An internship is a temporary, supervised position where a student or recent graduate does real work in a field to learn it. It runs for a set period, usually a summer or a semester. Many are paid, some are unpaid or for credit, and they can be in person, remote or hybrid. Learning is the point, which separates it from a regular job.
Everyone around you seems to be "looking for an internship," and at some point it's fair to stop and ask what one actually is. Is it a job? Do you get paid? Do you need one? How is it different from a co-op or an apprenticeship?
Here's the plain version, then the details.
What is an internship?
An internship is a short, supervised stretch of real work in a field you want to learn. You join a company, nonprofit, lab or government office for a set period, usually a summer or a semester, and you work on real tasks with someone more experienced checking in on you.
Two things make it an internship and not just a job:
- It has an end date. You're there for a defined stretch, not indefinitely.
- It's built around learning. The point is for you to come out knowing how the work is done, not only for the employer to get work out of you.
The National Association of Colleges and Employers (NACE), the professional body for college career centers and campus recruiters, puts it like this in its internship definition guide (June 2023): an internship is "a form of experiential learning that integrates knowledge and theory learned in the classroom with practical application and skills development in a professional workplace setting," whether in person, remote or hybrid.
In everyday terms: it's the bridge between what you study and what the job actually looks like.
What makes something a real internship
NACE lists the criteria an experience should meet. In plain language, a real internship has:
- Real learning. You apply what you know to real work. It isn't just there to keep the employer's operations running or to replace a regular employee.
- Skills you can take elsewhere. What you learn should be useful at other employers too.
- A defined start and end that you and the employer agree on.
- A written description of the role, with clear responsibilities and qualifications.
- Learning goals. You know what you're supposed to come out able to do.
- A real supervisor with relevant experience, who gives you feedback and the tools to do the work.
If a "role" has none of these, so no supervisor, no goals and no end date, it's worth asking what you're actually signing up for.
What do interns actually do?
It depends on the field, but a good internship gives you a real slice of the job. A few typical examples:
- Software engineering: fixing bugs, building a small feature, writing tests, and shipping code that a senior engineer reviews.
- Marketing: drafting posts and emails, pulling campaign numbers into a report, and researching competitors.
- Finance: building and checking spreadsheet models, preparing slides for a meeting, and researching companies or markets.
- Engineering: helping with designs, running tests in a lab or on a site, and documenting the results.
- Research: running experiments, cleaning data and helping write up findings.
Most internships also come with one bigger project you present at the end. That project is usually what ends up on your résumé and what you'll talk about in your next interview, so it's worth asking about in the interview for the internship itself. When you get to that interview, start with how to answer "Tell me about yourself".
Are internships paid?
Many are, some aren't, and the rules depend on who's hiring.
In the U.S., a for-profit company can only skip paying an intern if the intern, not the company, is the "primary beneficiary" of the arrangement. The Department of Labor weighs seven factors to decide that, laid out in its Fact Sheet #71. We walk through all seven in Are Unpaid Internships Legal?. Nonprofits and government offices are treated differently.
How common is pay in practice? Of the 34,058 internship, co-op and apprenticeship listings live on UTern when we checked on October 18, 2026, 24,026 (71%) state what they pay. That counts listings that say so, not an estimate of how many roles are paid, and it changes daily on our internship statistics page. To find paid roles, browse internships that state their pay. For what interns typically earn and how to ask about it, see Do Internships Pay? and how to answer "What are your salary expectations?".
How long is an internship, and when do they happen?
Most internships last one term. The posting states the exact dates, but they usually fall into one of these windows:
- Summer: the most common. Full-time, during the break between school years.
- Fall or spring: during the semester, often part-time so you can keep taking classes, or full-time if your school builds a work term into the degree.
- Winter: shorter programs over winter break, more common in some fields and countries than others.
Summer dominates. Of the listings live on UTern on October 18, 2026 that state a start term, 17,103 say Summer 2027, against 1,179 for Spring 2027, 1,103 for Winter 2027 and 338 for Fall 2027.
The timing that catches students out is when you apply. Summer programs open the fall before. Across 726 employers whose summer programs UTern has tracked for three or more recruiting cycles, the median program first appeared on October 14, months before the summer it's for. More on that in When to Apply for Summer Internships.
Types of internships
| Type | What it means |
|---|---|
| Paid | You earn an hourly wage or a fixed stipend. |
| Unpaid | No wage. Legal at for-profit companies only under the Department of Labor's primary beneficiary test. |
| For credit | Counts toward your degree, usually arranged with your school. Can be paid or unpaid. |
| In person | You work on site at the employer's office, lab or location. |
| Remote | You work from home. 969 live UTern listings were remote on October 18, 2026. |
| Hybrid | Some days on site, some at home. |
| Summer | Full-time over summer break. The biggest category by far. |
| Semester | Fall or spring, often part-time alongside classes. |
| Research | Work in a university or company lab, often with a professor or scientist. |
| High school | Shorter, simpler programs for high school students, often run by local employers, hospitals, museums or universities. |
Internship vs. job, co-op, apprenticeship and externship
These get mixed up a lot. The short version:
| Internship | Regular job | Co-op | Apprenticeship | Externship | |
|---|---|---|---|---|---|
| Main purpose | Learn a field | Do the work | Learn a field, in depth | Train for a skilled trade or occupation | See a job up close |
| Length | Usually one term | Ongoing | Often a semester or more, sometimes repeated | Varies by program and occupation | Short |
| Paid? | Often, not always | Yes | Usually | Yes, from day one | Usually not |
| Hands-on work? | Yes | Yes | Yes | Yes, plus classroom training | Mostly watching and shadowing |
| Ends with | Experience, and sometimes a return offer | No set end | Experience, often with the same employer more than once | A credential | A better sense of the job |
A few notes:
- Co-op (cooperative education) is usually a longer, full-time placement run through your university, alternating with semesters of class. We compare the two in detail in Internship vs. Co-op.
- Apprenticeship. The U.S. Department of Labor's apprenticeship fact sheet (updated March 2025) says Registered Apprenticeship programs "are jobs from day one" and that "apprentices earn wage increases as they learn and gain new skills," with a nationally recognized credential at the end. That's the clearest line between the two: an apprenticeship is a paid job that trains you into an occupation, while an internship is a shorter learning experience that may or may not be paid.
- Externship is a short job-shadowing experience. You mostly observe instead of doing the work yourself. Some schools use the word differently, especially in medicine and law, so check what yours means by it.
Is an internship a job?
Partly. A paid intern at a U.S. company is generally an employee for pay purposes, gets a paycheck, and has a manager like anyone else. But an internship has a built-in end date and exists to teach you, so it isn't a permanent position. On a résumé it counts as real work experience, and you list it under Experience like any other role.
Who can do an internship?
Mostly college students, especially from sophomore year on, but not only them. High school students, community college students, recent graduates and career changers do internships too. Plenty of programs are open to first- and second-year students. You don't need previous experience to land your first one. Here's how to get an internship with no experience.
Why internships matter
- You find out whether you actually like the work before you commit a career to it.
- You get proof. A real project you can describe in detail beats any line on a résumé that just claims a skill.
- You meet people who can vouch for you later.
- Some lead to a return offer, an offer to come back after graduation, so a good summer can turn into your first full-time job.
How to get one
- Pick a lane. A field and a rough type of role, so your search isn't everything at once.
- Start early. For summer, that means the fall before.
- Make one piece of proof. A project, a portfolio or a write-up of something you built or ran.
- Search where the listings actually are: employer career pages, your school's portal and sites that pull straight from them. Here's where to find internships.
- Apply to roles that fit, and tailor each one. Our guide to how many internships to apply to helps you find your number, and the cover letter template covers the rest.
Quick answers
What does "intern" mean? An intern is the person doing the internship. As a verb, to intern means to work as one.
Do you need experience to get an internship? No. Internships exist to give you experience. What helps is showing you can learn and do the work, through a class project, a club role or something you built.
Can you do an internship after you graduate? Yes. Many programs accept recent graduates, though some are limited to current students, so check the eligibility line on the posting.
Can you do an internship online? Yes. Remote internships are common, especially in software, marketing and design.
