As a parent (in Hillsborough County), there is no place to see "at a glance" grades and/or announcements. The parent "dashboard" (on the website) isn't a dashboard. To see grades and announcements for my 3 kids requires clicking on each of the 20 courses and then clicking on grades in each course. Announcements is also a separate click.
A much more usable "dashboard" would have a filter for student and semester; it would show current (total) grades by class, recent assignment grades across all classes (by date or class), and recent announcements. All on one page without 60 clicks to get the information.
