Membership Changes

Wait Lists

Because there are never enough spaces in OSCA to place everyone who wants to become a member, there are wait lists managed by the Membership Secretary. Similar to the OSCA lotteries, placement from the wait lists are made into the highest preferred co-op that has an open spot available. However, unlike the OSCA lotteries, lottery numbers on the wait lists are typically assigned on a first-come, first-served basis. You may change your co-op preferences at any time on the wait lists and your current lottery number will remain unchanged.

You remain on the wait lists until a spot opens in your first-choice co-op or you choose to remove yourself from the wait list. Several times a year we also ask that you verify your desire to remain on the wait lists (it is important that you do so or you may lose your lottery number).

Priority Placement from OSCA Wait Lists

A few people receive priority placement from OSCA wait lists. People who are elected to certain OSCA staff positions for the incoming academic year routinely receive priority placement. In appreciation of all the work they do, every All-OSCA position receives priority placement from the dining wait list. Jobs that require 12+ hours of work per week (usually General Management Team) typically receive priority placement from the housing wait list (housing placement includes dining).

To learn how you too can become a part of the All-OSCA staff and receive priority placement from the wait lists, check out the Staff section.


Each April, OSCA holds an Upperclass Lottery to determine who will become members of OSCA the subsequent Fall. All participants in the UC Lottery receive a randomly assigned lottery number. Applicants who are notified that they have been assigned to OSCA during the UC Lottery must turn in a deposit to guarantee their spot in the Fall; this includes students currently on Leave of Absence who are participating in the Upperclass Lottery.

Each June, OSCA holds a New Student Lottery to fill the 100 spots we reserve for first-years. As with the UC Lottery, all participants receive a randomly assigned lottery number. No deposit is required of first-years joining OSCA.

Special Interest Co-ops

There is a special application process to join our special interest co-ops: Third World Co-op, Third World Social Justice Co-op, and Old Barrows Co-op.

Third World Co-op (TWC) exists to promote coalition building through dialogue among people of different racial, cultural, ethnic, and socio-economic backgrounds who have been traditionally disenfranchised.

Third World Social Justice Co-op (TWSJ)

Old Barrows Co-op (Old B) is a housing-only co-op that functions to provide a housing community for those who feel oppressed by their gender. Old B is primarily focused on the inclusion of trans and non-binary individuals with a secondary emphasis on cisgender women.

People who wish to become a member of TWC, TWSJ or Old B are encourage to submit an application, which will be reviewed by current relevant selection committees.

Your Co-op Membership Agreement

You accept your spot in OSCA by submitting your signed dining contract, housing contract (if relevant), and OSCA deposit to the OSCA Office and OSCA Financial Office, Wilder 402 and 406 respectively. These forms will be due to the OSCA Office on the first Friday of the spring semester at 4:00 pm.

**For the 2022/23 school year, dining/housing contracts and deposits will be due on February 25th, 2022 at 4:00 pm to the OSCA Office, Wilder 406. 

If your plans change, you may be released from OSCA until July 10th. After this date, you will be held liable for your OSCA bill for the coming year: for dining members, this is a semester-long commitment; for housing members, a year-long commitment. 

If you want to be released from your OSCA dining or housing contract, please email the OSCA account at
