The average will always be 100, but how high or low a score is depends on the Standard Deviation (SD) of the test. Most tests use a SD of 15 or 16, but some tests use 24 where a score of 148 would translate to 130 on a test that uses SD 15. There is also no highest IQ possible.Most tests have a maximum possible score you can get on them (For example, the most common professional test in the USA, WAIS, has a maximum possible score of 160 SD 15). However, in theory IQ has no limitation.n I.Q between 90 and 110 is considered average; over 120, superior. Roughly 68% of the population has an IQ between 85 and 115. The average range between 70 and 130, and represents about 95% of the population. A score below 70 may indicate mental retardation, and a score above 130 may indicate intellectual giftedness.
