What Is the Official IQ Scale?

There are many different interpretations of IQ, but the original scale says that above 140 points indicates genius or near-genius intelligence, 120 to 140 implies very superior intelligence, 110 to 119 is superior intelligence and average intelligence lies at 90 to 109 points. On the low end, 80 to 89 points indicates low average intelligence, 70 to 79 points implies borderline deficiency and 69 points and below indicates extremely low intelligence.
