  • Research by free online education platform Guru99.com analyzed six different metrics: average IQ, graduation rates, percentage of the population with low literacy rates, average SAT scores, % of the states that don’t have a high school diploma or GED and GDP per capita. These were then given a score out of 10 and combined to give a total score of 60.
  • The Penn Stakes measure of state-level intelligence compiles several intelligence- and education-based metrics: average IQ score; the percentage of a state’s population with a high school diploma, bachelor’s, or advanced degree; and SAT and ACT scores. Higher scores are preferable.
  • 2024 Guru99 data were unavailable for states ranked lower than the top 15 but higher than the bottom 15 (16-35).
