Why Is “Years of Experience” So Common?

Is “Years Experience” Correct?
This is where many English learners—and even native speakers—become confused.
In standard English, years experience without an apostrophe or the word of is not considered grammatically correct.Years of Experience or Years Experience.
The reason is simple.
The noun experience needs a grammatical relationship with years. English normally expresses that relationship in one of two ways:
- by using of
- by using the possessive apostrophe
Without either one, the phrase feels incomplete.
Compare these examples:
✔ five years of experience
✔ five years’ experience
✘ five years experience
The third version is missing the grammatical connection between the two nouns.
So why do people still write it?
Mostly because punctuation is often omitted in:
- newspaper headlines
- online job listings
- advertisements
- social media posts
- informal notes
For example, you may see:
- 5 years experience required
In polished writing, this should normally be written as:
- 5 years of experience required
or
- 5 years’ experience required
Both versions are correct and much more professional.
Grammar Rules Behind Years of Experience or Years’ Experience
Understanding the grammar makes it much easier to remember which phrase to use.
Both years of experience and years’ experience are grammatically correct. The difference is in the sentence structure.Years of Experience or Years Experience.
- Years of experience uses the preposition of to connect the time period with the noun experience.
- Years’ experience uses the plural possessive form, meaning the experience belongs to or has been gained during those years.
For example:
- ✔ She has eight years of experience in teaching.
- ✔ She has eight years’ experience in teaching.
Both sentences have the same meaning.
However, this version is incorrect:
- ✘ She has eight years experience in teaching.Years of Experience or Years Experience.
The apostrophe is missing, making the phrase grammatically incomplete.
