At Korba Prep School, pupils are aged between 12 and 16 years. They study for three successive years: 7th, 8th and 9th form. AT the end of the last year, the students have the choice to sit for an optional national exam. Successful ones are allowed to attend elite schools known as Pilot schools. The others go to normal secondary schools. At the age of 12, the students also have another choice. They can choose to attend vocational school known in Tunisia as Technical school. In this kind of school, pupils study usual subjects and focus on learning about crafts and choosing at a later stage one of them as specialty. Once they complete 3 years at the vocational school, they choose one of the available training centers across the country and continue their training until obtaining a diploma of technician or high technician.
