While I think all three groups Blue Violet mentioned are great, I do want to point out one huge difference between KBG and the other two. Kappa Beta Gamma is only a collegiate sorority. It is just like any NPC group except smaller; it hopes to someday join NPC. ESA and BSPhi, while they do have and want college chapters, are composed mostly of chapters of adult women. This will make a difference in the way the organization is run and in how much experience they have dealing with uniquely college issues. Also, ESA and BSPhi generally don't want to be a part of the local Panhellenic, wheras KBG does. They may rush very differently or be significantly smaller/larger than the NPC groups on campus. KBG will be trying to conform to Panhellenic policies so it is prepared for the day when it must follow them.

Edited to add: In fact, ESA could never be a part of a local Panhellenic, since it practices non-selective membership. Any woman of age can go to their website right now and join with a credit card. I don't mean this as a negative on ESA - I just point this out to show that it is different than NPC groups, and a sorority that hoped to join an NPC org should be aware of the difference.
