New Triton Student System (TSS): What Parents and Families Should Know

Dear Triton Parents and Families, 

UC San Diego is preparing to launch the Triton Student System (TSS) in July 2026. TSS will replace MyTritonLink and become the university’s new system for key student services such as course enrollment (now called booking in TSS), the Schedule of Classes and student financial information. The purpose of this transition is to modernize our aging infrastructure as part of a larger technology renewal effort. For more information, check out our project vision. 

To support you and your student during this transition, this message covers: 

• What parents and families should expect
• What's changing for students
• Key dates
• How you can support your student
• Where students can get help

We know you play an important role in helping your student navigate their academic journey. We encourage you to review this information and check in with your student about information that may impact their experience. 

This transition is designed to be gradual, and UC San Diego is planning communications carefully to reduce confusion and disruption.

Parents and families may notice:

• Increased messaging to students in the weeks leading up to the TSS launch in July.
• A period of adjustment during July and August as the university stabilizes processes and support.

During this time, students may have questions about how to complete tasks in the new system (TSS). UC San Diego will provide support resources to help them navigate changes.

What's Changing:

Where students enroll, view their schedule, final grades, academic history, financial aid, account balance and more.

What's Changing:

Your student's ID number

*Students will use their TSN in TSS; some students may see their TSN earlier in financial aid and annulment systems
*There will be no need to receive new  Campus ID Cards. ID cards printed with the legacy PID will remain valid and do not need to be replaced. New printed cards will have TSN.

What's Changing:

What we call signing up, choosing, or registering for classes.

What's Changing:

The format for major and course codes

*Review the list of undergraduate major codes and what they’re changing to.

May – June 2026:

• Summer Session enrollment will be managed in the existing student system via WebReg. 
• Housing dates and deadlines for undergraduate and graduate and family housing may differ this year.
• Financial Aid deadlines are listed below. For more information visit: Financial Aid & Scholarships.

  • Incoming students are required to submit documentation for financial aid before June 15, 2026.
  • Continuing students were required to submit financial aid documentation by May 1, 2026.

July 2026: TSS launches 

• Expected mid-July: Students access TSS for the first time using their UC San Diego log-in credentials. 
• Students will be asked to review and update their personal information in TSS upon initial login, including: 

  • Mailing Address
  • Lived/chosen name
  • Direct deposit information 
  • Emergency contact information 

• The Schedule of Classes will be made available to students and they will receive an email instructing them to book classes.
• Expected mid-July: For continuing students, Fall 2026 course booking (formerly “enrollment”) opens. This is a change in timeline from previous years (for this year only). For more details on this change, read the campus notice.
• Students will see and begin using their new Triton Student Number (TSN).

August 2026: 

• For new and transfer students, Fall 2026 course booking (formerly “enrollment”) opens. 
• August 6: New students can start authorizing their payer. 
• By August 31: New students will need to authorize their payer if they want their payer to receive the Fall e-bill notice. 
• Current students do not have to reauthorize current payers.

Students will receive detailed instructions/updates directly through university communications channels, such as campus notices and emails.

Parents and families can help by encouraging students to:

• Review university messages related to TSS as they are released.
• Access the support links below. 
• Check their schedule of classes and booking selections carefully once schedules are published.
• Allow extra time for course booking during early periods of the transition.
• Use official support channels below if something looks incorrect. University staff are learning this new system alongside students and families. We appreciate your patience and understanding during this time of change as we navigate the transition to TSS together. 

• Review the TSS Student Information slide.
• Review the Campus Notice issued to students May 5, 2026.
• Check out the TSS Project Website for general information, updates, project news and FAQs.

• Connect with other resources on campus:

  • HDH Undergraduate Housing
  • HDH Graduate and Family Housing
  • Financial Aid Services
  • International Services and Engagement Office
