The "Staff Connect" attendance reports will only show summary data for the last 12 weeks. This does not contain individual names but only counts.
If you are looking for group attendance information, then you can utilize the "myGroup" features under the myConnect and view attendance this way.
Note: you will need to be either a leader of that specific group or set as an "Administrator" of that group in the "Connect" tab for that group in Roll Call. See lower left of this screenshot...
Then when you visit the myGroups section of myConnect, you can now view all groups that you are a "leader" or "administrator" of and take/view attendance for that group by person.
