What Is an MRABA? The Last Step of Sorority Recruitment, Explained
You've heard "MRABA" (em-RAH-bah) thrown around during sorority recruitment, do you know what it means? Here's what it is, what's in it, what you're signing, and why it exists in the first place.

What MRABA stands for
MRABA stands for Membership Recruitment Acceptance Binding Agreement. The key word is binding. It's a contract between you and the National Panhellenic Conference (NPC), and every NPC sorority follows its terms. That's why the language on the form looks nearly identical no matter what school you're at: it isn't written by your school's Greek Life Office, it's mandated by NPC.
Also called a preference card or bid card: we used to call an MRABA a "pref card" and some schools and outdated campus materials still use "preference card" or "bid card" for this document. Same form, different name.
When you sign it
You sign the MRABA at the end of sorority recruitment, after Preference Round. By that point, you've already had your final conversations with the sorority chapters you're considering and the MRABA is where you make your ranking official.
What's on the form
The MRABA is broken into a few distinct parts. The form itself is sometimes paper, sometimes electronic depending on your school. Either way, it opens with an introduction confirming you're entering a binding contract. Next comes a series of individual statements that you read and initial one by one, confirming you understand exactly what you're agreeing to. After that, there's a section where you rank the sororities you're willing to accept a bid from, in order of preference. Finally, you sign.
What you're agreeing to
Strip away the legal language, and the MRABA comes down to three core commitments. You're willing to accept a bid from any sorority you list. If you receive a bid from a sororoity you listed and decline it, you're locked out of joining any other sorority on that campus for one year, or until the next primary recruitment, whichever comes first. And once you're initiated into an NPC sorority, you can't join a different NPC sorority later, regardless of circumstances.
Here's what that looks like in practice. A PNM who ranks every sorority whose Pref she attended (usually 2 or 3) is guaranteed* to receive a bid from one of them. She will match to her first choice if she is high enough on that chapter's bid list. If her top choice doesn't extend a bid to her, she's bound to accept the bid from her second choice because it was on her MRABA.
How many chapters can you put on an MRABA?
The general rule is to include every chapter where you attended the Pref round, which is usually a max of 2 or 3. As mentioned above, if you include every chapter where you attended Pref, you're guaranteed* a bid. If you were only invited to one Pref round and it's on your MRABA, you will receive a bid from that sorority because you maximized your options.
If a PNM attended 2 or 3 Pref parties but chooses to list only 1 on her MRABA, she loses the guarantee* and it's called Single Intentional Preference, commonly known as a Suicide Bid. Choosing to rank only one chapter on your MRABA when you were invited to Preference with two, is a strategy some PNMs use when they know exactly who they want and they would prefer to take no bid if it's not from their first choice. This is risky, but if the PNM doesn't receive the bid, she is eligible for COB recruiting and can also try formal recruitment again the following year.

Most advice will tell you to maximize your options and "trust the process," meaning don't suicide bid. We think every sorority offers sisterhood, leadership roles, opportunities to try new things, and a sense of belonging, so we're inclined to agree. If you know in your heart you won't be happy at your second choice, we hear you. Just make sure you understand the impact before you sign.
Why this exists
Quota is the maximum number of new members each chapter can invite to join, and that number is calculated based on the number of PNMs who submit MRABAs. The binding nature of the MRABA is what keeps chapter sizes balanced across a campus, and the matching process aims to place as many new members in their first choice sorority as possible.
The COB version of the MRABA: there's a second version of this form that applies in COB. In COB, PNMs sign a separate, shorter MRABA, but only after a bid has already been offered, not before. It's tied to a bid from a specific chapter that's already on the table, so there's no ranking involved, just an acceptance, which makes it a lot less stressful than an MRABA in formal recruitment.
Practical advice before you sign
If anything about the process or the form itself is unclear, ask your Rho Chi before you sign, not after. She can walk you through logistics questions, even if she can't weigh in on your actual rankings.
And know that once you submit your MRABA, that's it. All you can do is wait for your bid.
FAQ
Is the MRABA the same at every school?
The core terms are standardized because it's an NPC contract, not a campus-specific form.
Can I change my ranking after I sign?
No. Once you submit your MRABA, your rankings are final. You can't add, remove, or reorder your choices.
Does signing an MRABA guarantee a bid?
If you maximize your options, yes. If you don't maximize and suicide bid, signing means you'll accept a bid if one is offered from a chapter you listed, but it doesn't guarantee your bid.
What if I change my mind after I get a bid?
If you decline a bid from a chapter you listed on your MRABA, you're not eligible to join another sorority until the next primary recruitment period.
What happens if I don't sign at all?
You're choosing to withdraw from formal recruitment. You won't receive a bid through primary recruitment, but you remain eligible for snap bids and COB if a chapter is recruiting.
Is the MRABA legally enforceable?
It's a binding contract with NPC, and chapters are required to honor it. The consequence isn't a lawsuit, it's the one-year lock-out if you decline a bid in formal recruitment.
The MRABA can feel intimidating because the binding language is intense. But once you understand the structure and what each piece means, you'll see it's important but manageable. Take the ranking seriously, ask questions before you sign, and trust the process.
*We hate to even say this: officially this is guaranteed, but the matching process isn't perfect, and there are extremely rare cases where a PNM lists her maximum options but does not receive a bid. If this happens, she is still eligible for COB recruiting after formal recruitment ends.
