Train Driver Assessment Attempt Rules: What Happens If You Fail?

Official rules on train driver psychometric test attempts. Learn about the 3-attempt maximum, waiting periods between tests, and what to do if you fail. Based on RIS-3751-TOM.

December 2025By TDF Research Team

Understanding Attempt Rules

One of the most common questions from aspiring train drivers is: "What happens if I fail the psychometric tests?" The rules are clearly defined in RIS-3751-TOM, the official industry standard.

The Three-Attempt Rule

The official standard states that candidates are allowed a maximum of three attempts at the psychometric assessment.

What This Means

  • You have up to three chances to pass
  • After three failures, you cannot reattempt the assessment
  • This rule applies across all Train Operating Companies
  • Results are tracked industry-wide

Why Only Three Attempts?

The limit exists to:

  • Ensure assessments measure genuine aptitude, not test familiarity
  • Prevent candidates from simply memorising test patterns
  • Maintain the validity and reliability of the selection process
  • Ensure safety standards are upheld

Waiting Periods Between Attempts

If you fail, you must wait before trying again. RIS-3751-TOM requires significant time intervals between attempts:

Purpose of Waiting Periods

  • Allow time for genuine development of abilities
  • Prevent "practice effects" from recent exposure
  • Ensure each attempt is a fair assessment
  • Give candidates time to prepare properly

Typical Waiting Times

While specific periods vary by TOC, expect:

  • Several months between first and second attempt
  • Longer gap before a third attempt
  • Some TOCs require 6-12 months between attempts

What Happens After Each Outcome

After Your First Attempt

If You Pass:

  • Your results are valid for five years
  • You can proceed with the rest of the selection process
  • Results may be transferable to other TOCs

If You Fail:

  • Required waiting period before retaking
  • Use the time to practice and prepare
  • Consider getting feedback if available
  • Don't rush into a second attempt unprepared

After Your Second Attempt

If You Pass:

  • Proceed as normal
  • Results valid for five years

If You Fail:

  • This is your final chance
  • Longer waiting period usually required
  • Seriously assess your preparation strategy
  • Consider whether the role is right for you

After Your Third Attempt

If You Pass:

  • You've made it - proceed with selection

If You Fail:

  • No further attempts permitted
  • You cannot become a train driver through this pathway
  • Consider related roles in the rail industry

Do Results Transfer Between TOCs?

Yes, with important conditions:

Within Validity Period

  • Results are generally valid for five years
  • Can be transferred between Train Operating Companies
  • TOCs may request your previous results

Failed Attempts

  • Failed attempts are also recorded
  • TOCs can access your assessment history
  • You cannot "reset" your attempt count by applying elsewhere

Important Implication

Don't waste attempts by applying to multiple TOCs simultaneously and failing repeatedly - each attempt counts toward your total.

How to Make Each Attempt Count

Given the limited attempts, preparation is crucial:

Before Your First Attempt

1.Practice extensively - use all available preparation resources

2.Understand the tests - know what each assessment measures

3.Build the skills - work on attention, memory, reaction time

4.Be realistic - only attempt when genuinely ready

5.Get rest - arrive at the assessment well-rested

If You Need to Retake

1.Analyse what went wrong - which tests were difficult?

2.Target weak areas - focus practice on problem areas

3.Use the waiting period - genuinely develop abilities

4.Consider professional support - coaching or preparation courses

5.Don't rush - wait until you're truly prepared

Reasonable Adjustments Don't Affect Attempts

If you receive reasonable adjustments (for neurodiversity or disability), this doesn't change the attempt rules:

  • You still have maximum three attempts
  • Adjustments help you demonstrate your abilities
  • The same standards apply for safety-critical aspects
  • Adjustments are about fairness, not lowering requirements

Special Circumstances

Mitigating Circumstances

RIS-3751-TOM requires TOCs to have policies for unexpected events during assessments. If something significant happens (illness, emergency, technical failure), you may be able to:

  • Have the attempt discounted
  • Reschedule without using an attempt
  • Request special consideration

Note: This is at the TOC's discretion and requires evidence of genuine mitigating circumstances.

Previous Experience

If you have prior train driving experience, there's a transfer process for your safety information. Previous employers must provide details about your history, which may affect how your current application is assessed.

Key Takeaways

  • Maximum 3 attempts - this is industry-wide and tracked
  • Waiting periods required - use them to prepare properly
  • Results last 5 years - plan your applications strategically
  • Attempts count everywhere - you can't reset by switching TOCs
  • Prepare thoroughly - make each attempt count
  • Use mitigating circumstances - if genuine issues occur

Your Best Strategy

Given these rules, the smartest approach is:

1.Prepare extensively before your first attempt

2.Only apply when you're genuinely ready

3.Use practice tests to assess your readiness

4.Don't waste attempts - one well-prepared attempt is better than three rushed ones

5.If you fail, use the waiting period productively
