Class type is a new way to organise your classes to help you to view classes more effectively.

In the school settings, navigate to the class settings tab. Here you'll see a section allowing you to add class types of the class types you need.

Now when you add or edit classes, they will be an option to add the class type.

Now you can use the calendar to select which class types you want to view.

When you export the class data using Class Export, you'll be able to filter by class type.
