Working as a prison officer is a pressured role that involves taking responsibility for the care of inmates, some of whom may be vulnerable individuals. Job candidates must be able to demonstrate good basic numeracy skills, plus personality traits and behaviours that align with the expectations of someone working in a position of authority.
The Prison Officer Selection Process (POST) has been designed to determine whether you are the right candidate to be a Prison Officer. Practice Aptitude Tests have put together online practice material, targeted at aspiring Prison Officers so that you can be equipped for your assessment. The initial stages of becoming a Prison Officer require you to complete an online application form. You will be expected to answer questions that determine whether you are eligible to become a Prison Officer. Once you have been accepted through to the next stage, you will receive an invite to complete the first stage of the POST. This will consist of 2-3 online tests and in the event you have successfully completed them, you will be invited along to the prison officer assessment day (otherwise known as RAD). At the assessment day, you will be faced with two tests; a prison officer maths test and a situational judgement test. We have provided some more detail about each of these tests below:
Finding out which tests your employer sets is the single most useful thing you can do before practising. There is a free sample question below.
Which tests you sit depends on the employer. These are the things worth doing whichever ones you are set.
The very first step in mastering the Prison Officer Selection Process is to understand the format of the exams. By using Practice Aptitude Tests, you can get a clear picture of what to expect. You’ll encounter the types of questions and the pacing, so there are no surprises on test day. Dive into the structure of the online tests and the assessment day challenges to ensure you’re as prepared as you can be.
Being a Prison Officer is unique, and the tests are designed to assess your suitability for the role. Spend time understanding the responsibilities and qualities required for a Prison Officer. Reflect on how the skills and attributes tested align with the day-to-day duties you’d perform. This insight can guide your preparation and help you approach the test questions with the right mindset.
To truly prepare for the POST, simulate the exam environment using Practice Aptitude Tests. Allocate dedicated time slots for practice, and ensure your setting is as close to the exam conditions as possible - quiet, uninterrupted, and timed. This habit not only helps you get used to the pressure but also aids in building your confidence and time management skills.
Everyone has areas they can improve. Identify your weaknesses early in your preparation process with our diagnostic tests and targeted practice exams at Practice Aptitude Tests. Focus on these areas with additional exercises and revision to turn your weak spots into strengths, ensuring a well-rounded performance across all aspects of the POST.
Test preparation goes beyond studying - your physical and mental well-being are paramount. Ensure you’re eating well, staying hydrated, and getting enough sleep in the days leading up to the test. A rested mind is more effective at problem-solving and critical thinking, both of which are crucial for success as a Prison Officer and when taking the selection tests.
This is the style of question our Prison Officer tests use. Pick an answer to see how you did.

The Prison Officer Selection Test, often referred to as POST, is a mandatory test for all applicants wishing to work in the prison service. It is designed to determine whether you are right for the role and has recently been developed to assess personality traits as well as skills and behaviours.
Prison officers are required to carry out numerical tasks as part of their role, so numeracy assessments are a key part of the POST.
You will also undertake psychometric tests to show how you respond to workplace situations and behave under pressure. Honesty and integrity is an utmost requirement for work as a prison officer.
You do not need any prior knowledge of the prison service or the specific role of a prison officer to pass the test.
To express your interest in joining the prison service, you must first submit an online application form. If you meet the minimum requirements and your initial application is successful, you will be invited to sit the POST.
The Prison Officer Selection Test is a remote test that can be taken from anywhere (providing you can access a computer with an internet connection).
You will receive a link to the test via email. The test takes around an hour to complete and you have seven days in which to submit your test.
The test is divided into multiple stages, as outlined below.
Stage one starts with a situational judgement test that assesses your behaviour when confronted with a typical prison workplace situation. This is followed by a numerical test to assess basic numeracy skills and mathematical ability.
If you are successful in stage one, you will be invited to move onto stage two.
Stage two presents a new addition to the Prison Officer Selection Test: a game-based assessment. This innovative format tests your natural behaviours and reactions.
The situational judgement test assesses your natural behaviours in the workplace. You will be presented with a typical work-related scenario along with multiple possible actions that you could take in response to that scenario.
You will be asked to order the actions to show which you think are the most effective to the least effective. You will have an allowance of 20 minutes to answer 16 questions.
The second section of stage one is the numerical reasoning test. You do not need a high level of mathematical knowledge to pass this test; just a good understanding of basic mathematical principles like multiplication, division, percentages and currencies.
You must also have a perfect grasp of the 24-hour clock as very accurate timekeeping is a skill needed for work as a prison officer.
The numerical reasoning test has a time allowance of 15 minutes and consists of 20 questions. You will be permitted to take in a pen, paper and a calculator to help you work out answers.
The test is not negatively marked, meaning that you won’t be deducted marks for incorrect answers – so if you are unsure, take an educated guess.
If you successfully complete stage one, you will move onto stage two, which is a new format of testing in the Prison Officer Selection Test.
You will receive unique login details that give you access to a games-based test that you can take on a computer or tablet. The purpose of this stage is to assess your natural responses in ‘real time’ as you are immersed in the game.
You are offered the chance to take as many practice tests as you like before sitting the actual test, so familiarise yourself with the format and process of the game before diving in.
The game has no time limit. Candidates usually take around 30 to 50 minutes to reach the end, passing through nine levels that all present different scenarios.
There are no right or wrong answers, so you don’t pass or fail this stage. Instead, you will receive a feedback report outlining your responses and what this reveals about your personality and behaviours.
If you successfully complete the Prison Officer Selection Test, you move onto the final round of the recruitment process: the assessment and recruitment centre day.
The day consists of further testing, similar to the POST, but often slightly more challenging. You will also be required to sit a literacy and language test that assesses your reading, writing and comprehension skills.
Examiners need to be sure that you have a good grasp of English and can read and apply written instructions, guidelines and reports accurately – all of these are requirements of day-to-day working life as a prison officer.
You will be required to:
Compare two texts and identify any errors, omissions or discrepancies.
Show that you can understand written rules and apply them to keep order in the prison
Look at an image or picture of a typical scene in a prison and later recall details about that scene
Read an extract of text and answer questions on it to demonstrate basic comprehension
Participate in role plays
You must also pass a fitness test and medical assessment. Finally, you will undertake a recorded interview to talk more about your suitability for the role.
1) Make sure you are at peak physical fitness
Prison officers are on their feet all day and often have to use physical strength in their job. Your general fitness and physical stamina will be assessed using a bleep test. You will also be asked to demonstrate upper body strength by handling heavy equipment used frequently in prisons.
2) Revisit basic mathematical principles
Refreshing your numeracy skills – particularly in addition, subtraction, division and multiplication – will prepare you for the numerical reasoning test. You can also take online numerical practice tests to familiarise yourself with the types of questions you might face.
3) Research what is involved in being a prison officer
Although you don’t need any prior knowledge to pass the assessments, you will be asked about why you want to join the prison service and what you can offer to the role. Having a basic awareness of what the job entails means you can prepare some answers beforehand.
4) Brush up on your literacy skills
Read all you can about the prison service to bring yourself up to date with any developments, news or current practices in the field and then rewrite your findings. Take online verbal reasoning practice tests to develop the reading, writing and comprehension skills you’ll be tested on during the assessment day.
5) Check the requirements of the tests
Before each stage of testing, double-check when and where you are sitting the test, what you can or cannot take with you, and if you need to do anything in particular beforehand.
What candidates ask us most often
You will need a good understanding of basic mathematical principles to be able to work as a prison officer, as you will need to draw upon these skills accurately in your everyday work.
Stage one of the tests has two parts. The situational judgement test has a time limit of 20 minutes and the numerical reasoning test allows 15 minutes.
Stage two, consisting of the game-based task, has no time limit, but typically takes around 30 to 50 minutes to complete.
If you fail the POST, you must wait six months before reapplying. If you fail only the fitness component of the test, you may retake it up to three times, as long as you have passed all the other components of the tests.

I like the test and I don't know why but I sometimes feel lazy, so the timing I would say is what I am not cool with.I nearly quit the test but I tried to keep focusing more on finding out the right answer. As it was my first time, I didn't find it easy.
The time for you to calculate was tight because the time was moving fast. And you probably have to understand the questions well, which you also don't have enough time to balance through thoroughly.
Fairly simple but easy to make mistakes if not concentrating
