Which requires them to explicitly ask your age outside the bounds of qualification for a job (over 18 etc). Which ends up opening them to age discrimination lawsuits.
It does not require them to ask about your age, just the year in which you took the SAT. As other commenters have pointed out, this can range from 12 to 17.
Also, they could just ask for your SAT score and any relevant info (if you took it during COVID from your car, etc.) and then you could disclose whatever context you wanted.
