I know a little bit about Alpha Xi Delta - I am marrying one next month! Anyway, I was trying to help you out but could not find anything about their departure on the school website - although, I didn't have a ton of time to search.
You may want to try:
www.uillinois.edu and search from there.
Best of luck and please post your findings.
TFJ!!

These are both contact points to the Chicago North Shore Alumnae Association, of which the Kappa of Alpha Xi Delta belongs too.
Best of luck!
