Student exchange, youth exchange or high school exchange is applied to the age group of 15 to 19 and refers to extended stays of students of one country with families in another country, such as under the supervision of organizations like Youth for Understanding and American Field Service. Regular high schools are usually attended during these stays.
These exchanges have become popular after World War II and aim at developing a better understanding and tolerance between the cultures. Recent studies show that this effect can be proven.
