TARA raw score calculator
Turn a practice mark out of 22 into the range of TARA scores it could represent, using UAT-UK's published 2026 scaling, with every assumption shown.

One mark out of 22 has no single TARA score: it depends on how hard the paper was, which is never published. We show the range first.

What it covers
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 (Tables 2 and 3).

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. The range is the lowest to highest of the nine. The middle assumption (centred at 0, span 4) gives the single middle figure, for example Critical Thinking 19/22 gives 6.6, within 4.9 to 8.0.
- The widest range assumes every question sat at the easy or hard edge of the 2026 live questions (difficulties between -3 and 3, Tables 22 and 23).
Uncertainty and limits
- The nine versions are illustrative assumptions, not measured papers. The range is not a 95% confidence interval.
- There are no published pairs of raw marks and scaled scores, so this has never been checked against real results.
- The scale is set again after each cycle's October sitting, so the 2027-entry scale may differ from 2026's.
- UAT-UK does not publish how it scores 0 or 22 out of 22, so we give no figure for those.

What the answer means
The answer says which part of the 1 to 9 scale a practice mark is consistent with, and how much that depends on the paper. It is not an official conversion, a percentile, or a prediction of your real TARA score. UAT-UK publishes no raw-to-score table.
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?
Somewhere from 4.9 to 8.0 in Critical Thinking and 6.3 to 9.0 in Problem Solving, across nine assumptions about the paper. The middle assumption gives 6.6 and 7.9. Treat the range as the answer.
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. A converter that gives one number without a range is hiding that uncertainty.
