Digital Guide
The COB Playbook
14 pages on continuous open bidding, the recruitment path almost nobody talks about.
Continuous open bidding is the less obvious way into a sorority. Everything you've seen on RushTok? That's not this. There’s no rounds, no cuts, no running across a lawn to a hundred screaming girls. There’s coffee, there’s ice cream, there’s you and a chapter deciding if there's a mutual fit. Most girls who’d be perfect for COB never even find out it exists, or they find out too late.
I know, because COB is how I joined my sorority. Then I spent the next decade on the other side of recruitment, 40+ as an advisor, watching this process from behind the scenes. This guide covers how COB actually works, start to finish. When it opens, how to get started, the exact messages to send, what to expect at every step, and the one document you need to understand before you sign anything.

Who This Is For
If you skipped formal, or you’re not sure sorority life is even for you, this is for you.
Most people have no idea COB exists, let alone how to navigate it. Maybe you decided formal recruitment wasn’t for you and thought that closed the door. Maybe there’s really only one chapter on campus you’d want, and meeting all of them sounds exhausting. Maybe you listed only one chapter on pref night (intentional single preferencing), didn’t get matched to a bid, and now you’re deciding what’s next.
This guide is for the girl who wants a real plan for continuous open bidding instead of guessing. It’s built for anyone who connects better in small groups with deeper conversations. If you want to know exactly how this path into a sorority works, this is the guide.
What Makes This Different
There is almost no information out there about COB, let alone good information. This is the whole map.
Search continuous open bidding and you’ll find a couple of vague paragraphs and a lot of nothing. No one explains when it starts or what to expect. And a lot of girls just don’t even know this process exists.
This guide is from the other side of the process, and it’s personal. I joined my chapter through COB myself. Then I spent 40+ recruitments in the basement watching how chapters actually run all aspects of recruitment, who they invite, and how the timing really works. I’m not handing you vague encouragement. I’m handing you the timeline, the scripts, the strategy, and everything you need to try COB.
Frequently Asked Questions
What you’re probably wondering before you buy.
What is continuous open bidding (COB)?
COB is how sororities fill their open spots after formal recruitment ends. Chapters that come out of formal below total (the chapter size Panhellenic wants them to reach) have room, and COB is the official process of filling those spots. Unlike formal, you don’t meet every chapter. You might meet just one or two. This guide covers the whole process.
When does COB start?
For you as a PNM, depending on the semester COB starts on Bid Day or the first day of classes. How long it lasts depends on the chapter. The guide breaks down the real timeline, including a move that gets you on a chapter’s radar months before spots even open.
Do I have to go through formal recruitment to COB?
No. You never have to go through formal to get a COB bid. That’s the key difference between COB and snap bidding (a bid extended right after formal by chapters that didn’t fill all their spots), and the guide explains both so you know exactly which path applies to you.
Is COB a backup plan or a downgrade?
No. Getting a bid into a sorority is getting a bid. Period. COB can get you a bid. Plenty of women join through COB not because formal went wrong, but because they never wanted to do formal in the first place.
