The academics module is a way for someone logged in as a school administrator to see all the attendance, grades, lesson comments etc., When you use the Academics Module you are basically looking at the system as a “super teacher” but whereas a teacher can only see their groups etc., you will be able to see all of the school’s groups regardless of who teaches them, so you will need to filter to find the items you are looking for.
To find out more about these items look in the Teacher User Guides for explanations.
