Year 6 is an educational year group in schools in many countries including England, Wales, Australia and New Zealand. It is usually the sixth year of compulsory education and incorporates students aged between ten and twelve.
In Australia, Year 6 is usually the sixth year of compulsory education. Although there are slight variations between the states, most children in Year Six are aged between eleven and twelve. Unlike in many UK schools, in Queensland a year six will carry on in 'primary' school throughout year seven and then will go to 'high' school in Year 8 in Key Stage 3. 
In New Zealand, Year 6 is the sixth year of compulsory education. Children entering this year group are generally aged between 9.5 and 11.  Year 6 pupils are usually educated in primary schools or in area schools. For contributing primary schools, this is the last year, with students moving onto intermediate schools or combined intermediate and secondary schools, while full primary schools continue to Year 8.
In schools in England Year 6 is the sixth year after Reception. It is the sixth full year of compulsory education, with children being admitted who are aged 10 by 1 September in any given academic year. It is also the final year of Key Stage 2 in which the National Curriculum is taught. It is also the year in which all students in maintained schools undertake National Curriculum tests (known as SATs) in the core subjects of English and Mathematics.
In some parts of England, where there remain separate Grammar and Secondary modern schools, students in Year 6 may sit a test for entrance into a Grammar school. The test is known colloquially as the Eleven plus exam.
In schools in Wales Year 6 is the sixth year after Reception. It is currently the sixth full year of compulsory education, with children being admitted who are aged 10 on 1 September in any given academic year. It is the final year group in Key Stage 2.
