Why do schools offer Spring Admissions? Are they for lower stat kids?

^^^ this…I have seen it happen at BU last year, great kid majoring in Elementary Education but “unhooked” and could not get better than 26 on the ACT (took it like 6 times) and 3.4 GPA, even her private counselor who packaged her well said “you are not getting in” but family was wealthy and she was admitted for Spring 2019.

I know it’s anecdotal, but it makes perfect sense. This is a full pay kid that will pay 300K+ and they liked her background for the major but didn’t want her low 25th percentile stats to adversely impact Fall admit data.
