Key Stage (KS) 4 is the stage of the National Curriculum between the ages of 14 and 16 years. GCSE (General Certificate of Secondary Education) is the principal means of assessing pupil attainment at the end of compulsory secondary education. Grades A* to G are classified as passes, grades A* to C as good passes and grades U and X as fails. This indicator relates to pupils achieving 5A*-C grades or equivalent including GCSE English and Maths taken at the end of KS4.
