In American English, college often means undergraduate higher education in general, university usually names an institution that may offer undergraduate and graduate programs, and graduate school means advanced study after a bachelor's degree. The terms overlap, and institutional names do not follow one perfectly consistent rule.
"I went to college in California."
The speaker might have attended an institution officially called a university. In ordinary American conversation, that is completely natural.
What is a college?
A college can be an independent higher-education institution, often focused on undergraduate education. It can also be a division within a larger university:
College of Engineering
College of Arts and Sciences
Some institutions called colleges offer graduate degrees, while some specialized schools and institutes award bachelor's degrees. The official name alone does not tell you every program available.
Americans also use college as a broad life-stage word:
"when I was in college"
"college students"
"paying for college"
These phrases can include students at universities.
What is a university?
A university commonly includes multiple schools or colleges and offers programs at more than one degree level. EducationUSA explains the general distinction by noting that colleges focus on undergraduate degrees while universities also offer graduate degrees, but it also says the words are often used interchangeably.
In formal writing, use the institution's official name:
"University of Example"
Do not replace college with university on a résumé simply because university sounds more prestigious in another language. The official credential and institution name are what matter.
What is graduate school?
Graduate school, often shortened to grad school, is education pursued after a bachelor's degree. It commonly includes master's and doctoral programs. EducationUSA defines a graduate student as someone who has earned a bachelor's degree and is pursuing additional education in a specific field.
"We met in grad school."
"She is applying to graduate school."
The phrase may refer to a university-wide graduate division or more generally to the experience of advanced study.
Professional school can refer to specialized advanced programs such as law or medicine. Requirements and degree structures differ by profession and institution, so it is useful to name the actual program.

Start a session →Undergraduate versus graduate
An undergraduate student is generally pursuing an associate or bachelor's degree. A graduate student is pursuing a credential above the bachelor's level, such as a master's or doctorate. In some administrative contexts, graduate or professional student is a combined category.
Be careful with the word graduate by itself. It can also mean a person who completed a program:
"She is a university graduate."
That does not necessarily mean she attended graduate school. It may mean she earned a bachelor's degree.
What might you hear at work?
"The company offers college tuition reimbursement."
The policy may include undergraduate, graduate, or certificate programs, but the everyday word college does not prove which ones qualify.
"I worked full time through grad school."
The speaker completed advanced study while employed.
"Which university did you attend?"
This asks for the institution, but someone who attended a college can answer with that college's official name.
"Our internship program recruits college juniors."
Here college broadly means undergraduate education, including universities.
"She went back to school."
The person may be attending college, graduate school, or another program. Context is necessary.
What can you say naturally?
For your education:
"I earned my bachelor's degree at a public university and my master's at a technical institute."
For benefits:
"Does tuition assistance cover graduate programs as well as undergraduate courses?"
For small talk:
"What did you study in college?"
That is common, though it assumes the person attended college. A more open question is:
"What was your path into this field?"
For recruiting or formal policy, prefer the precise level:
"Applicants must be enrolled in an accredited undergraduate program."
Recognition versus production
When Americans say college, do not automatically contrast it with university. They may be describing the entire undergraduate stage.
When you write, use precision appropriate to the situation:
- casual life stage: in college
- official institution: its full name
- degree level: undergraduate or graduate
- specific credential: associate, bachelor's, master's, doctorate, or the official professional degree
Avoid prestige assumptions
Institution names can carry social signals involving selectivity, cost, geography, and class. Avoid treating university as inherently better than college, or graduate education as the only serious professional path.
In hiring, education may be relevant, but it should not become vague prestige shorthand. Follow the role criteria and applicable policies. In small talk, allow colleagues to decide how much personal or financial context to share.
