Vocational secondary education in Denmark takes place at special state-funded vocational schools (erhvervsskoler), most of which are either technical schools or business colleges (handelsskoler). The creation of vocational training began as early as the 1400s, but wasn't fully established until 1875 when Denmark passed legislation that would allow for the use of government grants towards technical and training schools. Vocational training schools are jointly run by business and trade associations, such as unions who hope to create a form of stream-lined training into the labour force. Through a combination of teaching in vocational schools and apprenticeship, mostly in private companies, students are trained for work in eight specific fields which include: construction, commerce, metal, agriculture, transportation, food, service, and media.
