Botswana has a 3-7-3-2 formal education structure. There are three years of pre-primary school, which has an official entry age of three. Primary school has an official entry age of six and a duration of seven grades. At the end of the cycle, students sit for the Primary School Leaving Examination (PSLE). Secondary school is divided into two cycles: lower secondary and upper secondary.
Lower secondary, which is known as Junior Secondary, consists of grades 8-10 and culminates in the Junior Certificate; upper secondary, which is known as Senior Secondary, consists of grades 11-12 and culminates in the General Certificate of Secondary (BGCSE) or the Internal General Certificate in Secondary Education (IGCSE). In addition, Botswana has multiple upper secondary vocational education tracks that last one to three years (ISCED 2011 mapping for 2014 school year).
