Bentley College restricted recruitment in the Fall of 05. Basically, once school started, the Greek Council and GA decided that no one could rush (men and women) so that they could take a look at Greek life and make it better. It was a joke, nothing changed. Also none of the groups involved their alumnae or advisers in the decision, so I alone was fighting all the Greeks who had been brainwashed into thinking this was ok (at one point in an auditorium with every Greek on campus, doing my best to remind them all of the green book, which no one, including the GA, seemed to be aware of), all while I was pregnant and extremely nauseous. It wasn't fun.
Basically the school, which is private, was able to get away with it. We didn't have an NPC delegate at the time for some reason, and even though I tried to contact them, the other national groups, no one cared besides my own group.
So I guess I'm saying that yes it can happen. I hope it doesn't to your school though. We had women who were interested as juniors who ended up not going through in the spring because they felt it was too late. I thought that was really sad. The one benefit was that it allowed us time to really work on other areas of the chapter.
