How to become a probation service officer
A probation service officer (PSO) manages a caseload of people on community sentences who are assessed as lower risk, and supports qualified probation officers on harder cases. HM Prison and Probation Service lists a starting salary of £28,064 for a 37-hour week, plus London weighting of £4,505 where it applies. You do not need a degree: the stated minimum is GCSEs at grade C or equivalent.
What PSOs do
Each PSO has a caseload, which HMPPS says is typically 40 to 60 cases built up gradually. You hold regular appointments, check people are complying with their orders, complete risk assessments and case records, and refer people to housing, employment and substance misuse services. You also liaise with partner agencies and families, record breaches and work with probation officers on how to respond. Some PSOs attend court and write reports when required.
Most appointments take place in probation offices. The probation officer guide covers the higher-risk, degree-level role you can progress to.
Entry requirements
HMPPS lists GCSEs at grade C or equivalent as the minimum and asks for no degree. It wants empathy, resilience, organisation and some understanding of the criminal justice system. The National Careers Service adds that experience with vulnerable people or challenging behaviour helps, which you can gain through paid or voluntary work with charities that support people leaving prison.
Another way in is to start as a case administrator in a probation office and train on the job.
Selection process
HMPPS describes five stages:
- An online application covering experience, skills and motivation.
- A sift against the essential criteria, which typically takes about two weeks.
- A half-day assessment centre with group exercises, a written task and an interview.
- Pre-employment checks: references, an enhanced DBS check and security clearance.
- A start date.
Our assessment centre guide explains what group exercises usually test, and the DBS levels guide covers what an enhanced check involves.
Training
New PSOs start with a 12-week induction covering probation practice, risk assessment, motivational interviewing, safeguarding and the case management systems. You then shadow experienced colleagues before building up a caseload. The National Careers Service says new starters complete the Level 3 Diploma in Probation Practice in their first 12 months, which qualifies them as a PSO.
Pay, leave and hours
The £28,064 starting salary is for 37 hours a week. HMPPS lists 25 days’ annual leave plus 8 public holidays, rising to 30 days with service, and says flexible hours and part-time work are available in many locations. The National Careers Service gives a wider typical range of £28,000 to £34,000.
Skills the role calls for
The National Careers Service lists knowledge of public safety and security, excellent verbal communication, patience and the ability to stay calm under stress, initiative, thoroughness and attention to detail, leadership and flexibility. Day to day that means keeping accurate records on every contact and working with housing, drug and alcohol services and employers. The National Careers Service also lists supporting victims of crime, supervising residents in approved accommodation, and supporting people before and after release from prison among the tasks.
The mix of those tasks varies by team, so ask at interview what a typical week looks like.
Related roles
The National Careers Service lists probation officer, youth worker, family support worker, police officer and social worker as related careers. If you are weighing options, see our guides to youth workers, family support workers and police constables. HMPPS says pay is reviewed regularly, so check the current figure on the vacancy.
Moving up
HMPPS sets out a typical path. In the first three years you take on more complex cases and build specialist knowledge. Between years 3 and 5 you can become a senior PSO or apply for the trainee probation officer programme, which comes with study time and funding support. The Professional Qualification in Probation (PQiP) then leads to qualified probation officer status, managing cases at every risk level. Qualified probation officers start at £35,130 to £39,379 on the HMPPS page.
If you want the justice sector but a custody setting, compare it with prison officer work. For work with younger people, see youth justice worker jobs.
