I don't really know much about AI as Alpha Ep doesn't have a formal program for it... but, I found this interesting.
On the "Parents" page for a collegiate AOII Chapter:
"
Mothers: Would you like to be a member of AOII?
Membership is available to mothers of AOII's who are not initiated members of another NPC organization. Mothers and daughters have always enjoyed the special closeness of being involved in AOII. You can find an application and more information about our Alumnae Initiate program on our
international web site."
