CA mom- it depends upon the school and how recruitment is done. if she had three choices chances are good that she will get one of her choices. Some schools have something called guaranteed bidding where if a PNM has gone through and attended all parties they are guaranteed a bid. However, not all schools do have this, please know the goal is to place /match as many women as possible during recruitment.
A suggestion would be for your daughter to speak with her Rho chi (recruitment counselor) about her concerns because she will be best equipped to respond based upon the schools'/panhellenic guidelines. Again, please remember the goal is to place as many women as possible.
Best wishes to your daughter, I look forward to hearing where she pledges! Please let us know.
with smiles
Merry
