Dismissal changes
All afternoon dismissal changes go through the KidAccount app, one-time or recurring (for example, car rider to bus rider). Same-day changes must be in by 1:00 PM.
Late sign-in
Students arriving after 8:30 AM sign in at the iPad kiosk in the Front Office with their Student ID badge.
Early check-out
A parent or authorized person signs the student out at the Front Office kiosk and scans their driver's license. For safety, no early check-outs from 2:00 PM to 3:00 PM for any reason.
Car line
Display your student's Dismissal Sign on the dashboard so staff can scan the barcode. Without the sign, show a valid photo ID.
Bus riders
Drivers scan each student's ID badge at boarding. Students need their badge ready every afternoon.
Absences
Parents must notify the school office whenever a child will be absent. Use the online absence form, or report it through KidAccount.
