My 7 year old grandson recently was tested for admission into the gifted program in our school system. He was accepted with a score of "3" on the IQ test which corresponds to 98-99%, a "3" in reading at 99%, and a "3" in math at 99.8%. The "3" on the IQ test alone was sufficient for acceptance, but he had the max score possible on the matrix. His WISC-IV results showed a percentage of 99.7% (final--I do not have individual percentages, but all were 99%+). My question is, what IQ corresponds to 99.7%? They just denote 130+.
