To be seen as a person with genius IQ, usually someone must achieve a score nearing three standard deviations above the average IQ. Typically a score of 140 to 145 on a test such as the Wechsler would be the cutoff for being termed a genius. However, many tests become unreliable at scores this high, and must be proctored by someone with unique experience and training to make sure the score is measured correctly.
