In Australia, Year 12 is either the 12th or 13th year of compulsory education or the first or second year of post-compulsory education, depending on the state. However, one may leave school in year 10, after completing a series of compulsory tests, unless in Victoria, where no tests are required. It is the third year of "senior school", following Year 10/11 and fifth year of high school. Although there are slight variations between the states, most students in Year 12 are aged between 17 and 18.
New Zealand
In New Zealand, Year 12 is the 12th full year of compulsory education, with students entering Year 12 generally aged between 15.5 and 17. The minimum age for leaving compulsory education is 16 years of age, so for some students this is their last year of compulsory education.

It is followed by Year 13, the final year of secondary education in New Zealand.
