The IQLABS IQ test uses 36 matrix-reasoning items that minimize the influence of language knowledge, and scores are calculated from pre-collected age-group norms. Because an online test can be affected by concentration and environment, results are most accurate when you complete it in one sitting in a quiet place.
Raw scores are not used directly; they are converted to a scale with a mean of 100 and a standard deviation of 15 by comparing you with people of the same age. Your result shows both an IQ score and a percentile (top X%), so compare percentiles when looking at other IQ tests.
Borderline intelligence generally refers to cognitive performance in the IQ 70–85 range, between intellectual disability and the average. The IQLABS borderline intelligence screening measures non-verbal reasoning and provides reference information; it is not a medical diagnosis.
Tap ‘Adult Borderline Intelligence Screening’ on the home screen to start right away. After the test, the result page shows your IQ score and percentile together with guidance on whether you fall in the borderline range; a full evaluation by a professional institution is recommended if needed.
The children's intelligence test is scored with separate norms for children aged 12 and under. Results can be distorted if a child cannot concentrate on an online test, so a guardian should guide the child while letting the child choose the answers.
Mensa admission requires the top 2% on an accredited intelligence test. A percentile within the top 2% on IQLABS indicates reasoning ability at that level, but actual Mensa membership is decided only by Mensa's official test.
