A range, not a verdict
For example 104–118.
What you get
What the free test reports
Every number comes with the uncertainty around it, because a short test cannot be precise and pretending otherwise would be dishonest.
A score range
A 95% interval on the deviation IQ scale, where 100 is the population average and 15 points is one standard deviation.
A percentile
Roughly where your range sits compared with the general adult population, expressed as a band rather than a single rank.
Question-type strengths
How you performed on pattern, verbal, number and spatial items, so you can see the shape of the result and not just its size.
Inside the test
The four question types
Sixteen items sampled across the reasoning areas that most cognitive batteries cover.
Pattern items. A grid of shapes follows a hidden rule and one cell is missing. You work out the rule and pick the piece that completes it. This is the same family of item covered on our matrix reasoning test page.
Verbal items. Analogies and relationships between words — reasoning about meaning rather than recalling vocabulary. See verbal reasoning for worked examples.
Number items. Sequences and simple quantitative relationships. Arithmetic stays light on purpose; the difficulty is in the structure, not the calculation.
Spatial items. Mental rotation and folding — holding a shape in mind and transforming it.
Being straight with you
What a free test can and cannot do
A short online test is a useful estimate. It is not a diagnosis and it is not an official assessment.
Sixteen questions give a wide interval. That is arithmetic, not modesty: fewer items means less information, and less information means a wider range. If your free result reads 104–118, the honest statement is that your ability most plausibly sits somewhere in that band.
Conditions matter too. Tiredness, interruptions, a small phone screen, or rushing all push a result downward, and familiarity with the format can push it upward. Taking the same test repeatedly inflates scores through practice rather than through improvement.
No online test — ours included — substitutes for a supervised assessment administered by a qualified professional, and none should be used for clinical, educational or employment decisions. Read the detail on our accuracy and limits page.
Going further
If you want a narrower range
The paid full assessment exists for one reason: more information produces a tighter interval.
The full assessment runs 48 questions and adapts as you go — each item is chosen based on how you answered the previous one, so the test spends its questions near your actual ability rather than on items that are far too easy or far too hard. The result is a narrower confidence interval, a reliability figure, a seven-axis profile and a detailed report explaining each part of the score.
The free short test is complete on its own. Take it first, and only pay if you want the precision.
