Are there any widespread test given in schools that are proxy IQ tests? Mensa accepts older ACT and SAT scores as they consider the current versions to be knowledge tests but older versions to be intelligence tests. Not sure if this is still the case but at one time all high school students in the State of New York were required to take the SAT prior to graduation. While not representative of the entire population, it would have been a good representation of the high school student slice of the population across the entire state. Perhaps that would have been good enough for some uses.
