Following consultation with academic and administrative leadership, the university has moved the Fall 2026 enrollment period to mid-July 2026, instead of May. This one-time change for Fall 2026 supports the upcoming launch of the Triton Student System (TSS).
About the Decision
This revised schedule was approved following detailed planning and review by executive leadership, governance committees, and subject matter experts. The university recognizes this change may affect planning cycles for students, faculty and staff. To minimize the impact, several measures are being considered to safeguard student success, maintain operations, and protect financial and administrative timelines, and will be shared in due course.
This change also provides the necessary time to complete data migration, integrate related systems, and deliver critical training and readiness activities for the university community.
What to Expect
TSS represents one of the most significant technology transformations at UC San Diego in decades, as the university transitions away from the long-standing Integrated Student Information System. Active testing is currently underway to ensure core functions perform reliably, such as class scheduling, registration, and financial transactions.
Staff will begin using TSS as early as February 2026 to prepare for Fall 2026 schedule building and student enrollment. Access will roll out in phases, aligned with major project milestones.
Moving enrollment to mid-July provides additional time for testing, data migration, and training, where supplementary resources will be provided as enrollment begins. This will ensure both staff and students benefit from a stable, well-supported system.
While extensive preparation is underway, a transition of this scale will bring some challenges. Processes may feel unfamiliar at first, and it may take time to adjust. The project team is developing support plans including training, support channels, and real-time assistance during the enrollment period.
