Bus Schedule on Early Release Days:
Buses typically begin their normal routes just after the early dismissal times for each school level. We recommend using the “Here Comes the Bus” app to track your child’s bus in real-time on a map.  You can download the app in the Apple or Google app store and then enter the Cobb County School District code 87881.

This information is current as of June 10, 2022, however the schedule is subject to change.
