Confused about whether to write masters degree or master’s degree? You are not alone, as many people hesitate when using this phrase in academic writing, resumes, and everyday English.
At first glance, both forms may seem correct, but the apostrophe can change the grammatical structure and meaning. Understanding the correct usage can help you write more clearly and confidently. You are talking about an academic qualification or describing a degree that belongs to someone, the right form matters.
In this guide, we will explain the difference between “masters degree” and “master’s degree” in simple English. You will also learn which form is standard, how to use it in sentences, and how it differs in British and American English.
Quick Answer
The correct form is master’s degree with an apostrophe before the letter s.
The form masters degree without an apostrophe is generally considered incorrect in standard English grammar when referring to an academic qualification.
Correct:
- She earned a master’s degree in Education.
- He completed his master’s degree in Computer Science.
Incorrect:
- She earned a masters degree in Education.
- He completed his masters degree in Computer Science.
The rule is the same in both British English and American English.
Meaning of the Correct Form
The term master’s degree refers to a postgraduate academic qualification earned after completing a bachelor’s degree. The apostrophe shows possession, meaning that the degree belongs to a “master.”
Historically, the title comes from the Latin word meaning teacher or master of a subject. Therefore, the degree is literally a degree of a master, which explains the possessive apostrophe.
Examples include:
- Master’s degree in Business Administration
- Master’s degree in Engineering
- Master’s degree in Psychology
- Master’s degree in Education
- Master’s degree in Data Science
A master’s degree usually requires one to two years of study after completing undergraduate education. However, the duration varies depending on the country, university, and programme.
British English Examples
- Sarah completed her master’s degree at university in Manchester.
- James is studying for a master’s degree in History.
- My sister received her master’s degree last year.
American English Examples
- Emily earned her master’s degree in Economics.
- David is pursuing a master’s degree in Computer Science.
- My friend recently finished his master’s degree programme.
Although vocabulary and spelling differences often exist between British and American English, this grammatical rule remains the same.
Meaning of the Incorrect Form
The phrase masters degree without an apostrophe is generally considered grammatically incorrect when referring to the academic qualification.
The mistake usually happens because people assume that the word “masters” is simply the plural of “master.” However, the degree is not referring to multiple masters. Instead, it refers to a degree that belongs to a master, which requires possession and therefore an apostrophe.
Many websites, social media posts, and informal discussions use the incorrect version. As a result, people often believe it is acceptable. Nevertheless, grammar experts and educational institutions recommend using the apostrophe version.
Examples of incorrect usage include:
- I completed my masters degree in Finance.
- She plans to apply for a masters degree next year.
- He has a masters degree in Marketing.
These examples should all include an apostrophe.
Why the Apostrophe Matters
Punctuation changes meaning in English. Therefore, a small mark such as an apostrophe can completely alter the grammatical accuracy of a sentence.
Consider these examples:
- Master’s degree = a degree belonging to a master.
- Masters degree = grammatically incomplete expression.
The apostrophe acts as an indicator of ownership or possession. Without it, the phrase loses its grammatical foundation.
This rule is similar to other educational terms such as:
- Bachelor’s degree
- Associate’s degree
Interestingly, the word doctoral degree does not require an apostrophe because it follows a different grammatical structure.

British English vs American English Usage
One reason for confusion is that British and American English often have different spelling conventions.
For example:
| British English | American English |
| Programme | Program |
| Organise | Organize |
| Colour | Color |
| Centre | Center |
| Traveller | Traveler |
However, the phrase master’s degree remains identical in both versions of English.
British Usage
British universities typically write:
- Master’s degree
- Master’s programme
- Master’s qualification
American Usage
American universities usually write:
- Master’s degree
- Master’s program
- Master’s qualification
The only difference is the spelling of nearby words such as programme and program.
Why People Get Confused
Several reasons explain why this mistake is extremely common.
Search Engines Show Both Versions
Many websites publish content without proper editing. Consequently, readers see both forms and assume both are correct.
Spoken English Hides the Apostrophe
When people say the phrase aloud, the apostrophe is invisible. Therefore, listeners often write what they hear instead of following grammar rules.
Similar Educational Terms Cause Confusion
Terms such as:
- Masters students
- Masters courses
- Masters programmes
appear without apostrophes in some contexts because they function as descriptive nouns rather than possessive nouns.
For example:
- Master’s degree in Biology.
- Masters students in Biology.
The first needs an apostrophe, while the second often does not.
Informal Writing Encourages Mistakes
Social media posts and online discussions frequently ignore punctuation. Consequently, incorrect forms spread quickly.
Common Mistakes People Make

Using an Apostrophe in the Wrong Place

Incorrect:
- I have two master’s degrees and one masters degree.
Correct:

When You May See “Masters” Without an Apostrophe
There are situations where masters without an apostrophe can be acceptable.
Examples include:

- Masters graduates
In these cases, the word acts as an adjective describing another noun rather than referring to the degree itself.
Examples:
- The university welcomed new masters students.
- Several masters programmes are available online.
- Masters graduates attended the ceremony.
However, once you refer specifically to the qualification, the apostrophe returns.
Correct:
- She completed a master’s degree.
Tips to Remember the Correct Usage
Think About Ownership
Ask yourself:
“Who owns the degree?”
The answer is:
“The master owns the degree.”
Therefore:
master’s degree.
Remember Bachelor’s Degree
If you already write bachelor’s degree, then master’s degree follows exactly the same rule.
Use the Phrase “Degree of a Master”
Replace the phrase with:
“Degree of a master.”
This naturally leads to:
“Master’s degree.”
Check University Websites
Most universities consistently use the correct form. Therefore, reading official materials can reinforce proper usage.
Create a Simple Memory Trick
Remember this sentence:
The degree belongs to the master, so the apostrophe belongs in the phrase.

Major style guides support the use of master’s degree.
These include:
