CBAT Test: What It Is, How It Is Scored and How to Practise
CBAT stands for Computer Based Aptitude Test — the RDSO-designed aptitude stage of Railway Recruitment Board selection. Unlike CBT-1 and CBT-2, there is nothing to revise from a textbook. The CBAT tests trainable skills: working memory, precision with instructions, depth judgement, sustained concentration and raw perceptual speed.
CBAT vs CBT-1 vs CBT-2
The three stages test completely different things, which is why preparation strategy cannot be shared between them.
| Stage | Nature | What it covers | Marking |
|---|---|---|---|
| CBT-1 | Knowledge test | Maths, general intelligence and reasoning, general science, general awareness | Negative marking applies |
| CBT-2 | Knowledge test | Part A general subjects plus Part B trade-specific technical questions | Negative marking applies |
| CBAT | Aptitude test | Five RDSO batteries: memory, following directions, depth perception, observation, perceptual speed | No negative marking; T-score of 42 needed in each battery |
The five batteries of the CBAT test
- Memory — recall track maps, word lists and signal sets after a timed study screen.
- Following Directions — execute multi-step written instructions exactly as written.
- Depth Perception — judge hidden volume and three-dimensional structure.
- Power of Observation — the biggest battery at 75 questions; find a target among near-identical items.
- Perceptual Speed — compare symbols, letters and dials quickly without slipping on accuracy.
How the CBAT is scored
Raw marks are standardised into T-scores so batteries of different difficulty can be compared fairly. The qualifying bar is a T-score of 42 in each of the five batteries, and there is no aggregate to trade against — one battery below 42 ends the attempt. There is no negative marking, so every question deserves an answer.
Practising the CBAT test properly
Practise full sessions, not fragments. The Exam Room's 235-question mocks run on a replica of the official console — sectional timers, the five-colour question palette, study screens and battery-wise T-score results — so exam day holds no interface surprises. Two mocks are free; the remaining pack is a one-time purchase with lifetime access.
CBAT test FAQs
What is the CBAT test?
CBAT stands for Computer Based Aptitude Test. It is the RDSO-designed aptitude stage of Railway Recruitment Board selection, used mainly for Assistant Loco Pilot posts, and it measures memory, following directions, depth perception, concentration and perceptual speed.
Who has to take the CBAT?
Candidates shortlisted after CBT-1 and CBT-2 in ALP recruitment take the CBAT. Aptitude testing has also been used for motorman and other running and safety-category railway posts.
How many questions and how much time does the CBAT have?
A full-length CBAT session has 235 questions and runs about 61 minutes, with each of the five batteries separately timed.
What is a good CBAT score?
Scores are reported as T-scores, not raw marks. The qualifying bar is a T-score of 42 in every battery; a balanced profile above that in all five batteries is far better than a high average with one weak battery.
Can I prepare for the CBAT test in Hindi?
Yes. Every question, instruction screen and result page on The Exam Room is bilingual, so you can practise in English or Hindi and switch at any time.
