What Professors Can See — and What They Cannot
Short answer: Your professor can see the submission attached to their assignment (similarity report, AI writing panel if enabled, metadata like upload time and file name). They generally cannot open a personal dashboard listing every Turnitin file you have ever submitted at your university unless your institution gives them that access through separate records—and that is uncommon for a single course instructor.
What instructors typically see for one assignment:
| Visible to instructor | Usually not visible |
|---|---|
| Latest uploaded file for that assignment | Full version history when resubmissions overwrite prior files |
| Similarity Report and AI Writing Report (if licensed and enabled) | Unrelated third-party pre-check reports you ran at home |
| Submission date, resubmission count (in some LMS views), filename | Every draft you saved only on your laptop |
| Match highlights to sources, including anonymous student-paper matches | Full text of another student’s paper without a paper-view request |
Turnitin is a review tool inside a course workflow—not a student surveillance app. Visibility is controlled by assignment settings your instructor chooses: when reports generate, whether students can resubmit, whether papers enter a repository, and whether students can view their own reports (Turnitin assignment settings documentation).
Beginner takeaway: Professors see what the assignment inbox holds right now, plus the reports Turnitin generates for that file—not a secret archive of every check you ran on random websites.
How Turnitin Stores Your Paper in the Repository
When you submit through your university, Turnitin compares your file against selected repositories. Instructors often choose whether student papers are stored in the standard (global) student paper repository, an institutional repository, both, or neither (Turnitin assignment settings).
That storage choice matters for future submissions—not for letting your current professor scroll through old uploads:
- Student paper repository: New work is compared against prior student submissions across institutions that use Turnitin. A match may appear as an anonymous source (e.g., “Submitted to [institution]”).
- Institutional repository: Work is compared against papers previously submitted at your school.
- Do not store: A similarity report still runs, but the file may not be added to a repository for later matching—settings vary by assignment.
So “previous submissions” often show up as similarity matches, not as a folder your professor opens casually. If last semester’s essay is in a repository your new assignment checks against, Turnitin may flag overlapping text—self-plagiarism review is a policy question, not automatic proof of misconduct.
If you want to preview similarity and AI signals on your current draft before the graded upload—without guessing what the repository will surface—run official Turnitin reports on the exact file you plan to submit.

Resubmissions on the Same Assignment: Overwrite, Not Archive
A common fear sounds like this: “I submitted a rough draft at 9 p.m. and a polished version at 11 p.m.—will my professor compare both?” In the standard overwrite workflow, usually no. Turnitin’s student guidance states that resubmitting overwrites your previous submission, and overwritten versions—including prior reports and feedback—cannot be restored (Turnitin: Resubmitting and managing submissions).
Operational details beginners should know:
- Resubmissions require instructor permission. If resubmissions are disabled or the due date has passed, you may be locked to your first file unless the instructor deletes the submission, grants an extension, or uploads on your behalf (Turnitin: wrong paper submitted).
- Only the latest submission is available to instructor and student in many configurations (institutional FAQ on similarity settings).
- Resubmitted files do not match against each other in the same assignment once overwritten—Turnitin’s guide notes that overwritten prior submissions will not match against each other in your Similarity Report.
- Pacing limits exist. Students may resubmit up to three times within 24 hours on some Standard Assignments; additional attempts can trigger waiting periods for new reports.
Exception mindset: Some courses use draft workflows, portfolio tools, or LMS revision histories outside Turnitin. Always read the syllabus—but inside classic Turnitin overwrite mode, assume your professor sees one live file per assignment slot.
Can Professors See Papers You Submitted in Other Courses?
Not directly by default. Instructors do not receive a universal “student submission history” pane listing every essay you uploaded to Turnitin across departments. Instead, they may encounter evidence of prior work in two ways:
1. Similarity matches in the report
If an older paper sits in a repository this assignment checks, overlapping passages can highlight. Your professor sees matched text segments and an anonymous label—not necessarily your name attached to the older file.
2. Formal paper-view requests
When a match points to another class or institution, privacy rules (including FERPA in the US) block automatic full-text access. The instructor must send a paper view request; the owning instructor decides whether to release the text (University of Missouri System guidance; Imperial College London staff guidance). Many institutions do not allow automatic sharing.
Self-plagiarism scenario: Reusing a paper you already submitted for credit in another course can violate academic integrity even when you are the author. Turnitin may surface the overlap; your professor interprets it against policy. Recycling your own lab report into a new argumentative essay without disclosure is a syllabus question—ask early.
Cross-institution scenario: Submitting the same manuscript through a friend’s account, a prior university, or a consumer check that stores work in Turnitin’s ecosystem can create later matches. Document legitimate reasons (prior coursework, conference draft, supervised revision) before upload if reuse is intentional and permitted.
Practice Checks, Draft Folders, and Third-Party Previews
Students often mix three different “checks.” Each has different visibility:
| Check type | Who sees it |
|---|---|
| Graded course assignment submission | Instructor for that course (per assignment settings) |
| Instructor-created practice / draft Turnitin folder | Usually the course teaching team for that folder |
| Independent pre-submission service | You (and the service operator under their privacy policy)—not your professor’s LMS inbox |
| Turnitin Draft Coach (where offered) | Turnitin states only the student who ran the report can view those results |
A third-party Turnitin check you run before the real deadline does not appear as an extra row in your professor’s gradebook. It may, however, leave a repository footprint depending on how that service processes files—another reason to use providers that do not archive your paper to shared databases.
Read the detector your school actually uses. Consumer checkers that are not connected to your LMS will not show up on your instructor’s screen—but they may also not mirror institutional settings. When your course routes work through Turnitin, the relevant preview is the official Turnitin similarity and AI writing reports for the file you will upload—not a pile of unrelated dashboards.
What Instructors See in the Assignment Inbox
Beyond the PDF or Word file, instructors typically open:
- Similarity Report: Percentage and color-coded matches to web, publications, and student paper repositories. Turnitin emphasizes this is not an automatic plagiarism verdict—staff review matches in context (Imperial College London).
- AI Writing Report (if enabled): Model estimate for qualifying prose. Sub-20% bands often display as *%; 0% is the usual explicit low numeric outcome students screenshot. Instructors apply judgment; Turnitin advises AI indicators should not be the sole basis for misconduct findings (Turnitin: Using the AI Writing Report).
- Submission metadata: Timestamp, filename, occasional resubmission indicators, and LMS user identity.
They do not automatically see:
- Every edit pass in Google Docs unless you submit each pass.
- Unrelated GPTZero or Copyleaks PDFs sitting on your desktop.
- Private notes you never uploaded.
Near the due date, some assignments regenerate similarity reports so submissions compare against classmates’ work in the same pool (institutional FAQ). That can change your similarity percentage even if you did not edit the file—plan previews before the final regeneration window if your instructor allows resubmissions.
What to Check Before You Submit
Use this checklist while you still control the file and the clock:
- Read syllabus rules on reuse, collaboration, AI tools, and self-plagiarism.
- Confirm resubmission settings—can you overwrite before the deadline, and how many attempts per 24 hours?
- List prior submissions of the same text (other courses, old universities, conference versions) and gather proof of authorship if reuse is allowed.
- Open similarity expectations—quotes, bibliography exclusions, and repository settings you cannot change but should anticipate.
- Preview the exact upload file with official Turnitin similarity and AI writing reports when your campus does not offer a student pre-check.
- Email your instructor when policy is unclear—especially for intentional recycling of your own prior graded work.
Before you upload
Step 5 is where many students learn whether an old repository match or AI flag will surface on this file: preview both similarity and AI on the version you plan to submit. If you have not done that yet, check once while you can still edit.

FAQ
Can professors see all my previous Turnitin submissions?
No—not as a default master list. Professors see submissions connected to assignments they manage. Older work may reappear only as similarity matches if stored in repositories your new assignment checks, not as a browsable history of every file you ever uploaded.
If I resubmit, can my professor see my first draft?
Usually no when resubmissions overwrite the prior file. Turnitin’s guidance says overwritten submissions and their reports cannot be restored. Assume instructors see the latest upload unless your course uses a separate non-overwriting workflow.
Can professors see Turnitin submissions from other classes?
Not automatically. They may see anonymous match indicators in the Similarity Report. Viewing the full other-class paper typically requires a paper view request that the original instructor can approve or deny under privacy rules.
Will a pre-check show up in my professor’s inbox?
No. Independent pre-submission checks do not create an extra row in your LMS assignment. Choose services with clear privacy practices; repository behavior depends on the provider’s processing rules.
Does Turnitin store my paper forever?
It depends on assignment repository settings. Many institutional submissions enter the student and/or institutional paper repository for future matching. Ask your campus integrity office if you need certainty about retention.
Can professors see my AI score on every old submission?
They see AI writing reports for submissions they still hold in active assignments with AI features enabled—not a retroactive AI timeline across your entire academic career. Overwritten submissions lose their attached reports.
What if I submitted the same essay twice for credit?
That is potential self-plagiarism under many policies, even if you authored the text. Turnitin may highlight overlap; consequences depend on your institution. Disclose reuse or rewrite with new analysis when reuse is not permitted.
Where can I preview official Turnitin reports before submitting?
If your university does not offer a student pre-check, upload your draft to a service that returns official Turnitin similarity and AI writing reports—the same report types instructors see in institutional systems. Turnitin0 delivers both on .docx, .pdf, or .txt files, does not archive your paper to third-party databases, and typically returns results within minutes.
