This has links to the sororities at SWT. On the ZTA page, it says you can contact Lindsey Roberts for Spring 2002 recruitment information:
LinzR0588@aol.com.
It appears that SWT does hold a formal recruitment in the Fall and informal recruitment (C.O.B) in the spring. As I mentioned earlier, not all chapters will participate in Spring recruitment. It may be that all chapters will be at total and no chapter is eligible for spring recruitment. In that case, you would have to wait until Fall recruitment to join a sorority.
There are 7 NPC sororities on the SWT campus, 3 Multicultural sororities and 3 NPHC sororities.
Good luck!
