Continuous Open Bidding (COB)
Continuous Open Bidding (COB) is an informal recruitment process that allows eligible Panhellenic sororities to extend membership invitations outside of the primary recruitment period. COB provides an additional opportunity for students to explore sorority membership and connect with chapters that may have openings.

Things to Know About Continuous Open Bidding (COB)
Eligibility
All full-time students are eligible to participate, provided they have not been initiated into a Panhellenic sorority.
Students must not have completed the Membership Recruitment Acceptance Binding Agreement (MRABA) during 2026 Formal Panhellenic Recruitment.
What to Expect
Chapters may reach out to interested students to invite them to events, provide information about their organization, or offer membership.
Each chapter has its own approach to COB, so opportunities and experiences will vary.
Submitting the COB Interest Form does not guarantee contact from a chapter or an invitation to join.
Understanding the Process
COB is managed by individual chapters rather than through a formalized, centralized recruitment process.
Chapters will determine their own approach to connecting with interested students and extending membership invitations.
Completing the interest form allows participating chapters to receive your information and connect with you about potential membership opportunities.
Complete the Continuous Open Bidding Interest Form to share your interest in joining a sorority. Your information will be shared with Panhellenic chapters that are participating in COB so they can connect with interested students and provide information about their membership opportunities.
Submitting the form does not guarantee an invitation to join a chapter. Opportunities vary by chapter and depend on membership availability.
