Let's see if I'm interpreting you correctly:
Case one: You have a dashboard for a nurse, and want to display the kids enrolled in the school for that nurse. If your dashboard 'caller of the page' entity is 'nurse', then you can easily put either a datagrid or a listview in, and use xpath to get the list. The xpath for this is dead-easy. In fact, Mendix pretty much does it for you. When you select the input entity for the grid, Mendix will also show 'nurse' (caller of the page) at the top of the list. You can drill down via the references via school to kids. The appropriate xpath is automatically generated.
Case two: Show the related parents for the kids. Now that you have a dataview with a datagrid, you might as well use it. Datagrids can display column data over associations. Add a new column to the datagrid and click it. Select 'datasource'. You will also see references as possible sources of input. Open the reference to 'parent' and select 'name'. For each kid in your datagrid you will now also see the name of the parent.
Case three: Grade for a particular nurse. Where are these stored? And are you referring to the kids grades? A grade specific for the nurse? The average grade for all kids for that nurse?
