In Blippit Boards there's a category of tags specificially to scaffold the recording of Governor visits and updates with subject leaders. Read more about it on the blog.
The teacher can record and tag a visit to make Governor visits part of your overall curriculum impact monitoring activity. Giving governors access to Blippit Boards supports them in being able to understand what’s going on in a particular subject.
With governor accounts, don't make them into Admins.
