The ‘efterskole’ is a unique Danish independent and residential school for young people between 14 and 18 years of age. Currently, more than 28,000 students attend one of the approximately 250 schools spread across Denmark, and the schools are also open to students from abroad. Historically and culturally, the efterskole is related to the Danish free school movement, and the efterskole is often regarded as a junior form of the Danish folkehøjskole (folk high school), closely related to the educational ideas of N.F.S. Grundtvig (1783-1872), who wanted schools to provide enlightenment for life rather than formal vocational training.
