What Mensa IQ test scores are required for admission?
To be admitted, you’ll need a score on the Mensa test that places you in the 98th percentile or higher. Why the 98th percentile? The Mensa test, like the Wechsler Adult Intelligence Scale, Stanford-Binet, and Cattell Culture Fair test all are designed to have scores along a normal bell curve distribution. By design, all of these tests aim to have an average IQ score of 100. So, if you score a 100 you have perfectly average intelligence, regardless of the test you take.
The standard deviation, or variability of IQ scores on these IQ tests do change. But the way the scores are distributed (as in the image below for the Wechsler IQ test) means that 96% of the population will fall between two standard deviations of the mean. So, two be in the top or bottom 2% of the general population in terms of intelligence you would need to be above or below two standard deviations from the mean.
The standard deviations vary based on each test so the following minimum scores are required to be Mensa material between roughly tests), you can be admitted with an official score that places you in the 98th percentile or higher on their scoring scales as well. The Cattell Culture Fair test has a standard deviation of 24. The Stanford-Binet test has a standard deviation of 16. The Wechsler test has a standard deviation of 15. So if you multiply each of these numbers by two and add them to the average score of 100 you’ll get the required minimum scores:
- Cattell Culture Fair – 148
- Stanford-Binet – 132
- Wechsler – 130
