Objective rankings

LMAO that's called 'selectivity'. Maybe that's a big word for you, you can look it up. Also higher GPA is directly correlated to higher retention. You can look up 'correlated' and 'retention' too.

I want to reply to the comment below. The others could be selective based on other factors, not necessarily academics but more superficial characteristics. I am not sure GPA is “directly” correlated either, but high performers in academics tend to be more involved. If you can show the information about retention rates I’d be interested to see that too

Well good for you, but there are plenty of pnm's who do care about chapter GPA because they want an indication of which sororities value academics and will help support their members in that respect. STEM majors and those that intend to go to grad school especially get kind of worried that sorority membership will be too time-consuming and that the social aspect will be too big of a distraction; they want to keep their grades up.

If the sisterhood isn't understanding of members with certain academic goals then it's not the right fit. Recruitment is when a pnm can ask questions and see what the culture is like in a chapter's membership and the various majors in the chapter too; GPA just gives the first look. If you don't care about a chapter's GPA then there's certainly a house like that for you.

Don't assume that higher GPA chapters don't have close sisterhoods.
