The exact classification of an IQ score depends on which test was administered, but in general, a score of 135 would mean that the person was of significantly above average intelligence. An average IQ score generally falls within the range of 85 to 115.
IQ stands for "intelligence quotient," and there have been many different types of IQ tests used over the years. The vast majority of the tests consider any score over 130 to indicate superior intelligence, but some tests make a distinction between this level and the genius level, which begins at 140. Most tests do not separate scores past the 130 level into different classifications, as scores this high are extremely rare.
