How materials are shared in Classroom

Classroom works with Google Docs, Google Drive, and Gmail so teachers can assign work to students. Teachers can attach materials—documents, links, images—to the assignment. All activity is online using a computer or a mobile device.

Students sign in to Classroom, see their upcoming work, and complete it online. When  a student turns it in, the teacher sees immediately in the class stream that the work is turned in.

How the assignment flow works




Teacher creates an assignment and attaches files.

  Students attach materials or edit files from the teacher and turn in their work.


Teacher grades the students' assignments.


Students see their grades and can edit their work.




  1. Teacher creates an assignment or question—The teacher can post to one or more classes or to individual students in a class and set a due date. If the teacher attaches materials, they control access to them until the work is assigned to students. As students work on an assignment, the teacher can view progress, add comments, and make edits in the documents. Also, when attaching a Drive file (document, slides, or sheet), the teacher can choose to:
    • Allow students to view the file—All students can read the file, but not edit it.
    • Allow students to edit the file—All students share the same file and can make changes to it.
    • Make a copy for each student—Students receive an individual copy of the file that they can edit. The student’s name is automatically added to the document title. When a student turns in the assignment, the teacher sees the file labeled with the student’s name.

    For details, see Create an assignment or question.

  2. Student turns in work—The student works on the assignment by either viewing a document, editing a shared document, or editing their individual copy of a document. The student can attach files, links, or images to their work. When completed, the student turns in their work. Before the due date, a student can unsubmit work, make changes, and resubmit it. After the student turns in a file from Google Docs, Sheets, or Slides, only the teacher has edit access and can make any changes to it.

    For details, see Submit an assignment.

  3. Teacher grades work—The teacher can write notes on student work, add a grade and return it to the student with individual feedback to each student. Learn more about grading and returning assignments and writing notes on student work.

    Student sees grade—The student sees their grade. If the student’s work includes a Drive file, the student regains edit access to the file and can work on it again, if needed. For details, see View returned work.
