Just this afternoon I got my approval for CourseKit for our domain! It looks like it is 2 separate functions: Assignment collection and File sharing. It's the basic core functions of Google Classroom of collecting papers or passing out and collecting papers.
Here's some more reading: https://support.google.com/edu/coursekit#topic=9069280
I hope to do some testing and see how to best implement this. Setup is as simple as copy/paste LTI settings.
From the help center:
Use Google Docs and Drive to create and collect assignments, give feedback to students, and share course materials within the learning management system (LMS) you’re already using. Google's free Course Kit comes with assignment and file-embed tools. So, instructors can integrate G Suite's collaboration capabilities into learning workflows.
To save you time for more personalized feedback, Course Kit includes a customizable comment bank that lets you quickly insert commonly used comments. If you type the same comment for many students, you can save the comment in the comment bank. Later, when you review other assignments, search for your saved comment and insert it. The comment bank is tied to your G Suite for Education account, so you can access saved comments from any device.
Initially this looks really awesome!!!! I will be testing it out over the next couple of days.
