Declining to Participate in Formal Recruitment

[LadyLonghorn]

1) Is participating in formal recruitment a requirement for NPC sororities?
No

2) Can a chapter opt out of formal recruitment if they find that the COB process works better for them? (Assuming they will not be penalized for a smaller pledge class than the rest of the chapters on campus)
Yes, this is the case here. One of the chapters lost their house a few years back due to declining numbers and then decided to not participate in FR any longer. I don't know the story beyond that.

3) On your campuses, would/do/have Jewish sororities found it more beneficial to have a COB process than formal recruitment?
In our case, yes, it was one of the two historically Jewish sororities here. I have no idea what their numbers are like now.
