If your classroom straddles two divisions (e.g. primary & junior for a grade 3/4 split) we recommend creating two different classrooms as the tone of the comments will be different for each of the grades.
If your split grades are in the same division (e.g. a grade 1/2 split) then we recommend only one classroom for ease of report management.
To create an additional classroom:
Click on "Classrooms" from the top, main menu and then "+ Add Classroom"
Please note that multiple classrooms is a Full Access feature.
