Questions people ask
Is there an official TARA raw score conversion?
No. UAT-UK scores TARA using the difficulty of each question you answer, and publishes the scaling constants but no raw-to-score table for any paper, including the specimen and sample.
What is 19/22 in TARA?
Our estimate is 6.6 in Critical Thinking and 7.9 in Problem Solving, from the middle of nine assumptions about how hard the paper is. Across all nine it runs from 4.9 to 8.0 and 6.3 to 9.0.
Why does Problem Solving give a higher score for the same mark?
The two modules have different published scaling constants. In 2026 the same ability level mapped to a higher Problem Solving score than Critical Thinking score. Scores are not comparable across modules.
Are other websites' TARA score converters accurate?
None can be checked: no paper's question difficulties are public and no raw-to-scaled pairs have been released. Ours shows exactly how its estimate is worked out.
How to calculate TARA score?
UAT-UK turns your answers to the 22 questions in each module into a score from 1.0 to 9.0, using a model of how hard each question was, so no fixed mark table exists. Critical Thinking and Problem Solving get separate scores, with no total.

How we work this out
What it does
Turn a practice mark out of 22 into an estimated TARA score, using UAT-UK's published 2026 scaling, with every assumption shown.
A mark out of 22 on one Critical Thinking or Problem Solving paper, taken as practice. The 1.0 to 9.0 scale uses the 2026-entry scaling constants UAT-UK published.
Method
- TARA is scored with a Rasch model: each question has a difficulty, and your ability is the level at which your expected number correct equals your actual mark. UAT-UK then maps ability to the 1 to 9 scale with a published constant and multiplier (Critical Thinking: 2.1055 + 1.9112 x ability; Problem Solving: 3.5686 + 1.852 x ability), capped at 1 and 9.
- No practice paper's question difficulties are published, so we assume nine versions: 22 evenly spread difficulties centred on easier, middling or harder (-0.5, 0 or +0.5) and narrow, typical or wide (spans of 2, 4 or 5 logits).
- We solve each version for your mark and apply the published constants. Our estimate is the middle assumption (centred at 0, span 4), which is also the middle of the nine: Critical Thinking 19/22 gives 6.6, within a range of 4.9 to 8.0.
- The widest range assumes every question sat at the easy or hard edge of the 2026 live questions.
