An IQ score over 140 indicates that you're a genius or nearly a genius, while 120 - 140 is classed as "very superior intelligence". 110 - 119 is "superior intelligence", while 90 - 109 is "normal or average intelligence".
The maximum IQ score assigned by the WAIS-IV, a commonly-used test today, is 160. A score of 135 or above puts a person in the 99th percentile of the population. News articles often put Einstein's IQ at 160, though it's unclear what that estimate is based upon.
85 to 114: Average intelligence. 115 to 129: Above average or bright. 130 to 144: Moderately gifted. 145 to 159: Highly gifted.
A score of 116 or more is considered above average. A score of 130 or higher signals a high IQ. Membership in Mensa, the High IQ society, includes people who score in the top 2 percent, which is usually 132 or higher.
Notably, the average IQ score falls between 85 and 115. A score above 140, meanwhile, is considered to be genius level.
Mensa's requirement for membership is a score at or above the 98th percentile on certain standardised IQ or other approved intelligence tests, such as the Stanford–Binet Intelligence Scales. The minimum accepted score on the Stanford–Binet is 132, while for the Cattell it is 148.
IQ tests are made to have an average score of 100. Psychologists revise the test every few years in order to maintain 100 as the average. Most people (about 68 percent) have an IQ between 85 and 115. Only a small fraction of people have a very low IQ (below 70) or a very high IQ (above 130).

Mental age, intelligence test score, expressed as the chronological age for which a given level of performance is average or typical. An individual's mental age is then divided by his chronological age and multiplied by 100, yielding an intelligence quotient (IQ).
There is no other qualification for initial membership eligibility. Generally, there are two ways to prove that you qualify for Mensa: either take a test administered by Mensa, or submit a qualifying test score from another approved test. There are a large number of intelligence tests that are 'approved'.
Historically, IQ was a score obtained by dividing a person's mental age score, obtained by administering an intelligence test, by the person's chronological age, both expressed in terms of years and months. The resulting fraction (quotient) is multiplied by 100 to obtain the IQ score.
