Donald Trump graduated from the Wharton School at the University of Pennsylvania in 1968, with a Bachelor of Science degree in economics and anthropology. Mensa doesn't accept SAT scores from after 1994. However Mr Trump was a student at Wharton when it was possible to derive an accurate IQ core from known SAT scores. Given the usual requirements for admission to a top school like Wharton, I estimate that Mr. Trump has a 156 IQ at the minimum.
The standard description of this level of intelligence is “Genius – Exception intellectual ability and capable of looking beyond known facts.” However, the percentile rating is more revealing than the raw score. A 156 IQ is at the 99.9905490555 percentile. That means that Donald Trump is smarter than 99.99 percent of the people on planet earth. Not only does Trump qualify for membership in Mensa but he could join the Triple Nine Society.
