Most students only think about this for one of two reasons: they want a paper back to see where they lost marks, or they are wondering whether an old submission can be reused. The answers are different, so this page covers both.

What professors do with old papers
Coursework and mid-term assessments are usually returned. Final examination scripts usually are not — many institutions advise instructors to retain them rather than hand them back, so that the script still exists if a student queries the mark or requests a remark.
Unreturned scripts typically go to the department or faculty office for storage rather than staying in the professor’s desk indefinitely. Once returned to a student, though, responsibility shifts: if you lose a paper you were given back, the institution generally has no obligation to produce another copy.
How long do professors keep papers on file?
There is no universal figure — it is set by institutional policy, and the range in practice runs from a single term to several years. A published example makes the pattern concrete.
The University of Richmond’s records-retention guidelines specify:
| Record | Retention |
|---|---|
| Exams and graded coursework (if not returned to the student) | One year after course completion |
| Faculty grade books | Five years after course completion |
| Course materials in the LMS | Instructor materials five years; student information unavailable after 60 days unless the instructor downloaded it |
That shape is typical: the script itself has a short retention window, while the record of your grade is kept much longer. Your own institution’s registrar publishes its equivalent policy, and that is the one that governs your case.
Can you reuse an old paper?
Not without permission. Resubmitting your own previous work is generally treated as self-plagiarism, and most institutions define it explicitly. It typically covers:
- Resubmitting a paper you handed in for an earlier assignment
- Reusing substantial passages from your own earlier writing without citation
- Recycling previously collected data as if newly gathered
- Splitting one piece of research across multiple submissions
How seriously it is treated varies. Academics genuinely disagree about whether reusing your own words is comparable to using someone else’s, but that debate does not protect you — what matters is your institution’s written policy, and consequences there can range from a zero on the assessment upward.
There is a straightforward way to stay clear of it. Ask the instructor in advance, in writing, whether you may build on earlier work, and cite your own prior submission the way you would cite any other source. Permission plus citation turns the same act from an offence into normal scholarly practice.
This catches people out most often after deferring or retaking a course, where resubmitting last year’s assignment feels like handing in your own work — which it is, and which is exactly the problem.
Can professors tell if you reuse a paper?
Usually, yes. Most institutions run submissions through a similarity checker such as Turnitin, SafeAssign or Unicheck, and these tools maintain a repository of previously submitted student work that new submissions are compared against.
The practical consequence is that your own earlier submission can be the thing your new one matches. A resubmitted assignment can return a very high similarity score against a paper nobody else ever saw — your own. Institutions can request removal of a submission from a repository, but you should assume by default that a submitted paper stays comparable.
A high similarity score is not a verdict on its own. It is a flag that a human then reviews, and matches against your own prior work are usually obvious to the instructor reading the report.
Why professors keep old papers
Grade disputes and remarks
This is the main reason. If a student challenges a mark, the script has to exist for anyone to check it. Retention windows are generally built around the appeal deadline.
Accreditation and quality review
Departments are periodically asked to evidence how work was assessed. Samples of marked scripts across the grade range are standard evidence for that.
Question security
Where exam questions are reused between cohorts, returning scripts would circulate the paper. Retaining them keeps the assessment usable.
Practicality
Scripts left unclaimed at the end of term have to go somewhere, and departmental storage is simply the default.
Protection for the instructor
A retained script is also the professor’s evidence. If a grade is challenged months later, the marked paper is what demonstrates the mark matched the rubric. Instructors who return everything and keep nothing have no way to substantiate their own decisions, which is part of why departments make retention a policy rather than a preference.
It is worth noting what retention is not for. Professors are not archiving old coursework to catch you out later or to build a file on you. The window is short, the storage is mundane, and the purpose is almost entirely administrative — appeals, audits and assessment security. The one system that genuinely does keep a long-term copy for comparison is the similarity checker, and it does so for every student equally rather than for anyone in particular.
Paper scripts vs digital submissions
The two behave very differently, and most confusion about this topic comes from treating them as one thing.
Paper scripts expire
A physical script occupies physical space, so departments dispose of them on a schedule. Once that window closes the document is genuinely gone — nobody can retrieve it for you.
Digital submissions persist in more than one place
A file submitted online can exist in the learning management system, in the instructor’s own download, and in a similarity-checker repository, each with its own retention rule. The LMS copy is often the shortest-lived of the three — Richmond’s guidance, for instance, notes student information becomes unavailable there after 60 days unless the instructor downloaded it.
The practical upshot is counterintuitive. The copy most likely to still exist years later is not the one your school keeps for your benefit — it is the one held for comparison in a plagiarism-checking database.
Your right to see your own records
In the US, FERPA gives access rights over education records — the right to have access to those records, to seek to have them amended, and to some control over disclosure of personally identifiable information. Those rights belong to the parent while the student is a minor and transfer to the student at 18 or on entering a postsecondary institution.
Two caveats worth knowing before you invoke it. Whether a particular graded script counts as an education record depends on how the institution maintains it, so this is not a guaranteed route to a specific exam paper. And an access right cannot recover something already destroyed under a published retention schedule — which is the practical reason to ask early rather than to argue later.
If your interest is really the mark rather than the document, the grade-appeal process is usually the faster and more appropriate route.
How to get your paper back or request a remark
- Ask early. Retention windows are shorter than people expect — often about a year, sometimes a single term.
- Ask the department office, not only the professor. Unreturned scripts usually sit with the faculty rather than the instructor.
- Check the appeal deadline first if your goal is a remark. It is normally much shorter than the retention period.
- Request feedback rather than the script if the paper is gone. Instructors often still hold the mark breakdown even when the physical script has been disposed of.
- Keep your own copies. Once work is handed back it is yours to look after, and a personal archive is the only version you fully control.
Frequently asked questions
Do professors keep old exams?
Frequently, yes — final exam scripts are often retained rather than returned so they remain available for remarks and appeals. Retention is set by institutional policy and commonly runs about a year for graded work.
Can I resubmit a paper I wrote for another class?
Not without permission. It is usually classed as self-plagiarism. Ask the instructor in advance and cite your earlier work, which makes reuse legitimate at most institutions.
Will Turnitin detect my own old paper?
If your earlier submission went into the repository, yes — a resubmission can match against your own prior work and produce a very high similarity score.
How long are grades kept compared to papers?
Much longer. At Richmond, for example, graded work is kept a year while faculty grade books are kept five years, and your transcript record is permanent.
