Lewis Terman (1916) developed the original notion of IQ and proposed this scale for classifying IQ scores:
Over 140 - Genius or near genius
120 - 140 - Very superior intelligence
110 - 119 - Superior intelligence
90 - 109 - Normal or average intelligence
80 - 89 - Dullness
70 - 79 - Borderline deficiency
Under 70 - Definite feeble-mindedness
Normal Distribution & IQ Scores
The properties of the normal distribution apply to IQ scores:
50% of IQ scores fall between 90 and 110
70% of IQ scores fall between 85 and 115
95% of IQ scores fall between 70 and 130
99.5% of IQ scores fall between 60 and 140
Low IQ & Mental Retardation
5% of people have an IQ under 70 and this is generally considered as the benchmark for "mental retardation", a condition of limited mental ability in that it produces difficulty in adapting to the demands of life.
Severity of mental retardation can be broken into 4 levels:
50-70 - Mild mental retardation (85%)
35-50 - Moderate mental retardation (10%)
20-35 - Severe mental retardation (4%)
IQ < 20 - Profound mental retardation (1%)
High IQ & Genius IQ
Genius IQ is generally considered to begin around 140 to 145, representing ~.25% of the population (1 in 400). Here's a rough guide:
* 115-124 - Above average (e.g., university students)
* 125-134 - Gifted (e.g., post-graduate students)
* 135-144 - Highly gifted (e.g., intellectuals)
* 145-154 - Genius (e.g., professors)
* 155-164 - Genius (e.g., Nobel Prize winners)
* 165-179 - High genius
* 180-200 - Highest genius
* >200 - "Unmeasurable genius"
More notes on High IQ and Genius IQ:
Einstein was considered to "only" have an IQ of about 160.
Mensa is a society for people with high IQ, in the top 2% (1 in 50).
In 1926, psychologist Catherine Morris Cox published a study "of the most eminent men and women" who had lived between 1450 and 1850 to estimate what their IQs might have been.
A score of 116 or more is considered above average. A score of 130 or higher is considered a high IQ.
If this a a proper iq test, from an actual iq specialist then you are considered the best thing before a genius. Genius is 140.
Yes, that is a very high IQ. A person with an IQ between 90 and 110 is considered average.
Yes, an IQ of 132 is high and you are considered gifted, but if you want, you could try to increase it. IQ is not definite, and maybe you can one day get 169 like me.
I am not sure but the average IQ for any person is 100.
it depends what IQ test you take, but in general, in a modern IQ test 100 is considered average and any thing above 100 is considered above average.
yes. The average IQ is 100. So it means you way past the average mark.
That would be an amazing IQ score for a 6 year old. I am 16 and my IQ is considered high and it is 121.
IQ isn't relative to age. 100 is the precise mean (by definition of IQ) for anyone; the range 95 - 110 could be considered normal. Anything above 125 is quite good.
It's not gifted, but it is considered as Bright Normal Intelligence.
Yes, it is considered high. It would qualify for Mensa.
It is a very high IQ score. It would put you in the top 99 percent of all people.
yes that is really high 121 is considered high intelligents. Mine is 154 yes that is really high 121 is considered high intelligents. Mine is 154
I believe it is, because I think that is how high your IQ has to be in order to be gifted. If it is not a high IQ then it is a very close to gifted average IQ.

225 is a high IQ for an 11 year old. This is the highest known current I.Q. in the world for an 11 year old currently known.
Isaac Newton died long before IQ tests were invented, which makes it hard to put an exact number on his IQ, but when you look at the huge advances he made in both Physics and mathematics, and the typically high IQ of modern theoretical physicists and mathematicians, you would assume that his IQ is quite high. When you are researching Newton, most people put his IQ at about the 170-190 range, which is very high, and with an IQ like that, he is most definitely considered a genius.
An average IQ is 100. An IQ of 120 is high for anyone.
Yes, 133 is a high IQ number
An IQ of 50 is considered low for a human adult. Most humans have an IQ that is between 85 and 100. Anyone with an IQ of 120 or over is considered a genius.
85-99 is a low average a high average is 100-114
If I'm not mistaken, IQ (Intelligence Quotient) is not affected by age, although it is relative to age. 100 is considered the average I.Q. at any age, and 150 borderline genius.
It would be considered average. An IQ of 100 + or - 5% is considered pretty normal.
IQ tests take your age into account so IQ usually does not change as you age. An IQ of 100 is average so an IQ of 117 is considered "bright normal". However remember that IQ tests only measure one area of intelligence: Problem Solving/Logical Reasoning. There are eight areas of intelligence so if you have an average IQ, you can still be considered highly intelligent. Also, IQ tests can be inaccurate. Albert Einstein had an IQ of 160. If you really think about it, it's not that high.
