British Schools
All British children must stay at school from the age of 5 until they are 16.
Many of them stay longer and take final examinations when they are 17 or 18. Before 1965 all children of state schools had to go through special intelligence tests. There were different types of state secondary schools and at the age of 11 children went to different schools in accordance with the results of the tests.
State schools are divided into the following types:
Grammar schools. Children who go to grammar schools are usually those who show a preference for academic subjects, although many grammar schools now also have some technical courses.
Technical schools. Some children go to technical schools. Most courses there are either commercial or technical.
Modern Schools' Boys and girls who are interested in working with their hands and learning in a practical way can go to a technical school and learn some trade.
Comprehensive schools. These schools usually combine all types of secondary education. They have physics, chemistry, biology laboratories, machine workshops for metal and woodwork and also geography, history and art departments, commercial and domestic courses.
There are also many schools which the State does not control. They are private schools. They charge fees for educating children, and many of them are boarding schools, at which pupils live during the term time.
After leaving school many young people go to colleges of further education. Those who become students at Colleges of Technology (called «Techs») come from different schools at different ages between 15 and 17. The lectures at such colleges, each an hour long, start at 9, 15 in the morning and end at 4,45 in the afternoon.
