What is the highest score a person can get on an IQ test? What is the average score?

Answer 1

Different tests yield different scores. One person may score 140 on one test, and 185 on another. Some tests have a maximum score of 150, others of 200.

Also, as you get older, your IQ technically goes down. This is not because you get dumber, but because IQ tests are measured against a comparative sample of people the same age as you. If you answer the same number of questions correctly at 18 as you do at 24, you will be given a lower IQ.

Answer 2

Well, that's kind of an open ended question (about the highest score). It all depends on the test. Some tests have a ceiling of 140, others of 160, and some are specifically designed to be as accurate as possible in measuring score in the highest ranges - up to 200. However, statistics tells us that the probability of getting an IQ score of 200 is 1 in about 120 billion! There simply aren't enough people in the world to make this score a viable option. Thus, the highest score most people consider achievable is about 195. As mentioned earlier, a special test is required for that - like Raven's Advanced Progressive Matrices. The average IQ score is 100. That's what 50% of people get. Here's a general guideline for interpreting IQ scores:

140+ Extraordinary intelligence
130-140 Very superior intelligence
120-130 Superior intelligence
110-120 High average intelligence
90-110 Average intelligence
80-90 Below average intelligence
70-80 Borderline deficiency
Below 70 Intellectually challenged

Answer 3

A person can only get the top score or ceiling of an IQ test as designed by the psychometrician. You might wonder why you have a discrepancy in your IQ scores from one test or website to another. Don't worry, this is because test makers have set a certain ceiling for their tests. For example, in one test you might only get a 125 and in another a 136, it is because the ceilings or top scores are different. There is no big variation in your scores in the range of normal (100) to above average (120-130) but as you take harder tests, your score might climb. The idea is to take more tests and harder tests to assess what your estimated IQ is. However, special tests should be taken when your IQ is 140+ since at higher levels, tests for normal distribution and above average are usually inaccurate. Likewise, when you take Power IQ Tests like Mensa, you may have a high score and in another difficult test, a lower score. This is not surprising. There is a percentage or degree that you may pass one and fail in another for a passing criteria.

Average IQ scores will usually be 90-100.

Eysenck Tests many years ago have a ceiling of about 130-135. Nowadays, one could go 20 points up because of better testing methods on IQ measurement.

There are many factors that affect one's score. English tests put the non-native speaker at a disadvantage and often times, your score should be adjusted to +10 points to reflect your IQ in proper comparison with native speakers.

Answer 4

The highest possible score depends on the test itself. In theory, IQ has no upper limit. However, each test has a specified 'ceiling' score, that is the score you get by answered every question correctly.

In order to raise the ceiling you make the test harder, but testing IQ beyond 160 is all around very unscientific and not much is known about it and how reliably it can be tested.

Even high range tests, like Ravens APM or the Binet adult scale, Cattel high range scale...cannot properly test high range IQ. At best they can reach a level of 160.

Answer 5

There is a wide range of scores with IQ tests. The scoring goes like this:

less than 70 - feebleminded
70-79 borderline intelligence
80-89 dull
90-109 normal or average
110-119 superior intelligence
120-140 very superior intelligence
over 140 genius

At the low levels like between 10 and 70 are the more severe impaired like the idiots and imbeciles.

Beyond 140 upwards to 200 and beyond are higher levels of intelligence , called super geniuses.

Answer 6

For a more serious measurement you should consider taking Paul Cooijman's tests. His tests are widely accepted in the high IQ community. I am one of his highest scoring testees. I scored IQ 177 (16SD) on LIMIT, which is the highest recorded score on that test. Childhood scores are not comparable with adult deviation IQ's. I am age 20.

Answer 7

I dont know but 2 of my friends scored 200+ and one scored HIGHER

Answer 8

I've heard of people with 270 but they're usually incapable of surviving real life because they're too smart.
