The UK National Curriculum – Secondary

The next two important phases in the after primary education comes the secondary school phase. 

They are broken down into: Key Stage 3 - Years 7 to 9 - for pupils aged between 12 and 14 years old, and
Key Stage 4 - Years 10 to 11 - for pupils aged between 15 and 16 years old.

Key Stage 3 is a very crucial stage in your student’s education, setting them up with the needed knowledge and skills to face the major General Certificate of Secondary Education (GCSE) GCSEs in Key Stage 4. During Key Stage 3, the student will take a more specified approach to subject areas, continuing with core subjects from Key Stage 2. Regular parent teachers meeting are set up to allow the parent to understand the progress of the child and also allowing them to support the child in their education. End 

Key Stage 4 is the last compulsory stage in your child’s education, covering ages 14-16, the final two years of secondary education. During key stage 4 most pupils work towards national qualifications - usually GCSEs.

The compulsory national curriculum subjects are the ‘core’ and ‘foundation’ subjects.
Core subjects are: English, Maths and Science
Foundation subjects are: Computing, Physical education, Citizenship
Schools must also offer at least one subject from each of these areas:
Arts, design and technology, humanities which include geography, history among others and
modern foreign languages. 

The student then comes out with the GCSE certificate which is allows them to proceed on with other options in their like, which can include further education to career paths.
