Compulsory Education Age
6–17 years old
As regulated by Article 76 of the Constitution, the compulsory nature of schooling extends throughout basic education. With regard to secondary education, the State is obliged only to promote it.
In the same sense, Articles 29 and 32 of the General Law of Education make reference to the compulsory nature of basic school education, including preschool within said obligation.
Articles 14 and 129 place parents as the natural and primary agents of education, with Article 129 recognizing the right of parents to “choose for their children the educational institution whose orientation responds to their philosophical, ethical or religious convictions”.
Finally, in relation to the obligations of the parents, Article 130 (among others) establishes that the children or minors under their tutelage must receive compulsory basic education.
