The Evening MBA Association (MBAA) is a student government organization created to support the Evening MBA student community. It is run by peer-elected Foster Evening MBA students who have a mission to create inclusive opportunities for evening students to connect, build lifelong friendships, and experience the collective Foster and Greater Seattle Area business communities.

The Evening MBAA facilitates activities for community building and professional development while working directly with the MBA Program Office and administration, striving for continuous program improvement. The Evening MBAA also partners with the Full-Time MBAA to plan cross-program events, manage their shared student organizations, and enhance the student experience for all Foster MBA students.
