What Really Happens at a Train Driver Assessment Day
Assessment days are where most train driver candidates fail. Not because they are unprepared, but because they don't understand what is actually being scored. This article walks through a typical UK TOC assessment day in chronological order — from arrival through psychometric battery to MMI exit — and the small behavioural mistakes that disqualify candidates before lunch.
- 08:30 arrival — the assessment starts the moment you sign in.
- Group briefing — observers are noting questions you ask (and don't ask).
- Psychometric battery — Group Bourdon, vigilance, fault detection.
- Lunch — informal conversation is observed too.
- MMI — 6–8 STAR competency questions in 30 minutes.
- Closing brief — your final questions to the panel are themselves a question.
