If your district offers guardians access to documents on the district's public site, then you are going to love this! You were always able do this, but before parents could only see curriculum units. However, now, they can see Google Docs too! And it's simple.
To do this, make sure folder permissions are set up properly in OnCourse. In other words, locate the proper folders, and set permissions to provide Read Access to All Anonymous Users. Also, be sure that you've turned on public permissions for your Google Doc. Now, when guardians click on the district link, they will see Google Docs as well as Curriculum Units and be able to access both!
