Google Docs' suggestion mode is built-in peer review. Students give each other feedback inside the document, not in a separate tool. Every student already has access. The commenting system is intuitive. And suggestion mode lets reviewers propose specific edits without overwriting the original work. You don't need a specialized peer review platform — you need a shared document, clear permissions, and a feedback guide that tells students exactly what to look for.
What you’ll walk away with:
- A structured peer feedback workflow using Google Docs commenting and suggestion mode
- A feedback rubric that produces specific, actionable reviews
- A peer pairing system that works for cohorts of any size
- A debrief process that turns peer feedback into a learning activity
The setup is straightforward: each student creates or uploads their work in a Google Doc, you assign peer pairs, and reviewers leave comments directly on the text. The result is a structured peer review workflow where feedback is specific, anchored to particular passages, and visible to both the author and the instructor.
Why Google Docs for peer feedback
The biggest barrier to peer feedback in online courses is friction. If students have to download a file, mark it up in a separate tool, and re-upload their comments, most of them simply won't do it. Google Docs eliminates that friction because commenting happens right inside the document. You click on a sentence, type your thought, and it appears as a threaded conversation in the margin.
Commenting also feels natural. Students aren't filling out a form or rating items on a scale — they're reacting to specific passages in context. That produces feedback that's more useful than a generic "I liked it" because the comment is physically attached to the sentence it refers to.
Then there's suggestion mode. When a reviewer switches to "Suggesting" (via the pencil icon in the top right), their edits appear as tracked changes rather than direct modifications. Instead of a comment saying "this paragraph is unclear," the reviewer can rewrite the opening sentence as a suggestion and let the author accept or reject it. That level of specificity teaches both the reviewer and the author more than abstract commentary ever could.
Step-by-step: Setting up peer feedback in Google Docs
Create a shared document per student
Each student needs their own Google Doc containing the work to be reviewed. You have two options: students create their own documents and share them with you, or you create a set of blank documents in a shared Google Drive folder and assign one to each student. The second approach gives you more control over permissions. Either way, name the documents consistently — something like "Assignment 3 — [Student Name]."
Set commenting permissions
This is the step that makes or breaks the workflow. The document owner needs to share the document with their assigned reviewer as a "Commenter." Not Viewer, which blocks feedback. Not Editor, which lets the reviewer change the original text directly. Commenter is the right permission level — it allows comments and suggestions without giving full editing access. If you created the documents in a shared folder, you can set folder-level permissions so that everyone in the cohort can comment on any document in the folder.
Provide a feedback rubric or guide
Don't skip this step. Without a rubric, peer feedback tends to be vague, polite, and not particularly useful. Create a short document — half a page is plenty — that tells reviewers exactly what to evaluate. For a writing assignment, you might ask: "Does the introduction clearly state the problem being solved? Is there at least one specific example in each section? Is the conclusion actionable?" Share the rubric as a separate Google Doc that reviewers keep open alongside the work they're reviewing.
Assign peer pairs
Post the assignments clearly — a simple list in your course discussion area or a shared spreadsheet showing who reviews whom. For most courses, pairing each student with two reviewers works well. You can assign pairs randomly, strategically (pairing students with different strengths), or let students choose. Random assignment is the simplest to manage. Make sure every student is both giving and receiving feedback — the learning happens on both sides.
Set a deadline for feedback
Give students a clear window — typically three to five days — to complete their reviews. Specify both a start date and an end date. Without a firm deadline, peer feedback drags on indefinitely and loses its value. A tight window also creates a shared rhythm that makes the activity feel like an event rather than a chore.
Debrief as a group
After the feedback window closes, bring the group together — in a live session, a discussion thread, or a short video — to reflect on what they learned from the process. Ask questions like: "What was the most useful piece of feedback you received?" or "What did you notice about your own work after reading someone else's?" The debrief is where peer feedback becomes a learning activity rather than just an editing exercise.
Tips for better peer feedback
Model good feedback first
Before asking students to review each other, show them what useful feedback looks like. Take a sample document (not a real student's work) and walk through your own commenting process. Show how you anchor a comment to a specific passage, how you phrase a suggestion constructively, and how you use suggestion mode to propose a concrete edit. Five minutes of modeling saves hours of vague comments later.
Limit the scope of each review
Asking a peer reviewer to evaluate everything about a document is asking too much. Narrow the focus to two or three specific dimensions per review round. "This week, focus on whether the examples are specific enough and whether the structure flows logically." A focused review produces deeper comments than a broad one, and it's less intimidating for students who are new to giving feedback.
Use the 'resolve' feature to track follow-through
Google Docs lets the document author mark a comment as "resolved," which collapses it without deleting it. Encourage students to resolve each comment after they've either acted on it or decided not to. This creates a visible record of engagement with the feedback. As the instructor, you can reopen the comment history to see both the original feedback and the author's response.
Limitations to know about
Comments aren't anonymous
Google Docs comments are not anonymous. Every comment shows the reviewer's name and profile picture. For many course activities this is fine — it builds community and accountability. But for situations where honest critical feedback might be inhibited by social dynamics, the lack of anonymity can soften feedback to the point of uselessness. If anonymity matters, you'd need a dedicated peer review tool.
Written feedback lacks tone
The commenting interface can feel awkward for delivering critical feedback. There's no tone of voice, no facial expression — just text in a margin. Students who are uncomfortable giving negative feedback may avoid it entirely, or phrase it so gently that the author misses the point. The rubric helps here, but it doesn't fully solve the problem. Remind students that specific, constructive criticism is a gift, not an attack.
No built-in rubric or scoring system
Google Docs has no built-in rubric or scoring system. You can't attach a rating scale to a comment or generate a summary score from multiple reviewers. The feedback is qualitative and unstructured unless you impose structure through your rubric document. For courses that need formal peer grading with numerical scores, a tool like Peerceptiv or your LMS's built-in peer review feature will be a better fit.
Frequently asked questions
How many peer reviewers should each student have?
Two is the sweet spot for most online courses. One reviewer gives a single perspective that may or may not be helpful. Three or more creates a coordination burden and often produces redundant feedback. With two reviewers, students get enough variety to notice patterns in the feedback without feeling overwhelmed.
What if students leave only superficial comments like "looks good"?
This almost always means the feedback prompt is too vague. Instead of asking students to "leave comments," give them specific questions to answer — for example, "Identify one section where the argument is strongest and explain why" or "Suggest one concrete change to the conclusion." A structured rubric eliminates most low-effort responses.
Can I use Google Docs peer feedback with large cohorts?
Yes, but the logistics shift. With more than 20 students, manually assigning peer pairs becomes tedious. Create a simple spreadsheet listing each student, their document link, and their assigned reviewers. You can also use small groups of three or four instead of pairs, where each person reviews everyone else in the group.

Feedback that builds community
Peer feedback does more than improve individual assignments. It builds a culture where students pay attention to each other's work, learn from different approaches, and develop the skill of giving useful critique — which is itself a transferable skill worth teaching. Google Docs makes the mechanics simple enough that you can focus on the pedagogy rather than the technology. Ruzuku gives you a place to host your course, your discussions, and your peer activities in one environment — so the feedback conversation lives alongside the learning, not in a separate tool.
