Commencement will take place on Friday, May 31st, and there is a website for detailed information about the ceremony here; at the moment, that page has information about last year's ceremony and that will be updated as the year passes.
There are some rules about who can participate. Seniors who are close to completing their degrees may participate in the Commencement ceremony even though they will not actually receive their diplomas on the day of Commencement. Seniors who have completed eight semesters must be within two units or two requirements of completing their degrees in order to march at Commencement. Seniors who have completed only seven semesters and so are eligible to return to Wellesley for another semester may march as long as they are of diploma-grade standing. If you anticipate that you will be in either of these categories, please see your dean as soon as possible to discuss your plans. Please also let them know if you will be completing your degree in December or if you will be returning for your eighth semester in the fall and prefer to wait until the next Commencement.
