GCSE's are the main qualifications that your child will take in Key Stage 4. They are designed to be studied over two years in Years 10 and 11. Some schools encourage students to study certain GCSE's in one year, taking the exams at the end of Year 10.

The GCSE (General Certificate of Secondary Education) program in the United Kingdom is a two-year course that spans both Year 10 and Year 11. Most students in England, Wales, and Northern Ireland begin their specific GCSE subject studies at age 14 (Year 10) and complete their final examinations at age 16 at the end of Year 11. This two-year period is known as "Key Stage 4." During Year 10, the focus is on covering the core curriculum and starting coursework or "controlled assessments" in various subjects. Year 11 is typically dedicated to finishing the syllabus and intensive revision leading up to the national exams in May and June. While the standard path is two years, some schools offer "fast-track" options where certain subjects are completed in a single year, and some students may start certain "foundation" elements in Year 9. The results of these exams, usually released in August, are critical as they determine a student's eligibility for further education, such as A-Levels, T-Levels, or apprenticeships. In short, Year 10 is the "learning" year and Year 11 is the "examination" year of the GCSE journey.
