Welcome to Chesham Grammar School, an outstanding, co-educational school of over 1200 students.  CGS has a reputation for excellence.  We have high academic standards and superb examination results.

Almost all of our students progress to their first choice university including Oxford and Cambridge.  Our students will be the leaders of tomorrow and our aim is to ensure that they are well equipped for 21st century life.  We want them to be confident, articulate and optimistic as well as respectful, tolerant and compassionate.  Above all, we want them to be happy.

With best wishes Annmarie McNaney – Headteacher
