Master’s or masters can look almost identical, but they have different grammatical functions and meanings. Master’s normally refers to an academic qualification, while masters is the plural of master and can describe several experts, skilled people, or other individuals. Knowing the difference helps prevent errors in resumes, university applications, academic writing, and professional documents.
Master’s vs Masters | What’s the Difference?
The main difference between master’s and masters is the apostrophe and what the word represents.
Master’s is a possessive singular form that is most commonly used in the established phrase master’s degree. It identifies an advanced academic qualification normally completed after undergraduate study. The word can also stand alone when the context makes the meaning clear, as in “She is studying for her master’s.”
Masters, without an apostrophe, is generally the plural of master. It refers to more than one master. Depending on context, a master can be an expert, skilled practitioner, authority figure, champion, or person with extensive knowledge.
The distinction becomes particularly important in formal writing. Writing masters degree instead of master’s degree is generally considered incorrect when referring to the academic qualification.
Master’s vs Masters Comparison
| Feature | Master’s | Masters |
|---|---|---|
| Grammatical form | Possessive singular | Plural noun |
| Main meaning | Usually an academic degree | More than one master |
| Common phrase | Master’s degree | Masters of a particular field |
| Apostrophe | Yes | No |
| Academic use | Very common | Not normally used for the degree |
| Professional use | Resumes, applications, biographies | Experts, skilled professionals |
| Example | She earned a master’s degree. | The masters shared their knowledge. |
| Meaning | One academic qualification | Several masters or experts |
Quick Recap
Use master’s when you mean an academic degree.
Use masters when you mean more than one master.
The apostrophe in master’s is important because it distinguishes the academic expression from the plural noun.
For formal academic writing, master’s degree is the standard form.
Is Master’s or Masters a Grammar, Vocabulary or Usage Issue?
The difference between master’s and masters involves grammar, punctuation, vocabulary, and usage, but grammar and usage are the most important factors.
The two forms are not normally interchangeable. The apostrophe in master’s indicates a possessive construction that has become established in the phrase master’s degree.
By contrast, masters is normally a plural noun. If a sentence refers to several experts, artists, teachers, craftsmen, or other people who can be called masters, the plural form is appropriate.
The distinction is especially important in formal English. A university application, resume, academic paper, professional biography, or official document should use master’s degree rather than masters degree.
Informal online writing sometimes removes apostrophes because people type quickly or follow casual spelling habits. However, informal usage does not make the spelling preferable in polished writing.

|---|---|---|

| Can it refer to people? | Occasionally in possessive constructions | Yes |

How to Use Master’s Correctly
Use master’s when you are referring to a master’s degree.
The most common expression is master’s degree, such as:
“She earned a master’s degree in psychology.”
“He is pursuing a master’s degree in computer science.”
“Her master’s degree helped her qualify for the position.”
You can also use master’s without the word degree when the context is obvious:
“She completed her master’s last year.”
“I’m applying for a master’s in finance.”
In each case, the apostrophe remains part of the standard spelling.
Master’s Usage Examples

Master’s Usage Recap
Use master’s degree for the full academic expression.
Use master’s alone when the meaning is already clear.

How to Use Masters Correctly
Use masters when you mean more than one master.
For example:
“The masters of the craft passed their skills to younger generations.”
“The students studied the techniques developed by the masters.”
“The competition brought together several masters of chess.”
In these examples, masters is plural. There is no apostrophe because the word simply refers to multiple people.

Master’s Degree or Masters Degree?
One of the most common searches related to this topic is to write master’s degree or masters degree.
The standard form is master’s degree.
The apostrophe is required in careful, formal English because master’s is the established possessive form used in the academic expression.
| Form | Correct? | Explanation |
|---|---|---|
| Master’s degree | Yes | Standard academic expression |
| masters degree | No | Missing the apostrophe |
| Master’s degrees | Yes | Correct plural form |
| masters degrees | No | Missing the apostrophe |
| Master’s | Yes | Acceptable shortened form |
| Masters | Usually no | Not the standard shortened form for the degree |
Example
Correct:
“She earned a master’s degree in engineering.”
Incorrect:
“She earned a masters degree in engineering.”
The difference is only one punctuation mark, but that punctuation mark changes the grammatical form.
Master’s or Masters in Resumes and Applications
Academic qualifications frequently appear on resumes, CVs, university applications, LinkedIn profiles, professional biographies, and employment forms.
Because these documents represent your education and professional background, grammatical accuracy matters.

Master’s and Masters in Modern Technology and AI Tools
The distinction also matters in modern technology because professional profiles, AI generated resumes, educational platforms, and career websites frequently process academic information.
An AI writing tool might produce:
“She holds a master’s degree in data science.”
That is the appropriate form for an academic qualification.
Technology can also use masters correctly when discussing experts:
“The masters of cybersecurity developed advanced security methods.”
The important point is that artificial intelligence does not eliminate grammatical distinctions. AI tools can suggest language, but writers should still review punctuation and meaning before publishing professional or academic material.
Technology Usage Table
| Digital Context | Recommended Form | Example |
|---|---|---|
| AI resume | Master’s degree | Master’s degree in Data Science |
| LinkedIn profile | Master’s degree | Holds a master’s degree in Computer Science |
| University website | Master’s degree | Apply for a master’s degree program |
| AI article about experts | Masters | Masters of programming shared their techniques |
| Online course profile | Master’s degree | Pursuing a master’s degree in AI |
| Professional portfolio | Master’s degree | Master’s degree in Information Technology |
Master’s Degree Plural: Master’s Degrees
A frequent source of confusion is what happens when someone has more than one master’s degree.
The correct form is master’s degrees.
Notice that the apostrophe stays in master’s, while degree becomes plural.
| Meaning | Correct Form | Example |
|---|---|---|
| One degree | Master’s degree | She earned a master’s degree. |
| Two or more degrees | Master’s degrees | She earned two master’s degrees. |
| Several masters | Masters | The masters gathered together. |
This distinction is useful because writers sometimes assume that the plural of master’s degree should be masters degrees. That removes the apostrophe incorrectly.
Etymology of Master’s and Masters
The word master has a long history in English and is related to older words associated with authority, expertise, leadership, and skill.
The academic expression master’s degree developed from the possessive construction associated with the status or level of a master. Over time, the phrase became a standard term for an advanced university qualification.
The plural masters follows the ordinary English plural pattern in which an s is added to the singular noun.
Understanding this history is helpful because it explains why the two forms look so similar but function differently.
Expert Style Principle
“Punctuation is not merely decoration; it helps readers understand grammatical relationships.”
That principle is especially useful here. The apostrophe in master’s helps distinguish the academic expression from the plural noun masters.
Two Practical Case Studies
Case Study 1: University Application
Consider this sentence:
“I recently completed a masters degree in public health.”
The intended meaning is obvious, but the spelling is not standard for formal academic writing.
The corrected version is:
“I recently completed a master’s degree in public health.”
The change is small, but it improves grammatical accuracy and professional presentation.
Case Study 2: Professional Profile
Now consider:
“The masters of software development contributed to the project.”
Here, masters is correct because the sentence describes several highly skilled people.
If the writer instead wants to describe one person’s academic qualification, the sentence would be:
“She holds a master’s degree in software engineering.”
Case Study Comparison
| Case | Intended Meaning | Correct Form | Result |
|---|---|---|---|
| University application | One graduate qualification | Master’s degree | Grammatically appropriate |
| Professional profile | Several experts | Masters | Grammatically appropriate |
| Resume | One academic qualification | Master’s degree | Formal and clear |
| Article about experts | Multiple skilled people | Masters | Correct plural noun |
