Chesham Grammar School

Chesham Grammar School (CGS) is an outstanding, co-educational grammar school of over 1200 students, just under 400 of whom are in the Sixth Form. Our students achieve highly at both GCSE and A level and the vast majority move onto university, with a number each year gaining entry to Oxford and Cambridge. 

We are immensely proud of the students we produce who not only achieve outstanding results but who also display the habits of successful learners and who are well equipped to cope with the demands of 21st century life.

CGS is a rewarding and stimulating environment in which to work and we are delighted to be part of the Astra Learning Alliance, working in partnership with other local schools to help train the next generation of teachers.
