07/15/2018 7:00 am. The WASS system has been replaced by the WASE system, available at: https://wase.princeton.edu. If you used WASS to schedule appointments this past academic year, then your WASS calendar will have been migrated to WASE. If you have published URL links to your WASS calendar, you should update these to point to WASE. Please contact the OIT help desk if you have any questions.
