What Happens If You Fail the OPC Psychometric Test?
Failing the OPC psychometric test is one of the most deflating outcomes in the train driver application process — especially because the consequences extend further than most candidates expect. Your result doesn't just affect your application with one operator. It can affect your eligibility across the entire industry for years. Here's exactly how the system works, and what your options are.
OPC results are recorded and shared
This is the single most important thing to understand before you sit the OPC assessment: your results are not just between you and the operator you're applying to.
The OPC (Occupational Psychology Centre) maintains records of all candidate assessments. Under RSSB standard RIS-3751-TOM, which governs UK train driver selection, OPC results are valid for five years from the date of the assessment — and participating operators can check whether you have a result on record before offering you an assessment slot.
In practice, this means a failed result at one operator can effectively put you on hold across the industry for the duration of the validity period, or until the waiting period specified in the standard has elapsed.
How many attempts are you allowed?
The RSSB standard imposes limits on the number of attempts candidates can make within a given period. While the exact rules are updated periodically, the general principle is that candidates are permitted a limited number of sittings (typically two) within a defined period, after which a waiting period applies before they can attempt the assessment again.
Individual operators may apply additional restrictions beyond the RSSB minimum. Some operators require a mandatory gap between attempts even on a first failure. It is worth checking the specific policy with any operator you are applying to.
The practical implication: your first attempt matters enormously. A candidate who sits unprepared and fails is not in the same position as a candidate who hasn't sat yet — they have used one of a limited number of attempts and may face a waiting period before they can try again.
Which tests are most commonly failed?
Not all tests in the OPC battery present equal difficulty for the average candidate. The Vigilance test catches many candidates off guard — not because it is conceptually complex, but because the 30-minute sustained attention demand is genuinely hard to perform at without specific preparation. Many candidates who are fully capable of passing in normal circumstances underperform simply because they have never experienced the full-length format before.
The ATAVT is the second most commonly challenging test. The 1-second flash format is disorienting the first time, and candidates who walk into it without prior exposure often freeze or develop poor selection habits under pressure.
The TRP1 tends to trip up candidates who approach it as a reading comprehension exercise rather than a memorisation task — they understand the passage but cannot recall the specific numbers when the questions appear.
What should you do if you've failed?
If you have recently failed the OPC assessment, the first step is to establish exactly where you stand. Contact the operator and ask for clarity on the waiting period that applies to you specifically.
Use whatever time you have productively:
- ✓Identify which test(s) caused the failure — if you know, focus your preparation there specifically
- ✓Build genuine stamina for the Vigilance test through repeated full-length practice sessions — this is the most time-dependent improvement and cannot be rushed
- ✓Practise the ATAVT under real 1-second flash conditions until the format feels familiar rather than disorienting
- ✓Work through multiple TRP1 sets, actively practising the read-then-recall method rather than passive reading
- ✓Approach your next attempt with the format already deeply familiar — surprise is the enemy of performance on any timed test
If you haven't sat yet — prepare before your first attempt
If you are reading this before your assessment, you are in the best possible position: you can still ensure your first attempt is a prepared one.
The OPC battery tests skills that are directly trainable. Candidates who sit the full-length Vigilance test in practice before their assessment day consistently outperform those who don't. Candidates who have seen the 1-second ATAVT flash format before walking into the test centre perform better than those who encounter it for the first time under assessment conditions.
You only need to get this right once. Make your first attempt count.

Frequently asked questions
Do OPC results transfer between train operators?
Yes. OPC results are recorded centrally and are valid for five years. Operators can check whether you have a result on record before offering you an assessment slot.
How long do I have to wait after failing the OPC test?
The RSSB standard specifies a waiting period, but the exact duration can vary. Contact the operator you applied to for the specific policy that applies to your situation.
Can I appeal an OPC test result?
OPC results are based on standardised, computer-scored assessments. There is no formal appeal process for psychometric test scores. If you believe there was a technical or administrative error, contact the OPC directly.
Will failing the OPC at one operator affect my application to a different operator?
Potentially yes, for the duration of any mandatory waiting period. Results are held centrally and operators participating in the RSSB standard can check candidate history.
Is it possible to improve enough to pass on a second attempt?
Yes — particularly for the Vigilance test, ATAVT, and TRP1, where performance improves significantly with targeted practice. The key is understanding what specifically caused the failure and addressing it directly.
