How to Choose a Writing Sample for Grad School

A strong writing sample is the only artefact in your application where admissions readers hear your voice directly—not filtered through a form, a deadline, or a template. Learn how to pick or adapt your best work.

TAKEAWAYS

Key takeaways

Choose depth over breadth: One focused, well-revised piece beats a broad survey every time.
Match your subfield: The sample should reflect the methodology or specialization you named in your statement of purpose.
Always check the length limit: Programs vary widely—verify each one's own requirement before submitting.

What a writing sample is actually evaluated on

When admissions readers assess a writing sample, they are not looking for brilliance or originality alone. They are looking for evidence of disciplinary thinking—the moves that mark someone trained in your field.

Readers typically score on four dimensions, often without consulting a rubric:

Argument construction: Does the work articulate a clear claim? Is that claim supported by logical steps, not just assertion? Can the reader follow the reasoning?
Use of evidence and sources: Are sources integrated into the prose, or just cited? Does the writer engage with ideas critically, or simply report them?
Clarity of prose: Is the writing clear at the sentence level? Does it get out of its own way, or does it bury insight in jargon or filler?
Command of disciplinary method: Does the writer deploy the tools of the field—historical analysis, experimental design, textual close-reading, statistical reasoning—or just talk about them?

All four matter. A piece can be beautifully written but build no real argument. It can have a strong thesis but rest on weak evidence. It can be disciplinarily sophisticated but unclear to someone outside a narrow subfield. The goal is a sample that demonstrates competence in all four.

Choosing which piece to submit—a decision checklist

You likely have several candidates: a seminar paper, an honours thesis chapter, a research article, a conference presentation handout. Use this checklist to narrow down:

1. Does it show your own analysis, not a survey or summary?
A writing sample is not a literature review. It should be a work where you stake a position and defend it. If the piece is mostly you reporting what other people have said, it is not the one.

2. Does it relate to the subfield or methodology you named in your statement of purpose?
A program wants confidence that you know what you are signing up for. If your SOP says you are interested in 19th-century social history, and your sample is about contemporary film theory, the mismatch signals either that you have not thought about your research direction or that you changed direction and did not update your SOP. Either way, it raises doubt. If you have multiple strong pieces, choose one that aligns with what you said you want to study.

3. Is it the most recent and best-revised version you have, not your personal favourite?
Recency matters because it shows your current ability. If you wrote a brilliant paper three years ago but have not written at that level since, a program may wonder whether it was a one-off. Unless the older piece is demonstrably stronger and you can explain why, choose recent work. And choose your best-revised version, even if another piece is the one you enjoyed writing most—the one that shows discipline and revision is the one that signals you can be trained further.

4. Can you submit it as-is, or do you need permission?
If the sample is co-authored, or was written for a course, you may need permission from the instructor or co-author to submit it. Check your course syllabus, institutional policy, or ask the author directly. Some instructors are happy to give permission; others have standing objections. If permission is complicated, consider excerpting or adapting a piece you own outright. (See "What to do if nothing you've written fits," below.)

What to do if nothing you've written fits

You have written plenty, but nothing quite matches the program's expectations or your application narrative. You have three main options:

Write a new, focused excerpt from a longer paper

If you have a thesis chapter or research article that is too long, or that covers too much ground, you can excerpt a single argument and submit just that section—with a framing note. For instance, if your thesis has five chapters and the program asks for 10–15 pages, submit the two pages of introduction and one chapter (12 pages total) with a one-paragraph headnote: "The following excerpt is from Chapter 2 of my undergraduate honours thesis on [topic]. It develops the argument that [your main claim]." This shows the program that you can manage scope.

Adapt a strong course essay

Course essays are fair game—but adapt them first. Remove the prompt reference, update the introduction to work as a standalone piece, and give yourself permission to rewrite weak sections. A course paper written under time pressure often has uneven revision. Give yourself a week or two to bring it up to submission standard. This is not cheating; this is the difference between "a paper I wrote for a grade" and "a writing sample I want my grad school to read."

Ask a professor which existing paper they would recommend

If you are genuinely stuck, email a professor from whom you have taken a seminar or thesis class. Ask: "I am applying to graduate school in [field] and need to submit a writing sample. Which paper I wrote for you best represents my work?" A professor who knows you well can often see possibilities you have missed, and they may have insight into what admissions readers in your target field are looking for.

Trimming to a length limit

Many programs set a specific page or word limit for writing samples—often 15–20 pages for research papers, 5–10 for shorter essays. If your best piece is longer than the limit, here is how to cut it without destroying it:

Cut a whole section, not thin every paragraph

It is tempting to trim a sentence here and a phrase there from every paragraph. Resist. Instead, ask: "Which section of my argument is least essential? Can I remove it without breaking the chain of reasoning?" Often you can cut an entire example, a subsidiary argument, or a lengthy literature review. Your piece will feel tighter and your logic will stay intact. Thin cuts to every paragraph make the whole thing feel nibbled to death.

When submitting an excerpt, add a framing note

If you are submitting a section from a longer work, put a short headnote at the top. Something like: "This excerpt is from my research paper 'The [Title],' written for [Course Name] in [semester]. It develops the argument that [your main point]." One paragraph is enough. It tells the admissions reader what they are looking at and why you chose this piece.

The program's instructions always win

Some programs are strict about page count; others ask for "approximately" a certain length and do not mind a page or two over. Some want the full paper if it exists; others explicitly ask for an excerpt. Read the program's own writing-sample guidelines before you revise anything. Follow them exactly. If a program says "15 pages maximum" and you are over, cut to 15—not 15.5. If it says "submit a self-contained chapter or essay," do not submit chapter 2 in isolation if it depends on chapter 1.

Formatting basics

Format matters because it signals respect for the reader's time and your own discipline. Here are the non-negotiables:

Title page

Include a simple title page with: (1) the title of the work; (2) your name; (3) the course, thesis, or venue where it was written (e.g., "Seminar Paper, HIST 301: Medieval Europe"); (4) the semester or year. Centred, plenty of white space. This is not a formal publication, but it is a document, and documents have covers.

Citation consistency

Make sure your citations follow a single style throughout—MLA, APA, Chicago Notes-and-Bibliography, or whatever your discipline uses. Mixing styles signals carelessness. If you are unsure of the rules for your style, consult the relevant official guide or a citation generator tool. Most universities have style guides available to students. Do not reinvent citation rules to save space.

Margins, line spacing, and font

Use standard settings: 1-inch margins, 12-point serif font (like Times New Roman) for humanities, sans-serif (like Calibri) for social sciences, and double or 1.5-line spacing for readability. These are not arbitrary—they are set by disciplinary convention and make your sample easier to read on screen and in print.

If you are adapting a paper from one course to another, or submitting the same sample to multiple programs, update the header or title-page line that says "Course Name, Professor, Semester" for each submission. A reader who sees "HIST 301, Dr. Smith, Spring 2025" submitted to a program in 2026 knows immediately that you copy-pasted, and copy-pasting (even of a good piece) signals that you are not taking the application seriously.

Frequently asked questions

Can I submit a co-authored paper as my writing sample?

A co-authored paper can work, but only if you have explicit permission from your co-author and, if applicable, your instructor. Before you decide to submit it, be prepared to tell the admissions committee what your specific contribution was to the piece—did you write the introduction, analyze half the data, or draft and revise the whole thing before your partner polished it? If the committee cannot distinguish your work from your co-author's, they cannot evaluate your individual ability. When in doubt, ask your instructor whether a co-authored work meets their expectations for a writing sample, or choose a piece you wrote alone.

Should my writing sample match my proposed research topic exactly?

Not exactly, but it should signal the same field and methodology. If your statement of purpose says you want to work on 19th-century literature and your writing sample is on medieval religious texts, that is a red flag. But if both are in literary history, and both use close-reading as a method, the topic mismatch matters much less. Admissions committees want to see that you can think like a scholar in your chosen field. The specific topic is less important than the fact that your sample demonstrates the skills and habits of mind your program trains.

Can I submit an excerpt of a longer thesis or paper?

Yes, excerpts are acceptable and common. A self-contained chapter or section of argument works well. What matters is that the excerpt can stand alone—a reader should not feel lost or need to have read earlier parts of the paper to follow your reasoning. When you submit an excerpt, include a brief note at the top saying which work it comes from and what argument it develops. This transparency helps the reader understand why you chose that particular section.

Does the writing sample matter as much as the statement of purpose?

Yes. Your statement of purpose tells the committee what you say you can do. Your writing sample shows you doing it. A brilliant statement of purpose paired with a weak writing sample raises doubts about whether you wrote the SOP or whether your writing ability matches your ambition. A solid SOP and a strong writing sample tell a coherent, convincing story. Both matter equally.

What if my best writing is from more than a year ago?

If your best piece is a year or two old and you have nothing as strong since, you can use it—but use it with awareness. Your admissions reader will assume it represents your current level, for better or worse. If you have written since then and improved, the older piece might underrepresent you. If you have written since then and your writing has stayed the same or declined, use the older piece. But if there is a significant time gap, consider whether you can revise or update the older piece to feel current.

Should I hire an editor to polish my writing sample?

Light editing for grammar and clarity is fine and professional. Many universities offer free editing services to students, and using them is smart. What you should not do is hire someone to rewrite the argument or the structure of your piece, or to produce prose so polished that it reads unlike your own voice. Admissions readers can tell the difference between a carefully revised student paper and a heavily ghostwritten one. Your job is to show that you can think and write clearly, not to hide behind professional prose.
