There is a persistent scholastic "achievement gap" between races in the US, which jives with fiatmoney's comment: a sufficiently unscrupulous (racist!) employer could use standardized testing as a proxy for racial discrimination. https://en.wikipedia.org/wiki/Achievement_gap_in_the_United_States#Evidence_of_the_racial_achievement_gap:_National_Assessment_of_Educational_Progress_.28United_States.29 https://en.wikipedia.org/wiki/Achievement_gap_in_the_United_... (FWIW, I recently heard the term "opportunity gap" as an alternative to "achievement gap," and I quite like it: it puts the burden on society to improve education, rather than blaming students for "failing" to surmount inequity.)
