Way back when I first wrote the web app, I figured users would need some way to find groups of students, but I wasn't real sure what would work. Most states have some way to select a district or region in the upper right corner, but I thought something else might be needed. So I added the notion of All Students | My Students | My Schools. It looks like this:
It has been there forever, but I think it has caused more trouble than it's worth. There are much better ways to find what you're looking for now, like the "Lists" tab. Some states have already had us remove it from their MIS2000 web app.
I'd love to remove it for your state as well if no one is actually using it. Let us know!
