Train Driver Psychometric Tests: The Complete 2026 Practice Guide
Quick answer
UK train driver psychometric tests are a battery of cognitive and psychomotor assessments — most commonly the Vigilance Test (WAFV), ATAVT, TRP1, Group Bourdon, TEA-OCC and a 2-hand Coordination test, usually preceded by an online Situational Judgement Test (SJT). They measure sustained attention, perception, rule retention, concentration and coordination rather than academic knowledge, and every one of them improves with realistic practice beforehand.
If you are applying to become a UK train driver, the psychometric tests are the part of selection most likely to decide whether you progress — and the part most candidates underestimate. They are not academically hard, but they measure things you rarely use day to day: holding concentration for 30 unbroken minutes, taking in a whole traffic scene in a single second, or absorbing a page of rules and recalling exact numbers from memory. This guide explains every test you might face, how the assessment is structured, where candidates trip up, and how to practise each one effectively before the real thing.
What are the train driver psychometric tests?
Train driver psychometric tests are standardised assessments used by GB train operating companies (and London Underground) to measure the cognitive and psychomotor abilities a safe driver needs. Most operators use a battery built and administered by the OPC (Occupational Psychology Centre), supplemented by an online screening stage.
Crucially, these tests do not assess knowledge, maths ability, or rail experience. They assess raw, trainable abilities — sustained attention, perceptual speed, working memory, concentration and fine motor control. That is why career-changers with no background in rail can pass them, and why practising the format in advance makes such a measurable difference: you are not learning facts, you are conditioning the underlying skills and removing the surprise of an unfamiliar format.
The full list of train driver psychometric tests
The exact mix varies slightly by operator and over time, but the tests you are most likely to encounter are:
- ✓Situational Judgement Test (SJT) — an online, scenario-based screen usually completed at home before the assessment centre. Tests judgement around safety, procedure and communication.
- ✓Vigilance Test (WAFV) — a continuous 30-minute test of sustained attention where you respond each time a grey square briefly turns black. Widely considered the hardest component.
- ✓ATAVT — a hazard-perception test where a traffic scene flashes for about a second and you identify which elements (vehicles, pedestrians, signs, cyclists) you saw.
- ✓TRP1 — Trainability for Rules and Procedures: you read a fictional rules passage, then answer 18 questions from memory about specific numbers and procedures.
- ✓TRP2 — the second part of the rules test, used by some operators: you apply rules about fictitious train-cab dials to work out the order in which the dials should be checked.
- ✓Group Bourdon — a dot-cancellation concentration test where you mark groups containing exactly four dots across timed sheets.
- ✓TEA-OCC — a divided-attention test involving counting audio tones, searching for information, and doing both at once.
- ✓2-Hand Coordination — a psychomotor test where you guide a dot along a track using two controls at once, measuring fine motor control and hand independence.
- ✓SCAAT — a sustained concentration and attention test used by some operators, where the matching rule gets harder partway through.

How the OPC assessment is structured
For most operators the journey runs in a predictable order. First an online application, then the online Situational Judgement Test as an early filter. Candidates who clear the SJT are invited to an assessment centre, where the OPC psychometric battery is administered under standardised, timed conditions — usually a half or full day — typically alongside a structured competency interview. A medical examination follows for successful candidates.
The assessment centre is the stage most candidates underestimate. No single test is difficult in isolation, but holding accuracy and concentration across the entire battery — back to back, under observation — is genuinely demanding. Fatigue and lapses in the later tests catch out people who could have passed each one individually.
Which test is the hardest?
Most candidates and assessors agree the Vigilance Test (WAFV) is the toughest, simply because 30 minutes of unbroken concentration with no feedback is something almost nobody does in daily life. Lapses creep in around the 15–20 minute mark, and missed signals or false alarms accumulate quickly.
The TRP1 catches people out for a different reason: candidates read the passage like a story rather than memorising specific numbers, then cannot recall the detail the questions demand. The ATAVT punishes passive looking — you have to actively scan all element types in the second the scene is visible. Knowing each test's specific failure mode in advance is half the battle.
How to practise the train driver psychometric tests
Because these tests measure trainable abilities, deliberate practice produces real gains — but only if you practise the right way for each test:
- ✓Vigilance: build up your concentration stamina gradually, extending practice sessions from 10 minutes towards the full 30, and train yourself to respond within about 1.5 seconds without false alarms.
- ✓ATAVT: drill active scanning — deliberately check for every element type (vehicles, pedestrians, signs, cyclists, motorcycles) in each flash rather than fixating on one.
- ✓TRP1: read for retention, not comprehension — read the passage twice, fix the exact numbers and conditions in memory, then answer with the passage covered.
- ✓Group Bourdon: practise on timed sheets to build a steady, systematic left-to-right pace that balances speed with accuracy.
- ✓TEA-OCC and Coordination: rehearse the divided-attention and two-handed formats so they feel familiar under pressure on the day.
- ✓Across all of them: finish your preparation with full, realistic simulations rather than cramming new techniques in the final days.
A simple preparation plan
If you have a few weeks before your assessment, a light daily routine beats occasional long sessions. Concentration and attention improve with frequency, not intensity.
A sensible structure: practise the Vigilance Test most days, building duration over time; rotate the ATAVT, TRP1 and Group Bourdon every other day; and add the TEA-OCC and Coordination tests if your operator uses them. Review your results each time to see which skill is lagging, and focus the next session there. In the final few days, switch from drills to full mock runs under realistic, distraction-free conditions so the real assessment feels routine.
Our site includes free demos of the core tests (no account needed) and full interactive simulations of the complete battery, so you can practise each test the way it actually appears on the day. The dedicated guides linked below break down each individual test in depth.
Frequently asked questions
How many psychometric tests do train drivers take?
Most candidates face an online Situational Judgement Test followed by an OPC battery of around four to six tests — commonly the Vigilance Test, ATAVT, TRP1 and Group Bourdon, with some operators also using the TEA-OCC, SCAAT and a 2-hand Coordination test. The exact mix varies by operator.
Can you practise train driver psychometric tests online?
Yes. The Vigilance Test, ATAVT, TRP1, Group Bourdon and other OPC tests can all be practised online with realistic simulations. Because the tests measure trainable abilities like attention and perception, practising the format in advance reliably improves performance.
How hard are the train driver psychometric tests?
They are not academically difficult, but pass rates are typically only around 40–60% on first attempt because the tests demand sustained concentration and accuracy that most people are not used to. The 30-minute Vigilance Test is usually cited as the hardest.
What is the pass mark for the OPC tests?
The OPC does not publish official pass thresholds, and standards can vary by operator and role. Rather than a fixed percentage, your scores are benchmarked against the levels expected of safe, effective drivers — which is why consistent accuracy across the whole battery matters.
How long does the train driver assessment take?
The OPC test battery is usually completed in a half to full day at an assessment centre, often alongside a competency interview. The online Situational Judgement Test beforehand typically takes 10–20 minutes.
