employment tribunal rules in transition

  1. From 1 October 2026Six-month time limit

    For most claims, replacing three months, according to the Government timeline update of 25 September 2026. Early conciliation through Acas must come first.

  2. To 31 December 2026Two-year qualifying period

    For ordinary unfair dismissal.

  3. From 1 January 2027Six-month qualifying period

    The cap on compensation is removed from that date.

Realistic outcomes and how to approach them

In shortMost processes end in improvement, an expired warning or leaving; think carefully before resigning and keep records.

Compensation, when awarded, depends on loss and conduct. Keep perspective: being told you are not performing is distressing, but a formal process is also an opportunity to get a clear statement of what is expected and support to deliver it.

Use it, keep records, take advice and avoid reacting in ways that turn a performance issue into a conduct one.

  • You improve and the process is closed.
  • A formal warning is issued and then expires.
  • You leave, by redeployment, resignation or, rarely, dismissal.
  • The real problem is health or workplace stress and the right response is adjustment, or ill-health retirement under the pension scheme, see prison officer ill-health retirement.

Thinking about resigning

Performance process

  • Resigning avoids a dismissal on your record, but gives up any right to challenge it.
  • In some circumstances resignation can be treated as a constructive dismissal claim, a complex legal route that needs advice.

Conduct element

  • Resignation does not stop that process.

Frequently asked questions

What is the HMPPS poor performance policy?

It is PSI 12/2013, NOMS Policy on Managing Poor Performance, listed as extant but not published on gov.uk. Staff access it through HR or the intranet. We have not seen its stages or timescales and do not state them, so ask for the current version and any local guidance.

Is poor performance misconduct?

Not normally. HMPPS conduct policy tells managers to distinguish misconduct from performance and capability. Honest mistakes and lack of skill are performance matters, whereas deliberate or reckless breaches are conduct. If you are unsure which process you are in, ask in writing which policy applies.

Can I be put on the Exclusions Register for poor performance?

The Exclusion from Working for HMPPS Policy Framework states that poor performance alone is not a reason to exclude. Exclusion relates to dismissal for gross misconduct, or misconduct that poses a safety or security risk, and applies to conduct, not capability.

Can I be dismissed for poor performance as a prison officer?

Yes in principle, but official statistics show such dismissals are very rare: the June 2026 workforce tables suppress the figures as 2 or fewer, and at most 10 in any 12 months for Band 3 to 5.

A dismissal should follow a fair process with a chance to improve, and you may be able to challenge it if you have the qualifying service.

Can my union rep come to a capability meeting?

You have a statutory right to be accompanied at meetings that could result in a formal warning or other disciplinary action, and the Acas Code treats poor performance in that context.

A fellow worker or union representative can address the meeting but not answer for you. Ask for the invitation to state the purpose of the meeting.

What if my performance fell because of my health?

Tell HR and Occupational Health in writing and ask for reasonable adjustments. If your condition is a disability, the Equality Act 2010 prohibits unfavourable treatment arising from it unless justified, and requires reasonable adjustments. Whether it is a disability depends on its effects, so get advice from your union or Acas.
