On the Contacts tab, there is a smaller tab in the right most position labeled Parents - Students map. It allows you to view, create, and change the set of students that each parent has.
Select the Contacts tab, and then select a contact by searching on the left hand side.
After a contact has been selected on the left, select the Parent - Students map.
You will see another Contacts section on the right side of your screen which will display the parent - student mapping for any contact selected on the left hand section.
If the contact displays in the "Parent list" their children will also show in the "Student list". If they show in the "Student list" then all of their parents will show in the "Parent list".
You can select either a parent or a student from one of the two lists and remove them from the parent or student list by selecting "disconnect parent" or "disconnect student" respectively.
If you enter a contact name in the right hand side and select the contact, "Add to parents" will add the contact to the parent list. They will only remain a parent if you subsequently add a student to them. Search for a different contact on the right hand side, select them and select "add student" to add them to the student list.
