A secondary school, often referred to as a high school or a senior high school, is a school which provides secondary education, between the ages of 11 and 19 depending on location, after primary school and before higher education.
In Nigeria, secondary school starts from JSS1(7th grade) until SSS3(12th grade). Most students start at the age of 10 or 11 and finish at 17 or 18. Students are required to sit for the West African Senior Secondary Certificate Examination (WASSCE). To progress to university students must obtain at least a credit in Maths, English and three other subjects in WASSCE.
In Somalia, secondary school starts from 9th grade until 12th. Students start it when they are around 14 to 15 years of age and finish at 18. Students are required to study Somali and Arabic, with the option of either English or Italian depending on the type of school. Religion, chemistry, physics, biology, physical education, textile, art, design, and music are also typically available. When secondary school has been completed, students are sent to national training camp before going to either college, or military training. Similar to other institutes around the world, the age of pupils can vary as some students may be required to repeat a previous year if they have not achieved their academic potential, or may be allowed to skip a year if their level of achievement is higher than the grade level.
In South Africa, high school begins at grade 8. Students study for five years, at the end of which they write a Matriculation examination.
As of 2008, students sit the National Senior Certificate examinations, which replaced the Senior Certificate and Further Education and Training Certificate. To progress on to university, students must attain a pass in their Home Language, an Additional Language, Mathematics or Mathematical Literacy, and Life Orientation, as well as at least three electives; see further under National Senior Certificate. (The system previously allowed for an examination at the Higher or Standard grade for each subject. Since 2008, this has been discontinued.)
