What Happens If You Fail the Train Driver Psychometric Test?

Your Result Is Recorded — and Shared

The most important thing to understand about the train driver assessment is that your result does not sit privately with the operator you applied to. A central record of all candidate assessments is maintained across the industry, and under RSSB standard RIS-3751-TOM — the standard that governs UK train driver selection — participating operators can access that record before offering a candidate an assessment slot.

Assessment results are valid for five years from the date of the assessment and are recorded on a national database. A failed result is part of that record, so a fail at one operator does not just affect your application there — other operators check the database when you apply.

Understanding this is not meant to be alarming. It is meant to explain why your first attempt matters, and why adequate preparation before you walk into an assessment centre is not optional.

Attempt Limits and Waiting Periods

Under RSSB's rules from 7 December 2024, new candidates get three attempts at the standard psychometric assessment, and anyone who sat any part of it before that date gets two. A second attempt can take place at least 1 year after the first failed attempt; a third only 5 years after the first failed attempt and at least 1 year after the second. After the final failed attempt, you cannot have any more attempts at the process (RSSB candidate FAQ, Q19–20).

If you want to be considered for re-assessment, contact your prospective employer; they check the national database and tell you what you will need to sit.

The key takeaway is that attempts are a finite resource. A candidate who sits unprepared and fails is in a materially different position from a candidate who has not yet sat — they have used one attempt and must wait at least a year before a second.

Which Tests Cause the Most Failures

Not all train driver tests trip candidates up equally. Understanding where failures cluster helps you focus your preparation — whether before a first attempt or a resit.

The Vigilance test is often cited by candidates as the hardest. The reason is attentional fatigue: candidates who have never practised a full-length session often start strongly but miss more changes later on. Repeated full-length practice helps you get used to it.

The ATAVT is another common sticking point. The brief-flash format is disorienting on first exposure, and candidates who encounter it without prior familiarity can freeze or fall into poor response habits. Practice with brief exposures helps.

The TRP1 catches candidates who approach it as a reading comprehension exercise. The passage is understandable — but the questions do not test understanding, they test precise recall of specific numbers and conditions. Reading without deliberately memorising detail is the most common TRP1 failure mode.

What to Do After a Failed Result

In the days after a failed assessment result, the practical priorities are: establish the waiting period that applies to you, find out which tests you underperformed on if possible, and begin a structured preparation programme for your resit.

Operators sometimes provide limited feedback on which components of the battery were weak — ask specifically. If you can identify the test or tests that brought your result down, your preparation can be targeted rather than general.

• ✓Contact the operator to confirm the exact waiting period before you can resit
• ✓Ask whether any feedback is available on which components you underperformed on
• ✓Begin full-length Vigilance practice sessions immediately — this is the most time-dependent improvement and builds over weeks, not days
• ✓Practise brief-flash scene tasks until the format feels familiar
• ✓Practise TRP1 using the read-then-cover-then-recall method across several different passages
• ✓In the weeks before your resit, build up to long practice sessions to get used to the load of sitting the full battery

If You Have Not Sat Yet: Use This Information Now

If you are reading this before your first train driver assessment, you are in the ideal position: you can still ensure your first attempt is a properly prepared one.

Every improvement described above — Vigilance stamina, ATAVT familiarity, TRP1 retention strategy — is accessible before your assessment day. The candidates who pass on their first attempt are almost always the ones who prepared specifically for what the tests involve, not those with higher general intelligence or better background knowledge.

The format is learnable. The stamina is buildable. Make your first attempt count.
