ACORN was released to students June 22, 2015.

ACORN stands for Accessible Campus Online Resource Network. For students, ACORN will replace the existing ROSI Student Web Service (SWS). For those unfamiliar with the existing system, it’s where students enrol in courses, check fees and finances and do other records and registration tasks such as making updates to address and contact information.The purpose of ACORN is to provide a more convenient, personalized and guided experience for students using U of T’s online services.

Yes! The ACORN User Experience Design Team works with many students at U of T from various academic backgrounds to help make ACORN and other online tools better. To become a part of the ACORN Student Advisory Team, learn more and sign up on this website if you are interested.

We often hold usability activities in our User Experience Design lab at 215 Huron street. During these 30-45 minute sessions, we invite U of T students to come in and test new designs and features that are in the works. It’s an opportunity for you to see what the ACORN team is currently working on, learn about our UX design process, and it also gives us a chance to meet you and find out how we can improve ACORN to make your student life easier. If you participate in 5 sessions, you’ll also get a credit on your Co-Curricular Record (CCR)!

We do hire work-study students from time to time, and when positions are available you can find them on the Career & Co-Curricular Learning Network (CLNx).

ACORN’s Peak Load Mode is a simplified version of ACORN that is enabled on peak enrolment days to reduce load on the system and improve performance. An example of a peak enrolment day is when priority course enrolment controls are removed for Arts and Science courses in August. The ACORN team will announce these dates ahead of time.

Note: When peak load mode is active, please do not refresh your browser while your course enrolment actions (e.g. enrol, switch section, drop) are in progress, or take the same enrolment actions in multiple browser tabs. ACORN will currently be under peak load, so enrolment actions will take longer than usual to complete, but are in progress even if the system is slow to respond. Refreshing your browser or repeatedly requesting the same action will only slow the system down further and increase the likelihood of your request being rejected entirely.

Why are some of ACORN’s services temporarily disabled?

Due to the high volume of traffic during key enrolment days, the ACORN team has temporarily disabled some ACORN features not essential to course and program enrolment to reduce the load on the system and its supporting infrastructure.

What features and information are disabled or unavailable during peak load periods?

  • Notifications
  • Today’s Timetable on your Dashboard
  • Your invoice
  • Financial awards and aid information
  • Incidental Fee selection
  • Multiple degree invitations, if applicable

Note: All functionality required for course and program enrolment is available.

When will full functionality be restored?

ACORN’s “Peak Load Mode” will only be enabled on isolated high-traffic dates. Regular functionality will be restored within 24 hours.

Please email us at if you have any questions or comments.
