The King's School, Canterbury is an independent, co-educational secondary school. There are currently 791 pupils on the school roll(名单). The School has a long and distinguished history, and it is also one of the oldest charities in the country, providing scholarships to pupils and organizing a Charity of the Term.

The curriculum(课程)at King’s is based on strong academic roots. It emphasizes and relies upon what is best in traditional independent school education: scholarly excellence supported by a caring and tutorial system, and a wide-ranging co-curricular programme. However, it is continually adapting and reacting to the changing demands of modern education: new subjects are added, new teaching techniques adopted, and there is an increasing awareness of the need to provide programmes of study that match individual needs and skills.

The curriculum is divided into three units: the Lower School (Year 9), an introductory year; the Middle School (Years 10 and 11), working to GCSEs; and the Sixth Form ( Years 12 and 13), taking AS and A levels.  

Full details can be found in:  Shell Guide and Handbook; Middle School Academic Guide 2009-11; Middle School Academic Guide 2010-12;  Sixth Form Guide 2009-11 and Sixth Form Guide 2010-12.

Formal and structured educational support, for those who need it, is available at all levels. The well-stocked Library is open 7 days and 6 evenings per week. ICT facilities (including the Internet) are available for all and the whole school (studies within the Houses as well as classrooms) is extensively networked.   

Pupils are offered extensive careers advice throughout their time at King’s. Almost all go to university, either immediately or following a GAP year.  The most popular university destinations are Cambridge, Bristol, Nottingham, Durham, Leeds, Oxford, Edinburgh, Manchester, and University College, London.
