The KS4 curriculum provides students with opportunities to build on their learning experiences gained during Key Stage 3.

The aims and objectives of the KS4 curriculum are to enable students to develop fluent knowledge, skills and understanding of mathematical methods and concepts; acquire, select and apply mathematical techniques to solve problems; reason mathematically, make deductions and inferences, and draw conclusions; and comprehend, interpret and communicate mathematical information in a variety of forms appropriate to the information and context.

Transferable skills enable young people to face the demands of further and higher education, as well as the demands of the workplace, and are important in the teaching and learning of our curriculum. Our curriculum aims to develop students’ cognitive skills (non-routine problem solving, expert thinking, metacognition, creativity), systems thinking (decision making and reasoning) and their critical thinking (cognitive skills such as analysing, synthesising and reasoning skills). At same time we seek to improve students’ interpersonal skills (active listening, oral communication, written communication, assertive communication and non-verbal communication) and their capacity for collaborative problem solving (teamwork, establishing and maintaining shared understanding, taking appropriate action, establishing and maintaining team organisation).

As a school we follow the Edexcel GCSE 9-1 specification which is aligned with the DfE KS4 Mathematics Programme of Study. Themes covered are:
