The private upper secondary schools have the same public grant system as the private basic schools. There are about 20 such schools, and they cater for 6% of all upper secondary school pupils. They differ from the private basic school, in that the content of their teaching is governed by the same rules as those applying to the public schools, the reason being that they both lead to the same final examination, i.e. the upper secondary school leaving examination (the "Studentereksamen").
