The Davidson Institute was featured in this Psychology Today article: Gifted Children: Nurturing Genius (Part One)
“As such, Davidson programs for the gifted serve what they refer to as profoundly gifted youth. They define that with tests that are 99.9% or higher or children that are 3 standard deviations above the norm. Depending on the IQ test, children participating in Davidson programs may norm differently and can peak anywhere from 145 to 150 in terms of IQ. The problem, as addressed in Genius Denied, is that ‘while children of IQs of 120 to 160 may be called gifted, they learn at different rates and think at very different levels.'”
