TEA-OCC Test
Count tones. Match symbols. Both at once. — here is everything you need to know about the TEA-OCC Test before your c2c OPC assessment.
Why the TEA-OCC matters for c2c drivers
c2c operates services across London Fenchurch Street to Southend and Shoeburyness. c2c operates one of the UK's most punctual rail franchises, running intensive services from London Fenchurch Street to Southend and Shoeburyness in Essex. Its driver selection process includes the full OPC psychometric test battery — and the TEA-OCC Test is one of the key assessments that determines whether you will be shortlisted for the role.
Metro operation is arguably the most cognitively demanding regular driving environment in UK rail. Frequent stops, public address obligations, tight headways, and intense passenger activity create a continuous multi-task environment with no recovery periods. The TEA-OCC's combined Part 3 most closely mirrors this operating reality — it is the test most directly relevant to metro and near-metro operations.
The TEA-OCC Test forms part of the OPC (Occupational Personality and Cognitive) battery used across all UK train operating companies, governed by RSSB standard RIS-3751-TOM. The format is identical at c2c as at any other operator — but the stakes are specific to this application.
How the TEA-OCC works
Test format & scoring
TEA-OCC Test
Part of the c2c OPC battery
Three parts: (1) Auditory only — count low tones, ignore high. (2) Visual only — click matching symbol pairs in 45 seconds. (3) Combined — both simultaneously. Your Part 3 score is compared against your Part 1 and 2 baselines to measure divided attention capacity.
What it measures: Divided attention — the ability to process two independent information streams simultaneously without degrading performance on either. One of the most safety-critical cognitive capacities for train drivers.
How to prepare
Preparation tips for c2c candidates
Master each part separately before attempting Part 3
Get the auditory count and the visual scan each to near-automatic before combining them. Part 3 is hard enough without simultaneous novelty.
Let the count run in the background
Most people anchor on the visual task and run the count as a background process. Trying to split attention equally typically degrades both.
Use headphones in a quiet environment
The tone discrimination is harder with background noise. Practise in the same quiet, headphones-on conditions you will have during assessment.
Complete multiple full three-part sessions
The divided attention deficit reduces with practice. Track your Part 3 performance across sessions — it should approach your Part 1/2 baselines.
c2c-specific tip
Run multiple Part 3 repetitions in sequence — metro operation requires sustained divided attention, not just a single successful combined attempt.
FAQ
TEA-OCC Test — common questions
What are the three parts of the TEA-OCC?
Part 1: auditory only — count low tones, ignore high. Part 2: visual only — click matching symbol pairs in 45 seconds. Part 3: both simultaneously. Part 3 is the core divided attention measure.
How is the TEA-OCC scored?
Each part is scored independently. Part 3 performance is compared against your individual Part 1 and Part 2 baselines, measuring how much (or how little) your performance degrades under dual-task conditions.
Is the TEA-OCC in the standard OPC battery?
The TEA-OCC is an additional assessment used by some operators alongside the standard battery. On Train Driver Tests it is included in the premium plan.
Can divided attention actually improve with practice?
Yes. The divided attention deficit reduces as the individual sub-tasks become more automatic, freeing cognitive capacity. Multiple full sessions show measurable improvement in Part 3 relative to baseline.
Is c2c's OPC test the same as other UK train operators?
Yes. The OPC psychometric battery is standardised across all UK train operating companies under RSSB standard RIS-3751-TOM. The Vigilance Test and ATAVT are identical in format and scoring at c2c, Northern, LNER, and every other TOC.
