For participating Districts, Stopfinder gives parents and guardians access to view and share their student’s bus stop assignments as well as communicate with the Transportation Department. With Stopfinder GeoAlerts, app users can create alert zones at any stop or school or along your student’s route. Stopfinder users will be notified when their student’s bus has arrived at or departed from an alert zone. Know where the bus is and know your student has arrived at or departed from any location along their assigned bus route. Stopfinder Forms allows app users to complete electronic forms sent from their district through the Stopfinder app. Stopfinder users can view new forms and submitted forms through the Stopfinder Message Center. Estimated Time of Arrival (ETA) notifications can be configured by Stopfinder app users to display the bus’s ETA based on their student’s assigned stop and the bus’s location. ETA notifications appear on the student’s schedule in the Stopfinder app and inform users the amount of time until the bus arrives at their student’s assigned stop. Control who can see your student’s assigned trip stops, view attendance history, and receive notifications when attendance has been taken or a vehicle substitution has been made. Send and receive messages from the school district’s Transportation department.
