Curriculum Intent75 test

Broad and balanced

At Chesham Grammar School, we have devised an ambitious curriculum that provides a broad and balanced education for all students.  Our provision at each Key Stage ensures that students are fully prepared for the next stage of their education or lives.


Our aim is for students to develop a deep and rich subject knowledge across the curriculum.  Teachers immerse students in their subjects and challenge them to think deeply.


We also intend to enable out students to develop the habits of the CGS Learner so that they are fully prepared for further study, the world of work and to become active citizens who make a positive contribution to society.

Personal development

Students are exposed to a wide, rich set of curriculum experiences outside of the classroom so that they are equipped with the cultural capital that they need to succeed in life.

Key Stage 3

The Key Stage 3 curriculum provides a broad and challenging programme that ensures that students build a firm foundation of skills and knowledge so that they are ready for Year 10.

Subjects studied comprise of English, Mathematics, Science (Biology, Chemistry, Physics), French and German or Spanish. History, Geography, PRE, Technology (Engineering, Food Technology and Textiles), Computer Science, Creative Arts (Music, Drama, Art), PE.  Our personal development programme is taught through Critical Thinking (Year 7 only) and Life Skills.

All lessons are delivered by well-qualified subject specialists.

Key Stage 4

At GCSE, students continue to follow a broad and balanced curriculum that prepares them for their chosen post-16 pathway - either A levels, further education and/or employment. 

All students take 6 core subjects – English Language and Literature, Mathematics, Biology, Chemistry, Physics. 

Students are then able to choose four other subjects. which must include a Language (French, German, Spanish) and a Humanity (Geography, History, PRE, Economics).  In order to encourage students to follow a broad and balanced curriculum, we strongly recommend that students choose a creative subject as their 3rd option.  The 4th subject is therefore a free choice for students.

Our Life Skills and PE programme continues at Key Stage 4.  In addition, all students continue to have one PRE lesson over a two week period.

Sixth Form

At Key Stage 5, students follow a curriculum path that intends to develop academic excellence in students, as well as skills of leadership and independent thinking, preparing them for life beyond CGS.

Students choose to study either three or four subjects at A level and are given the opportunity to take the Extended Project Qualification. All students follow a programme of non-examination Sixth Form Studies including PE, the lecture programme, volunteering, work experience and much more.
