Secondary school (the term "high school" is most often associated with in English-speaking countries, though the two are far from synonymous) is a term used to describe an educational institution where the final stage of schooling, known as secondary education and usually compulsory up to a specified age, takes place. It follows elementary or primary education, and may be followed by university (tertiary) education.
There are many different types of secondary school, and the terminology used varies around the world. Children usually transfer to secondary school between the ages of 10 and 16 years, and finish between the ages of 16 and 19 years, though there is considerable variation from country to country.
The following descriptions and definitions pertain to state-funded education unless otherwise stated.
