what is 6th form in england

In England, sixth form refers to the final two years of secondary education, typically for students aged 16 to 18. It is not compulsory, but university entrance normally requires at least three A-level qualifications and perhaps one AS level. Sixth form is where young people can study A-levels and sometimes vocational qualifications after they have finished their formal education at the end of year 11. Sixth form can be attended in a state school or a private one, and most schools divide sixth form into Lower Sixth and Upper Sixth, which can also be abbreviated to L6 and U6. The term "sixth form" comes from the historical practice of schools having five forms or grades, with the sixth form being added for students in their final two years of secondary education.
