No Early Arrivals Unless Scheduled


Students are not permitted or supervised on our playground prior to 8:20 a.m. each school day.

In the interest of safety, please do not send children to school prior to that time unless they have an early arrival scheduled for that day.

If a student has a meeting scheduled with a teacher or a before-school club prior to 8:20 a.m., they may ring the bell and must enter through the school office.


Prompt Pick-Ups After School


All children must be picked up at 3 p.m., unless there is an early release day (see school-year calendar). If your child is not picked up, they will be sent to the office.

If your child is chronically not picked up from school on time, then a meeting will be arranged with the parent and administration.
