What Is an Intern? A Clear Definition, Duties, and Pay Rules

An intern takes part in a temporary role that combines work with structured learning and professional development. Interns may contribute to real projects, but the role should also provide supervision, feedback, and opportunities to build skills rather than simply fill an ongoing staffing need. Internships can be paid or unpaid and may be part time or full time during a school term or another defined period. In the United States, whether an unpaid intern must receive wages depends on the facts of the arrangement and applicable wage rules, not on the title or the intern’s agreement to work without pay. International students may also need to meet work-authorization and school requirements before starting.

What Does an Intern Do?

An intern contributes to an organization while learning how a particular field, role, or workplace operates. Typical work may include supporting a team project, researching a topic, organizing information, attending meetings, preparing drafts or presentations, and learning workplace tools and processes. A supervisor or mentor should help the intern understand the work and provide feedback.

The specific tasks matter less than the overall design of the role. A strong internship program gives the intern meaningful assignments and explains how those assignments connect to the team’s goals. For example, a marketing intern might help prepare campaign materials while learning how the team identifies an audience and measures results. An information technology intern might assist with documentation or testing while learning how the team handles its work. In both cases, the assignments can contribute to the organization while building skills the intern can use later.

How Is an Intern Different from an Employee?

An employee is generally hired to perform work the organization needs on an ongoing basis and receives compensation for that work. An internship is usually temporary and designed around training, supervision, and professional development. Interns can still do important work, but a learning-focused title does not by itself make the role different from an ordinary job.

An internship should not simply replace regular staff or give an intern an employee’s full workload without appropriate structure and pay. Entry-level employees may receive substantial training too, but they are hired into regular roles that serve the employer’s operations. An intern participates in a defined educational or career-development experience.

Are Interns Paid?

Many internships are paid, and paid opportunities can make professional experience more accessible to people who cannot afford to work without income. Some internships may be unpaid in limited circumstances. In the United States, the legal question is whether the intern is an employee under the Fair Labor Standards Act, not what the organization calls the role or whether the intern agreed to receive no pay.

The U.S. Department of Labor describes a flexible “primary beneficiary test” for evaluating whether an intern or student is an employee. The analysis considers the whole relationship and whether the intern or the employer is the primary beneficiary. Relevant factors include whether both sides understand that the internship is unpaid, whether the training resembles an educational setting, and whether the internship connects to coursework or academic credit.

The analysis also considers whether the schedule accommodates academic commitments and whether the program lasts only as long as its learning benefits. It examines whether the intern complements rather than displaces paid employees and whether both sides understand that the internship does not guarantee a job afterward. These factors are not a checklist or a count that guarantees a result. The Department of Labor explains the framework in Fact Sheet #71. For more detail, see the rules on intern pay.

What Makes an Internship Valuable?

A valuable internship helps people test career interests, build confidence, and understand workplace expectations. It should include clear learning goals so the intern knows what skills or knowledge they are expected to develop. Goals also give the intern and supervisor a way to discuss progress.

Supervision makes those goals practical. A supervisor should answer questions, explain how assignments relate to the team’s work, and give feedback that identifies what went well and what the intern can improve. For example, an intern asked to summarize customer feedback learns more when the supervisor explains how the team will use the summary in a product decision. That context turns a task into a chance to understand the work behind it.

Internships also provide exposure to workplace communication, meetings, deadlines, and professional relationships. Regular opportunities to reflect on the experience can help an intern decide whether to pursue similar work in the future.

What Should You Ask Before Accepting an Internship?

Before accepting a role, find out what the work involves and how the program supports learning. Ask what projects and responsibilities you will have, who will supervise you, and how often you will meet. Clarify which skills you are expected to build and how your performance will be evaluated. These are among the questions to ask before accepting a job.

Confirm whether the internship is paid and how payment will be handled. Ask about academic credit, expected hours, location, and duration. Clear answers can show whether the program is organized and whether the employer has considered the intern’s experience. Vague promises of “exposure” without defined work, supervision, or learning goals are a reason to ask follow-up questions.

If the arrangement includes a stipend, its tax treatment may depend on the circumstances. Learn more about what a stipend is and review the existing article on how stipends are taxed.

What Should International Students Know?

International students should not assume an internship is permitted simply because it is unpaid or related to school. Work-authorization requirements can depend on immigration status and the nature of the role. USCIS explains that a student may work as a volunteer or unpaid intern when the arrangement does not violate labor laws, relates to the student’s program of study, and meets applicable requirements.

Review the relevant USCIS guidance on practical training and confirm the requirements that apply to your status with your designated school official before starting.

How Do Internships Fit into Contingent Workforce Management?

Because internships are generally temporary, an organization may manage them alongside other short-term roles in its contingent workforce planning. This connection to workforce management does not change the central questions: whether the intern is receiving a genuine learning experience and whether the role meets applicable pay and work-authorization requirements. Clear responsibilities and supervision help an organization support interns while keeping the temporary role distinct from an ongoing employee position.
