What to Expect on Your Train Driver Assessment Day
Quick answer
The train driver assessment day typically includes the train driver psychometric test battery (Vigilance, ATAVT, TRP1, and Group Bourdon), a competency-based interview, and a medical examination — all on the same day at an assessment centre. Arriving well-rested and having practiced all four train driver tests in advance are the most effective ways to improve your performance.
The train driver assessment day is the most important stage of the entire application process. Everything before it — the application form, the online sift, the invitation letter — has been leading to this. Most operators pack the psychometric tests, a medical examination, and a competency interview all into a single day at an assessment centre. Knowing exactly what to expect before you walk through the door makes an enormous difference to how you perform. This guide takes you through each stage, in the order you are likely to encounter it.
Before the Day: What to Prepare
Most operators send an assessment invitation two to four weeks in advance. Read it carefully — it will tell you the venue, start time, what to bring, and the format of the day. Some operators publish a candidate information pack at this stage; if one is available, read it thoroughly.
Practical preparation matters. Plan your route the day before and give yourself extra travel time — arriving late to a train driver assessment is not a good look. Dress smartly but comfortably; business casual is appropriate at most operators. Bring photo ID (passport or driving licence), your National Insurance number, and any documents specified in your invitation letter such as proof of your driving licence or right to work.
The most valuable preparation you can do in the weeks before is to practice the train driver psychometric tests. The Vigilance Test and ATAVT are unlike anything most people have encountered before, so familiarity with the format matters. Knowing the format in advance helps you stay calm and in control on the day.
- ✓Read your invitation letter in full — format and requirements vary by operator
- ✓Plan your route and aim to arrive 15 minutes early
- ✓Bring photo ID, NI number, and any documents requested
- ✓Practice the train driver tests in the weeks beforehand
- ✓Get a good night's sleep — sustained attention tests are harder when tired
The Train Driver Psychometric Tests
The train driver psychometric battery is the centrepiece of the assessment day and the stage that tends to feel most daunting. It is a mix of paper-and-pencil and computer-based tests, typically run in a dedicated testing room with an invigilator present. You will usually be seated at individual workstations with some separation from other candidates.
RSSB standard RIS-3751-TOM sets out the standard battery used across GB mainline rail: Group Bourdon and TEA-Occ (attention), the WAFV vigilance test, TRP1b and TRP2 (rules and procedures), the ATAVT (perception), 2HAND (hand coordination), a situational judgement exercise (SJE) and a multi-modal interview (MMI). Each company chooses its own pass marks and may add tests or use an enhanced standard.
Session lengths and individual test timings aren't published and vary by assessment centre. You will receive instructions for each test before it begins. The train company will also give you the official approved practice materials at least a week before your assessment — work through them, as well as any other practice you do.
- ✓A mix of paper-and-pencil and computer-based tests, in a supervised room
- ✓Standard RSSB battery: Group Bourdon, TEA-Occ, WAFV, TRP1b, TRP2, ATAVT, 2HAND, SJE and MMI
- ✓Companies choose their own pass marks and may add tests

The Vigilance Test (WAFV) — What It's Actually Like
The Vigilance Test is widely reported to last about 30 minutes. You watch a simple display, and at random intervals it briefly dims slightly. Your job is to press the response key the instant you see it change. That is the entire test — for a long, continuous session.
In practice, the test is far harder than it sounds. The changes are brief and the intervals between them are unpredictable — sometimes a few seconds, sometimes several minutes. Maintaining genuine focus for the whole session is genuinely demanding, especially as the first ten minutes feel manageable and it is easy to slip into a less attentive state.
The exact scoring isn't published, but the test records the changes you detect, the ones you miss and your reaction times, so false alarms and misses both matter. The key is to stay consistently alert throughout rather than trying to anticipate when the next change will come.
- ✓Widely reported as about 30 minutes, continuous
- ✓A simple display briefly changes at random intervals
- ✓Press the response key immediately when you see it change
- ✓Detections, misses and reaction times are recorded
- ✓Stay alert throughout — don't try to anticipate the next change
The ATAVT — What It's Actually Like
The ATAVT (Adaptive Tachistoscopic Traffic Perception Test) shows traffic scenes on screen very briefly. After each image disappears, you choose from five given answers to say what was in it. The test is adaptive — the exposure time changes with your performance — and the publisher gives the test time as about 10 minutes. The number of scenes used in rail isn't published.
The exposure is very short. The skill the test measures is rapid, organised visual scanning — taking in a complex scene at a glance and accurately encoding what you saw. Candidates who have not practiced often find themselves uncertain about what they actually saw versus what they think might have been there. Repeated exposure to the format trains you to scan more deliberately.
The exact scoring isn't published. Work systematically through the answer options after each image rather than answering randomly, and follow the instructions you are given on the day.
- ✓Traffic scenes flash up very briefly; the exposure time adapts
- ✓After each scene, choose from five answers what was present
- ✓Things like vehicles, pedestrians, traffic lights and signs
- ✓About 10 minutes, according to the publisher
- ✓Scan deliberately and systematically — familiarity helps
The Medical Examination
Most operators include a medical examination on the assessment day, conducted by an occupational health professional. The medical is governed by the Train Driving Licences and Certificates Regulations 2010 and covers a defined set of standards — the same requirements apply across all UK operators.
The examination typically includes a vision test (including colour vision and visual acuity), a hearing test, blood pressure and general cardiovascular checks, a urine test, and a review of your medical history. You will be asked about any conditions, medications, or previous health issues. Be honest — concealing relevant medical information is grounds for immediate disqualification and can affect future applications.
Common reasons for medical concerns include colour vision deficiency (certain types will disqualify you), certain cardiovascular conditions, epilepsy, insulin-dependent diabetes, and some psychiatric conditions. If you have a pre-existing condition, it is worth researching the medical standards before applying rather than discovering a problem on assessment day. The full standards are published by the Office of Rail and Road.
- ✓Standardised medical standards across all UK operators (Train Driving Licences Regulations 2010)
- ✓Includes: vision (acuity and colour), hearing, blood pressure, urine test, medical history
- ✓Colour vision deficiency may disqualify — check requirements before applying
- ✓Be honest about medical history — concealment is grounds for disqualification
- ✓Full standards published by the Office of Rail and Road (ORR)
The Competency Interview
The competency interview is typically the final stage of the assessment day and is conducted by one or two interviewers, usually a recruitment specialist and a manager from the operating company. Most operators use a structured behavioural interview format — you will be asked to give specific examples from your past experience for each question.
Questions are based on the core competencies required of a train driver: safety awareness, attention to detail, following rules and procedures, communication, working under pressure, and motivation for the role. The STAR framework (Situation, Task, Action, Result) is the standard approach — describe the context briefly, explain what was required, detail what you specifically did, and explain the outcome.
You do not need a railway background to answer these questions well. Relevant examples can come from any area of work or life — a previous job, a volunteer role, a difficult personal situation — as long as they genuinely demonstrate the competency being asked about. Prepare at least two or three examples for each key area in advance.
- ✓Structured behavioural interview — specific examples required, not hypotheticals
- ✓Key competencies: safety, attention to detail, rules/procedures, communication, motivation
- ✓Use the STAR framework: Situation, Task, Action, Result
- ✓Examples can come from any area of life — railway experience is not required
- ✓Prepare 2 to 3 examples per competency area in advance
After the Assessment Day
Most operators aim to communicate outcomes within one to three weeks of the assessment day, though this varies. Some give a combined result covering all stages together.
If you are successful, you will typically receive a conditional offer of employment subject to reference checks, a Disclosure and Barring Service (DBS) check, and final medical clearance. Training will then be discussed and a start date agreed.
If you are unsuccessful, some operators will give brief feedback on which stage you did not meet the required standard. If the psychometric tests were the stumbling block, remember that results are shared across operators and RSSB's attempts rule applies: a second attempt can take place at least 1 year after the first failed attempt. Use that time for targeted practice.
- ✓Results typically communicated within 1 to 3 weeks
- ✓Successful candidates receive a conditional offer subject to DBS and references
- ✓If unsuccessful, some operators provide limited feedback on which stage
- ✓A psychometric fail means waiting at least 1 year before a second attempt (RSSB rule)
- ✓You can reapply — targeted practice before the next round is the best approach
Frequently asked questions
How long does the train driver assessment day last?
Most train driver assessment days run for between four and seven hours, depending on the operator and the number of stages included. The train driver psychometric tests alone typically take two to three hours. Allow a full day and do not make plans for the afternoon if your assessment starts in the morning.
Can I fail the medical on assessment day?
Yes. The medical examination uses standardised standards set out in the Train Driving Licences and Certificates Regulations 2010. Common reasons for not meeting medical standards include certain types of colour vision deficiency, some cardiovascular conditions, and a history of certain neurological or psychiatric conditions. If you have any concerns about your health, it is worth reviewing the ORR medical standards before applying.
Do I need railway experience to pass the competency interview?
No. Competency interviews for trainee train driver roles are designed to be answered using examples from any background. You will not be expected to have operational railway knowledge — that is what the training programme is for. What matters is that your examples clearly demonstrate the required competencies: safety awareness, attention to detail, following procedures, communication, and motivation.
How hard are the train driver psychometric tests?
The train driver tests are unfamiliar in format, which is a big part of what makes them difficult. The Vigilance Test requires a long session (widely reported as about 30 minutes) of sustained concentration on a near-featureless screen. The ATAVT shows complex scenes very briefly. Practising similar tasks beforehand means you are not encountering it for the first time on assessment day.
What happens if I fail the assessment day?
If you failed the psychometric tests, RSSB's attempts rule applies: a second attempt can take place at least 1 year after the first failed attempt, and new candidates get three attempts in total (two if you sat any part before 7 December 2024). Some operators provide brief feedback on which stage you did not meet the required standard. If the train driver psychometric tests were the reason, structured practice before your next attempt is the most effective preparation.
What should I bring to a train driver assessment day?
At minimum: photo ID (passport or driving licence), your National Insurance number, and any documents specified in your invitation letter. Dress smartly. Eat a proper meal beforehand — the day is long and the psychometric tests require genuine concentration. Avoid alcohol the night before. Arrive early.
