Bachelors or Bachelor’s: Difference, Correct Apostrophe Use, Meaning, and Memory Tips Explained

Bachelors and bachelor’s are both correct, but they mean different things. Bachelors is the plural form of bachelor, meaning more than one unmarried man or more than one bachelor-level degree.

Quick Answer

Use bachelors when you mean more than one bachelor.

Use bachelor’s when talking about a degree or something belonging to one bachelor.

The simple rule is: bachelors means more than one, while bachelor’s usually means a degree or ownership.

Bachelors or Bachelor’s: What Is the Difference?

The difference between bachelors and bachelor’s is number and possession. Bachelors is plural. It refers to multiple people or multiple bachelor-level degrees. Bachelor’s has an apostrophe before the s, so it shows possession or connection.

Word	Meaning	Example
Bachelors	More than one bachelor	The event was open to bachelors.
Bachelor’s	Belonging to one bachelor; bachelor-level degree	She has a bachelor’s degree.

If you are only making the word plural, do not use an apostrophe. If the sentence shows ownership or refers to a degree, bachelor’s is usually correct.

What Does Bachelors Mean?

Bachelors is the plural of bachelor. Traditionally, a bachelor is an unmarried man. In modern use, bachelor can also refer to an academic degree level.

Examples:

• The party was full of young bachelors.
• Two bachelors lived in the house next door.
• The article listed the city’s most eligible bachelors.
• The school offers bachelors in business, nursing, and education.

In each example, bachelors means more than one. There is no ownership, so there is no apostrophe.

What Does Bachelor’s Mean?

Bachelor’s is the singular possessive form of bachelor. It means something belongs to or is connected with one bachelor.

Examples:

• The bachelor’s home was simple.
• The bachelor’s schedule changed after he moved.
• The bachelor’s choice surprised everyone.

However, the most common use is bachelor’s degree. In this phrase, bachelor’s shows the degree level. It is the normal spelling in everyday writing.

• She earned her bachelor’s degree in English.
• A bachelor’s degree can help with many career paths.
• He is finishing his bachelor’s this year.

Why Is It Bachelor’s Degree?

The phrase bachelor’s degree uses an apostrophe because the degree is connected to the bachelor level. The word bachelor’s acts like a possessive form.

The structure is:

• bachelor + ’s + degree = bachelor’s degree

This is similar to:

• master’s degree
• associate’s degree
• doctor’s appointment

In normal writing, bachelor’s degree is the safest and most common form. Do not write bachelors degree when you mean one undergraduate degree.

Bachelor’s Degree or Bachelors Degree?

Bachelor’s degree is the standard form. Bachelors degree is commonly seen, but it is usually missing the apostrophe.

Incorrect:

• She has a bachelors degree.
• He finished his bachelors degree online.

Correct:

• She has a bachelor’s degree.
• He finished his bachelor’s degree online.

A helpful test is to ask whether the word is describing a degree level. If yes, use bachelor’s with an apostrophe.

Bachelors, Bachelor’s, or Bachelors’?

There is also a third form: bachelors’. This is the plural possessive form. It means something belongs to more than one bachelor.

Form	Meaning	Example
Bachelor	One unmarried man or degree level	He is a bachelor.
Bachelors	More than one bachelor	Many bachelors attended.
Bachelor’s	Belonging to one bachelor; degree form	She earned a bachelor’s degree.
Bachelors’	Belonging to more than one bachelor	The bachelors’ apartment was messy.

Bachelors’ is less common, but it is useful when multiple bachelors own or share something.

When to Use Bachelors

Use bachelors when you are talking about more than one bachelor and no ownership is involved.

• The city has many bachelors.
• The dating show introduced five bachelors.
• Both bachelors decided to move away.
• The college lists several bachelors under its degree programs.

If the word simply means “more than one,” use bachelors without an apostrophe.

When to Use Bachelor’s

Use bachelor’s when talking about a bachelor’s degree or something belonging to one bachelor.

• She completed a bachelor’s in psychology.
• He wants to earn a bachelor’s degree before applying for graduate school.
• The bachelor’s car was parked outside.
• The bachelor’s quiet lifestyle suited him.

In education writing, bachelor’s is especially common. You can say a bachelor’s degree or simply a bachelor’s.

• She has a bachelor’s.
• He is working toward his bachelor’s.

Capitalization: bachelor’s or Bachelor of Arts?

Use lowercase for general references:

• She earned a bachelor’s degree.
• He has a bachelor’s in history.

Use capitals for the official degree name:

• She earned a Bachelor of Arts.
• He completed a Bachelor of Science in Nursing.

The apostrophe is used in bachelor’s degree, but not in formal degree titles like Bachelor of Arts or Bachelor of Science.

Common Mistakes

A common mistake is leaving out the apostrophe in bachelor’s degree.

Incorrect:

• I have a bachelors degree.

Correct:

• I have a bachelor’s degree.

Another mistake is using bachelor’s when only a plural is needed.

Incorrect:

• Three bachelor’s live in that building.

Correct:

• Three bachelors live in that building.

Do not use apostrophes just to make a word plural. Apostrophes usually show possession or connection, not number.

How to Remember the Difference

Use these memory tips:

• Bachelors has no apostrophe, so it simply means more than one.
• Bachelor’s has apostrophe + s, so it shows possession or degree connection.
• Bachelor’s degree is the standard phrase.
• Bachelors’ means something belongs to more than one bachelor.

A simple memory sentence is: No apostrophe for more than one; apostrophe for a degree or ownership.

You can also remember it this way: If the word comes before “degree,” use bachelor’s.

Final Answer

Bachelors means more than one bachelor. Example: Several bachelors attended the event.

Bachelor’s usually means a bachelor’s degree or something belonging to one bachelor. Example: She earned a bachelor’s degree.

To remember the difference, look for the apostrophe. Bachelors is plural. Bachelor’s shows possession or the degree form, especially in bachelor’s degree.
