After grade 7, pupils must take standardised national exams to enter secondary school, which runs from eighth to 10th grade. Space in Mozambican universities is extremely limited; thus most pupils who complete pre-university school do not immediately proceed on to university studies. Many go to work as teachers or are unemployed. There are also institutes that give more vocational training, specialising in agricultural, technical or pedagogical studies, which students may attend after grade 10 in lieu of a pre-university school.
