Usually children go to a primary school at the age of five and stay there until they are eleven. If pupils study at schools of the comprehensive system they go to the middle or upper school without any examinations. They may leave school at the age of 16or may stay for a year longer to get ready for their futher education. If they go to schools of the selective system at the age of 11 they sit the 11-plus examination. Those who are successful go to a grammar school, where they trained for a job and receive a less academic aducation. The private system is very expensive. Only 7 percent of children go to private schools. And the level of education in such schools is much better.
