Scoring
How the CBAT T-Score Works and What Actually Qualifies You
6 min read
Most CBAT confusion comes from one sentence in the result: candidates are evaluated on T-scores, not marks. Understanding this changes how you practise.
What a T-score is
A T-score is a standardised score. It places your raw performance on a common scale so that a battery of 75 easy questions and a battery of 40 hard ones can be compared fairly. The scale is centred around 50, with most candidates falling between roughly 30 and 70.
The practical consequence: raising your raw score in a battery where everyone scores well moves your T-score only slightly, while gaining a few marks in a battery where most candidates struggle can move it a lot.
The 42 rule
- Each of the five batteries is scored separately and converted to a T-score.
- You must reach at least 42 in every battery.
- Falling below 42 in even one battery ends your CBAT, regardless of the other four.
There is no aggregate, no best-of-four and no compensation between batteries. Treat the CBAT as five separate pass/fail tests taken back to back.
Reading your mock result
A useful mock gives you five T-scores, not one percentage. When you review a result, work down this list:
- Which batteries are below 42? Those are the only ones that matter this week.
- Where did you leave questions unattempted? With no negative marking, a blank is strictly worse than a guess.
- Where was your accuracy high but attempt count low? That is a pacing problem, not a knowledge problem.
- Where was your attempt count high but accuracy low? Slow down deliberately — rushing costs more than it earns.
A realistic target
Aim to sit comfortably above the bar rather than exactly on it. If your weakest battery hovers around 45 to 50 across several full-length mocks, you have a genuine margin for a bad exam-day screen or a distracting test centre.
