If you’ve ever paused mid-sentence wondering whether to write “master’s student,” “masters student,” or “MS student,” you’re not alone. This tiny grammar question trips up undergraduates, working professionals updating their LinkedIn bios, and even seasoned academics drafting cover letters.
The short answer: “master’s student” is the grammatically correct form. “Masters student” is a common but incorrect variation, and “MS student” is a specific, situational term reserved for people earning a Master of Science degree.
But there’s more nuance here than a simple apostrophe rule. This guide breaks down the grammar, the context, and the real-world usage so you never second-guess yourself again.
Understanding the Grammar Behind “Master’s Degree” (The Apostrophe Rule That Changes Everything)
English possessives are formed by adding an apostrophe plus “s” to a singular noun. “Master’s degree” literally means “the degree belonging to a master,” in the sense of someone who has mastered a subject. The apostrophe isn’t decorative. It carries grammatical meaning.
Drop the apostrophe, and “masters” becomes a plural noun instead of a possessive one. That changes the entire structure and logic of the phrase.
✔ Correct
- Master’s degree
- Master’s student
- Master’s program
- Master’s thesis
✘ Incorrect
- Masters degree
- Masters student
- Masters program
- Masters’ student (this incorrectly implies plural ownership by multiple masters)
Once you understand this rule, every version of the phrase becomes easier to evaluate.
Master’s Student vs Masters Student: Which One Is Correct?
Between these two, there’s no real debate in formal or academic English. “Master’s student” is correct because it uses the possessive form to describe someone enrolled in a master’s program. “Masters student” is incorrect because it strips away the apostrophe and turns “master’s” into a plural noun that doesn’t logically connect to “student.”
Style guides, universities, and academic publishers consistently use the apostrophe form. If you’re writing a resume, thesis, email signature, or LinkedIn headline, “master’s student” is the version that signals attention to detail.
What “Master’s Student” Means (Correct)
A master’s student is someone who is currently enrolled in a graduate program pursuing a master’s degree, such as an MA, MS, MBA, MFA, or MEd. The term is broad and applies across every academic discipline, not just science or technical fields.
Examples
- “I’m a master’s student in Artificial Intelligence at Stanford.”
- “She is a first-year master’s student focusing on public policy.”
- “As a master’s student, he balances coursework with part-time research.”
Why It’s Correct
The phrase follows the standard possessive noun structure used throughout English grammar for degrees and qualifications. It shows that the student “belongs to” or is part of a master’s-level program, similar to how you’d say “a bachelor’s degree” or “a doctor’s appointment.”
Masters Student or Masters Student
This heading looks like a typo, and that’s intentional context: even the phrase itself is often mistyped because people aren’t sure which version is right. Whether you write it as “Masters student” or “masters student” (with or without capitalization), both versions are incorrect for the same reason: the missing apostrophe.
Why “Masters Student” Is Incorrect
Without the apostrophe, “masters” reads as a plural noun, as in multiple masters. Grammatically, that doesn’t make sense when paired with “student,” since one student cannot belong to several masters at once. The correct construction requires the possessive form to indicate that the student is part of a single master’s program.
Common places where “Masters student” wrongly appears:
- University marketing pages and blog posts
- Resumes and cover letters
- LinkedIn profiles and bios
- Casual social media posts
- Auto-generated or poorly edited content
✔ Quick Rule:
If you can rephrase the sentence as “a student of the master’s program,” you need the apostrophe. There is no context in standard English where dropping it is correct.
Understanding “MS Student”: Meaning, Context, and When to Use It
“MS student” is not a grammar variation of “master’s student.” It’s an abbreviation with a specific meaning. MS stands for Master of Science, so an “MS student” is someone pursuing a science, technology, engineering, or math (STEM) based master’s degree.
Unlike “master’s student,” which works in any field, “MS student” is field-specific and shouldn’t be used for degrees like an MA (Master of Arts) or MBA (Master of Business Administration).
What “MS Student” Actually Means
An MS student is enrolled in a Master of Science program. This term is widely used in university departments, research labs, and technical resumes because it’s short, precise, and instantly recognizable in academic and professional circles.
Examples of MS Programs:
- MS in Computer Science
- MS in Mechanical Engineering
- MS in Data Science
- MS in Biology
- MS in Statistics
Non-MS Programs:
- MA in English Literature
- MBA in Finance
- MEd in Curriculum Design
- MFA in Creative Writing
When “MS Student” Is Better than “Master’s Student”
“MS student” is the stronger choice when you want to be precise about your field, especially in technical resumes, research papers, or academic bios where specificity matters more than general phrasing.
Examples
- “He is an MS student in Mechanical Engineering researching thermal systems.”
- “As an MS student, she’s currently building a machine learning model for her thesis.”
When NOT to Use It
Avoid “MS student” if:
- You’re pursuing a non-science degree (MA, MBA, MFA, MEd, etc.)
- You want a general, degree-agnostic term
- You’re writing for a broad, non-academic audience unfamiliar with the abbreviation
Formal vs Informal Usage: Master of Science, Master’s Degree & MS
Each term sits at a different level of formality, and choosing the right one depends on your audience and platform.
| Term | Formality Level | Best Used For |
| Master of Science | Most formal | Diplomas, official transcripts, research papers |
| Master’s degree | Formal / neutral | Resumes, academic writing, general conversation |
| Master’s student | Formal / neutral | Bios, emails, LinkedIn, cover letters |
| MS | Informal / shorthand | Resumes, email signatures, casual bios |
| MS student | Informal / field-specific | Technical resumes, STEM contexts |
Professional Hierarchy (Most → Least Formal)
- Master of Science (full formal title)
- Master’s degree
- Master’s student
- MS
- MS student
Example in Context
A university transcript will read “Master of Science in Computer Science.” A resume might shorten that to “MS, Computer Science.” A LinkedIn bio might simply say “MS student at MIT.” All three are correct, but each fits a different setting.

Masters Student Meaning
Even though “masters student” is grammatically incorrect, it’s worth clarifying what people mean when they use it. In almost every case, they intend the same meaning as “master’s student”: someone currently working toward a graduate-level master’s degree. The intended meaning is never in question; only the spelling is wrong.
Common Mistakes Students Make (And How to Fix Them)
Mistake 1: Writing “Masters Degree” Instead of “Master’s Degree”
This is the most frequent error. The fix is simple: always add the apostrophe before the “s” to show possession.
Mistake 2: Using “MS Student” for Non-Science Fields
Calling yourself an “MS student” while pursuing an MBA or MA is inaccurate. Use “master’s student” instead, or name your specific degree.
Mistake 3: Capitalizing “master’s” Randomly
“Master’s” should only be capitalized at the start of a sentence or when part of a formal degree title (e.g., “Master of Science”). In general usage, keep it lowercase: “she is a master’s student,” not “she is a Master’s Student.”
Mistake 4: Using “Master’s Candidate” and “Master’s Student” Interchangeably
These terms overlap but aren’t identical. A “master’s student” is anyone enrolled in the program. A “master’s candidate” typically refers to someone who has met specific requirements and is nearing degree completion, often actively working on a thesis or final project.
Correct Usage Examples (With Side-by-Side Comparison)
Correct Sentence Examples
- “I am a master’s student studying environmental policy.”
- “He earned his MS in Data Science last spring.”
- “She is pursuing a Master of Science in Nursing.”
Incorrect → Corrected
| Incorrect | Corrected |
| I’m a masters student in biology. | I’m a master’s student in biology. |
| She has a masters degree in finance. | She has a master’s degree in finance. |
| He is an MS student in English Literature. | He is a master’s student in English Literature. |
| I’m working on my Masters thesis. | I’m working on my master’s thesis. |
Master’s Student vs Master’s Candidate: What’s the Difference?
While these two terms are often used loosely, they technically describe different stages of the same journey.
Master’s Student
A master’s student is anyone actively enrolled in a master’s program, regardless of how far along they are, from orientation week to final exams.
Master’s Candidate
A master’s candidate has usually completed coursework requirements and advanced to the final stage, often the thesis, capstone, or comprehensive exam phase.
Example
“As a first-semester master’s student, she’s still completing core coursework. By her final semester, she’ll officially become a master’s candidate defending her thesis.”
Masters Student Email Signature
A common real-world question is how to correctly list your status in an email signature. The safest, most professional format looks like this:
- Jane Doe
- Master’s Student, Department of Computer Science
- XYZ University
If your degree is science-based and you want more specificity, you can write:
- John Smith
- MS Student, Mechanical Engineering
- XYZ University
Avoid writing “Masters Student” without the apostrophe in any professional signature, as it can undercut an otherwise polished email.
Common Abbreviations for Master’s Degrees (Not Just MS!)
| Abbreviation | Full Degree Name | Common Field |
| MS | Master of Science | STEM fields |
| MA | Master of Arts | Humanities, Social Sciences |
| MBA | Master of Business Administration | Business |
| MFA | Master of Fine Arts | Creative Arts |
| MEd | Master of Education | Education |
| MPH | Master of Public Health | Public Health |
| LLM | Master of Laws | Law |
Why This Matters
Assuming every master’s degree is an “MS” is a common and easily avoidable mistake. Using the correct abbreviation shows accuracy and reflects genuine understanding of your own field.
Using These Terms in Real Sentences
