These schools are often managed by non-profit organisations but are under the supervision and responsibility of local authorities. In addition, there are vocational schools under the authority of the Ministry of Industry, Trade and Labour that teach “traditional” trades, such as vehicle maintenance and construction for the equivalent of Grades 9 to 12. The sector is relatively small, with about 13 500 students in around 70 institutions, equivalent to only 3% of the total number of Grade 9 to 12 students.
