School Years and Sessions can be added as needed. These are located in the personal icon, settings and then select School Years & Sessions from the general drop-down menu.
You can set up the date range of a school year from this page.
Sandboxes are a useful tool to help you experiment with testing out new routes without making changes to your current ones.
In the School Year & Sessions section of Settings, you can create new Sandboxes for specific school years. You can choose whether or not to copy Schools, Stops, Routes, and Bus Schedules from a previously created Sandbox or simply copy the stops and/or routes that are currently being used. With your new Sandbox created, you can experiment and test things as you wish and use functions that can only be used in a Sandbox like Auto Generate Routes and Auto Consolidate Trips If you eventually decide to, you can utilize those changes you’ve made in your Sandbox in your real Routes.
