An 'average IQ score' or 'normal IQ score' can be defined as a score between 85 and 115. The Mensa qualifying IQ score is a score that puts you in the top 2% of the population in a bell curve like this one. The Mensa qualifying score is 130 or higher, as shown below.
In this regard, what is considered a high IQ Mensa?
The scores above 115 are generally considered as “high IQ,” and those above 130 to 132 (depending on the test taken) are usually considered highly gifted and are in the top 2 percent of the population. This level also qualifies you for membership in American Mensa.
What is the IQ of the top 2 percent?
“Average” is 100. It splits the population right down the middle: the odds a person will have an IQ of 100 or higher are 1 in 2. To qualify for membership in Mensa, your IQ needs to be in the top 2 percent—around 130 or higher. It's the top 2 percent and not the top 1 percent due to, of all things, a math error.
