Secondary

Secondary school is the next step up from primary school. Secondary schools are often called high schools or middle school .  A person generally starts middle school at age 11 or 12 and starts high school at age 14 or 15 and finishes at age 18. Generally a student goes to the high school for four years.

The start of lower secondary education is characterised by the transition from the single-class-teacher, who delivers all content to a cohort of pupils, to one where content is delivered by a series of subject specialists. Its educational aim is to complete provision of basic education (thereby completing the delivery of basic skills) and to lay the foundations for lifelong learning.
(Upper) secondary education starts on the completion of basic education, which also is defined as completion of lower secondary education. The educational focus is varied according to the student's interests and future direction. Education at this level is usually voluntary.
