The document summarizes proposed changes to the curriculum in England across different key stages (KS3, KS4, KS5). Some of the key changes include making GCSE and A-Level courses linear with final exams only, reforming vocational qualifications, and raising the participation age to 18 by 2015. Schools will have more flexibility in their curriculum at KS3 for a transitional period, and the new national curriculum being introduced in 2014 will focus more on knowledge than skills. Performance measures for schools will also be reformed based on English/maths pass rates and student progress scores.
