How students can view comments in documents submitted through Google Classroom

A sizable number of Google Classroom teachers have mentioned that students can not see comments they added to a Google document, spreadsheet, or presentation. It is important to remember that when a student submits a document through Google Classroom, that they are demoted to viewer status. As a viewer of a document, a user can not edit, suggest, or (drum roll), view comments. If you want students to see comments you add, you must elevate their privileges to at least Can Comment. There are two easy, quick ways to accomplish this.

While commenting on a student's document, click share, advanced, and elevate the student from Can View to Can Comment. You'll have to do this for each document.

Or, to enable viewing comments for an entire class with a couple of clicks, go to the assignment in Google Classroom. Select the assignment, click the students for whom you want to enable comment viewing, then click return. All selected user privileges will automatically update.

The included video demonstrates both methods to enable viewing of comments.
