Class sharing allows Heads of Year to see data from classes across a whole year.
Class sharing will give you access to data but you will still need to go into each class to see the data. You can gain access to year group reporting through Seneca Premium by reviewing the whole school class list and adding yourself to any and all relevant classes.
Premium, MIS connected Schools
Premium School without MIS connection?
To see data for individual classes and students, you will need to be a teacher in the classes you want to look at. You need to use your own Seneca teacher account to do this. You can ask the teachers who own the classes to invite you to their Seneca class.
