Why do some colleges require all testing to be reported?

@Zinhead, DS’s HS didn’t have a photo wall, but word spreads, whether or not a kid wants to advertise it. His 2360 first/single seating was looked up to by the younger kids, IMO more than if he had retaken a few times to get rid of that pesky 1 careless error on the Math section, on a “count on your fingers easy” question.

Fwiw, some kids pushed him to retake, going for a 2400; notably, the HS college counselor and his good friends did not. His response to the trophy seekers was to say, semi jokingly, that he had narrowly dodged the bullet of being the 2400 kid that AOs like to point out as rejected by their college. Privately, he laughed at them, because he preferred spending time with his GF, playing hockey, working at ECs, etc. to getting his name in the local paper.

ETA: he had signed up for the ACT before getting his SAT scores. He did not sit for it, but based on sample tests, might have scored 36. What would the schools he applied to know about his college readiness that they didn’t know based on his SAT?
