My name is Mr Stone. I'm a teacher of Modern languages (French and Russian) at Hampton School, which is in Richmond upon Thames. The School has a history of nearly five centuries. At present, it remains a day school for some 950 boys between 11 and 19 years of age.

The course at Hampton School is academically demanding: all boys learn at least nine subjects: Art, Biology, Chemistry, Classical Civilisation, English language, English Literature, Economics, Drama, Geography, History, Mathematics, Information Technology, French, German, Greek, Latin, Russian, Spanish, Music, Physics, Religious Studies, Physical Education, Games.

As you see, it's not easy to study in our School, so we select students. Selection of students is based on written entrance tests, but we also interview our likely candidates. At the interview, we take into account a boy's other activities. For instance if two boys have done equally well in tests we give preference to the one who is keen on music or art or chess or sport.

The School encourages boys who are developing an i interest in the arts such as writing, playing musical instruments, singing, drama. About 200 boys do music with teachers. At our School there are regular lunchtime and evening concerts of popular music, jazz and rock music by pupils. We also we have a full Symphony Orchestra and a School Magazine for young writers.

Traditionally the favourite sports are tennis, cricket, athletics, rowing, rugby, soccer, and chess. There also active table tennis, basketball and badminton clubs. The School is fortunate to have much space for playing fields. Large parties of boys go abroad each year to ski. Some boys are keen on golf, sailing and windsurfing, too.

The uniform which the boys wear is basically a (colour) blazer and dark-grey trousers, a white shirt and a school tie. The tie and the black blazer with a school badge can be only bought in the school shop. The shop also offers school scarves, and clothes for games.

Parents are welcome to the school at any time. They help to arrange various activities, meet with teachers and provide financial help.
