While employers can't generally request SAT scores from the College Board, they can already request candidates to provide them if they want to.

Already seems to be happening but much more upfront. In recent months, I've had two potential employers require I take a "personality" test but only about a quarter of the questions were personality/character attribute based, the rest were clearly intelligence questions, mostly recognizing patterns and testing memory. Tech companies have been pushing the limits of the "directly related to the job" exemption allowed by the Duke Power v Griggs decision for years. Looks like some are ready to simply ignore that court ruling entirely.
