What is the highest Intelligence Quotient possible?

Answer 1

Well, no one knows who has the highest IQ in the world-for all you know, it could be me. But the highest IQ on record is that of child prodigy and physicist Kim Ung-yong, whose IQ was measured at 210.

This does not, however, mean that he is the most intelligent person to have ever taken an intelligence quotient test. These tests are made to measure intelligence with the most accurate means available, and they are by no means flawless.

It is also important to realize that the score one receives on an IQ test varies depending on the test, and the same person may score differently on the Wechsler Test versus the Stanford-Binet Test yet still have the same quotient of intelligence.

Answer 2

Normally there is no such limit. But for adults the maximum is taken as 200 and anything above is Unmeasurable Genius although the max recorded is 228 and for kids it is 250.

Answer 3

The highest Intelligence Quotient (IQ) possible is typically considered to be around 200. Scores higher than that are rare and not reliably measurable due to limitations of the IQ testing scales.
