question

Your daughter should make friends, make good grades and keep a good reputation this year. She could go through rush again as a soph and if she has made some VERY good friends in a certain house or in a few houses and she has great grades and a great reputation, she MIGHT get a second chance.
When I was in a sorority at Alabama we had two spots during rush for sophomores. Most often those spots went to a girl who was already good friends with some girls in the house but had gone to a different college Freshman year and did not go through rush at that college. They had good grades, good reputations and already had friends in the house.

needs to get active on campus to meet and befriend sorority members - most are very active in organizations and churches on and off campus. She also needs to make the very best grades possible.

Thank you so much for your help. What about the open bidding? How does that work? And what are the chances with that?

If any sororities are doing COB, there could be a chance of getting a bid, especially second semester after girls have graduated, transferred or resigned. COB is nothing like formal recruitment. Once you sign up, a sorority member might call to invite you to lunch, or to an apartment or dorm room to watch a movie with friends, or go out for coffee.
Sometimes sororities sign up for COB but only have a couple of spots to fill and they already know who they want, so she may never hear from them.

There is no formal bid day. Another call or a visit from a sorority member handing them their bid - that's it.

I don't think it costs anything to sign up for COB. She can try it and if nothing happens, sign up for formal recruitment next fall. In the meantime: 1. grades 2. involvement 3. good reputation.

Good luck to her - I was a COB pledge!
