Late Arrival Schedule
On a "Late Arrival Day," the school day begins at 9:30 a.m for students. We follow a shortened school day schedule and school buses run on a 90-minute delay.
While our students arrive later, staff begin work at their regular time. During this time, staff participate in professional learning time by collaborating with one another, working on long-term planning, or participating in professional learning opportunities.
