The NPC Web Site has information about starting an alumnae panhellenic.

That said, let me explain what our area does.
We are in a small city of about 50,000. There are only about 2 organized alumnae groups here. About 40 years ago, an energetic couple of ladies started an NPC alumnae Panhellenic here. There were two or three meetings a year as well as the spring tea for high school seniors. Back then, they'd have bridge luncheons to raise money for a scholarship.
Over the years, we've found that nobody plays bridge anymore, nobody wants to meet on weekdays (women work nowadays!) and there are no new Greek alumnae groups forming. BUT - we've kept the tradition of the spring tea.
I'll admit - we are not sanctioned by NPC. We just don't have enough people willing to pay big enough dues to keep the sanction. Our officer elections consist of a few calls saying, "Do you want to do it this year?"
But over the past 25 years, we've kept having the "tea." We put out word through the local newspaper, teen-age babysitters etc. and have a get-together the Sunday afternoon of the local high schools' baccalaureate (everbody is in town!), at 2 p.m. - everybody's still dressed for church. It's at a community room at the local mall. Any sorority that wants to participate can pay the $10 dues and set up a display at the meeting. You can put anything you want on your display and wear anything you want. The only thing we ask is that each group have no more than 3 representatives, in any combination of alumnae or collegians.
At the meeting, we ask the current collegians to talk about recruitment on their campus. We try to have girls with chapter houses, girls with chapter rooms, maybe even a girl from a campus with deferred (January) recruitment.
We talk about how to dress, what to expect, how much it costs, sorority requirements of time and grades...we even cover the "best" sororities and what happens if you don't get a bid.
Each year, we gather between 35 and 50 information forms, with pictures and grade transcripts, on the girls going off to college and sorority recruitment. The president makes up packages for each member group. Our $10 dues are mostly to cover any copying or supplies that she needs to get the packages put together. It doesn't matter if you don't have an organized alumnae group. You can represent your own group as long somebody pays the $10 dues.
It's worked very well for us for a number of years and is MOST helpful to those of us who don't know everybody in town, or don't know kids in that age group!
Yes, we'd like to be an official NPC group, but we just don't have the numbers for it right now.
