Cognitive Ability Assessment
The five formats general-ability tests use, with an honest answer about what the number means.
A timed general-ability assessment in the format IQ-style tests use: visual matrices, series, verbal, numerical and deductive logic. Educational and informational. It does not produce an IQ score.

Before you start
- This is an educational assessment. It is not a clinical or psychological instrument, it does not produce an IQ score, and it is not validated for hiring, admissions or any consequential decision.
- Each question shows a suggested time. It is guidance for pacing, not a cut-off: nothing is taken away for going over it.
- Every attempt draws different questions in a different order, so a retake is a fresh test rather than a memory test.
- You can skip a question, but a skipped question scores zero and a considered guess does not.
Your answers save as you go, so you can close this and come back later.
Methodology, limitations and validation status
What it measures. Accuracy across five formats that general-ability tests commonly use: completing visual matrices, extending numeric and letter series, verbal relationships and meaning, quantitative reasoning, and deductive logic. It describes how you handled the items you were shown on this occasion. It does not measure, and does not claim to measure, intelligence as a fixed trait.
Where the items come from. All 50 items in the pool were written for MindScore. The matrices are generated from stated rules, so each key is provably the rule’s own output. None of the items is taken from, adapted from or modelled on a published or proprietary intelligence battery.
How it is scored. Each attempt draws 5 items from each of the five domain pools, in a random order with the options in a random order. Each item scores 0 or 1. A domain score is items correct over items shown in that domain, on a 0–100 scale, and the overall score is the mean of the five domain scores. Fixed thresholds map it to a descriptive band. A percentile is shown only once the comparison group for your device category holds the configured minimum number of valid results.
Validation status. Not independently validated. Item difficulty and discrimination statistics have not yet been collected, no norming sample exists, and no percentile is shown until the minimum sample gate is met.
- This is not an IQ test. An IQ score is a position relative to a large, representative, normed sample, and MindScore does not have one. The result describes accuracy on these items, not a standing in the population.
- 25 items in about twelve minutes is a short sample. Sleep, distraction, the device you used, and familiarity with these item formats all move the result.
- It is not designed or validated for employment selection, academic placement, clinical assessment or any other consequential decision, and it must not be used for one.
- Items differ between attempts by design, so two attempts are not directly comparable item for item, only by domain and overall band.
