An intern is somebody who works in a job for a short time so as to train while working, unlike just working which offers little to no training. Students learn the theory of their study at school but practice the work at an organisation or company. Generally an internship is unpaid or the organisation concerned provides a compentation. This depends on the level and knowledge of the student. Students with extra talent capability may be paid some times and scholarship students may be hired sometimes for work by various museums and institutions. But students eager to work may also help at their cost.
