Internship is a system of on-the-job training for white-collar and professional careers. Internships for professional careers are similar to apprenticeships for trade and vocational jobs. Although interns are typically college or university students, they can also be high school students or post-graduate adults. Rarely, they can even be middle school or in some cases elementary students.

Generally, the internship works as an exchange of services for experience between the student and his or her employer. Students exchange their cheap or free labor to gain experience in a particular field. They can also use an internship to determine if they have an interest in a particular career, create a network of contacts, or gain school credit. Some interns also find permanent, paid employment with the companies in which they interned. Thus, employers also benefit as experienced interns need little or no training when they begin full-time regular employment.

Internships exist in a wide variety of various industries and settings. An internship may be paid, unpaid or partially paid (in the form of a stipend). Paid internships are common in professional fields including medical, architecture, science, engineering, law, business (especially accounting and finance), technology and advertising fields. Non-profit charities and think tanks have unpaid, volunteer positions. Internships may be part-time or full-time - typically they are part-time during the university year and full-time in the summer. They usually last 6–12 weeks, but can be shorter or longer, depending on the company involved. The act of job shadowing may also constitute interning.
