Cygnaeus advocated separating schools from the supervision of the church and establishing a teacher training college. Cygnaeus's plan formed the basis for the folk school regulation, which was laid down in 1866. The Sloyd system became compulsory for boys in all rural schools (it still is all over the country-2007) and for all male teachers in teacher training institutions. Students learned about metals, about fabrication techniques, about selecting appropriate wood samples from the forests, about the care necessary for working with materials and finally the need for collaborative efforts to accomplish tasks. Sweden adopted these ideas a few years after Finland. A 'Sloyd Training School' was set up in Nääs, Sweden in the 1870s by Otto Salomon. Thousands of teachers from all over the world attended classes at Nääs. Some of the countries in which Sloyd was successfully introduced were the UK, the US, Japan, Brazil, Argentina, Cuba, and the Scandinavian countries. Currently, Sloyd is still part of the compulsory school curriculum in Finland, Sweden and Norway.
