Each year, UA’s Panhellenic Association publishes a guide to sorority recruitment. Here is the link to this year’s edition: http://www.uapanhellenic.com/greek-chic.html. Many other SEC schools will publish similar guides.
For UA, each organization has a threshold high school GPA for prospective new members; and in fact the sorority recruitment registration process requires an official high school transcript. If a prospective new member has less than a 3.0 high school GPA, their options will be very limited as sororities are loathe to accept new members that may represent potential academic risks. In my experience, this is the single factor most likely to determines whether a girl will be invited back to a particular sorority. It doesn’t mean she will not be invited back anywhere, but it dramatically limits her options to join one of the 16 groups that participate in UA formal recruitment. Do not take academics lightly as it relates to sorority recruitment! I can not emphasize this enough. As for recommendations, they are not optional; they are necessary for each of the groups. Start early – in January to secure recommendations which can take a surprisingly long time. Attend Spring Teas in March if possible. Clean up all social media, which is another area that girls think no one is looking at. They look and will release girls with inappropriate, offensive or otherwise negative social media profiles.
