Eleventh grade
Eleventh grade (called Grade 11 in some regions) is the eleventh, and for some countries final, grade of secondary schools. Students are typically 16 or 17 years of age, depending on the country and the students' birthdays.
Australia
In Australia, Year Eleven is typically the twelfth year of education and fifth (except Queensland, Western Australia and South Australia, which it is the fourth) year of high school education. Although there are slight variations between the states, most students in Year Eleven are aged between sixteen and seventeen. Queensland year-eleven students are the youngest in the country, as they usually enter at age fifteen.
In New South Wales, Year Eleven is the shortest year as it only lasts three whole terms. Year Twelve begins its first term where Year Eleven would have its fourth.
Year Eleven is followed by Year Twelve, the final year of high school education (unless students chose to undertake the optional Year Thirteen).
Belgium
In Belgium, the 11th grade is called 5ème secondaire in the French speaking part of the country, and "5de middelbaar" in the Dutch speaking part.
