The Teacher Activities tab. This is where a Teacher can enter what activities they can teach and to what level. 

Teachers can add activities using the Add Activity button. Here they can select the Activity and Level from a drop down list. 

Teachers are also able to edit these entries by clicking the pencil icon. This might be used if a teacher needs to update the level they can teach.

This data also pulls through into Xperios which the Admin team can use when scheduling new lessons.
