Advice for PNMs: Not getting a bid to your 1st choice.

Bid matching is, effectively, a multiple objective problem, because you want to maximize PNM happiness across all PNM's and chapter happiness across all chapters. That means there has to be a trade-off somewhere, and the one chosen, for whatever historical reason, is that the chapters' preferences trump the PNMs' preferences.

So, in my prior example, I was incorrect. If quota is 10, and Polly PNM is 11, and Suzie PNM is 12 on the bid list, the spot will go to Polly over Suzie, even though this group is Suzie's first choice and Polly's 3rd. So Suzie gains nothing by listing this chapter as her #1, and Polly loses nothing by ranking them 3rd.

Exactly. In the end, the chapter gets the final say unless as long as their choices want them. The end result, if you asked the chapter, may not be so optimal. Would you really want Polly who put you 3rd over Suzie who put you #1? I probably wouldn't. But...that's how it works. Residency Match works essentially the same way, but no one questions the match, they just put in their picks and shows up on match day. If you don't match, you scramble for a leftover spot. That's sorta the equivalent of Snap bidding, I guess!

I'll just keep the off-topic stuff going...I always thought it would be interesting if chapters could have "A-lists" and "B-lists" every round. If a chapter is, for example, supposed to have 100 women at the first invitational round, and they historically have a 50% return rate, they'd get to issue 200 invitations, and have, say, 10 on the "B-list". The computer would do the first round of scheduling as normal, and if the chapter had fewer than 90 women, any women on the B-list who didn't have full schedules would then be added.

It would be a way for chapters to take a second look at a PNM who hadn't been their first choice, much the same way we encourage PNM's to take a second look at a chapter they ranked lower.

They sorta do that with the Flex List. The only problem is that I've seen chapters look at these women as "cut." It's like the ranking that PNMs do. It's hard to get PNMs to look at chapters that they "cut" when they turn up on their list again. From first hand experience, these women can be treated as leftovers or rejects in ways that Snap bids or other ways of maximizing aren't because the whole chapter isn't involved in that process. There would need to be a big PR push or way of doing it that made it not seem like these were women who are released who can be brought back if the chapter doesn't hit their return number.

Which is why a chapter is never required to provide a plus list. The women on the plus list should only be women for which the chapter says "gee I'm sorry that we have to cut Suzie Q and Polly PNM and Nancy NicePNM" and not oh my .. why did we invite back the Wicked Witch of the West?

Really? That wasn't explained to the chapter in question...or at least the adviser didn't want them to know. That led to problems later. Good to know.

Here's the link to NPC's current report on RFM

https://www.npcwomen.org/resources/p...ate%202010.pdf

it talks about flex lists on the second page.

Thanks! It makes total sense when I stopped to think about it. You can't make a chapter take back women they don't want, but if they're smart, they'll build it into their MS system.

I know people on here have talked about their GA/Panhellenic "forcing" them to provide flex lists or invite a certain number of PNMs back. If your school has a history of this, that's when you get your national peeps in on things before rush and tell them "the GA wants us to invite Paris Hilton's brain on Jabba the Hutt's body. Please tell them to go pound sand."

Yeah, but I don't doubt that's also been used by a chapter advisor as a convenient excuse. I'm not saying that a chapter should invite anyone and everyone to make quota, but I know that I may not have made the best decisions as an 18-year-old collegiate.

You owe me a new monitor. There is now water all over this one.

I don't understand this whole flex list thing, but I can't believe a chapter would be forced to invite back Lizzie Borden the Ax Murderer with the 0.1 GPA, even if this means they don't make quota.

And that's exactly what the flex lists in RFM are... if a chapter doesn't do as well as historically then they will take PNMs from the plus flex list and issue more invitations... if a chapter does better than historically, then they won't invite PNMs from the minus flex list.

The flex lists happen every round? Shows you how out-of-date I am. I thought they were just used at the end, if bid lists were turned in before the number for quota is set.

With RFM, flex lists are asked for for every round. Minus lists are required to be provided, plus lists are not. Although, if a chapter is continually inviting all PNMs left in their pool, plus lists are kind of irrelevant.
