In New Zealand, Year 9 is the ninth year of compulsory education, and the first year of secondary education. Children entering Year Nine are generally aged between 12.5 and 14. Year Nine pupils are educated in secondary schools or area schools.
In England and Wales, Year Nine is the ninth year after Reception. It is the ninth full year of compulsory education, with children being admitted who are aged 13 before 1 September in any given academic year. It is also the year in which pupils are formally assessed against National Curriculum levels. With effect from 2009, National Curriculum Tests are no longer compulsory in this year group. Year Nine is usually the third year of Secondary school and was previously known as the 'third year' or 'third form'. Some schools in the UK (especially grammar schools and private schools) still refer to 'year 9' as 'third year'. In most schools in England and Wales, it is also the final year of Key Stage 3. Year 9 pupils are usually aged between 13 and 14 years old. Pupils usually either choose or start their options for their GCSE qualifications in Year 9.
