About 70% of Spain's student population attends public schools or universities. The remainder attend private schools or universities, some of which are operated by the Catholic Church.
Compulsory education begins with primary school or general basic education for ages 6 - 16. It is free in public schools and in many private schools, most of which receive government subsidies. Following graduation, students attend either a secondary school offering a general high school diploma or a school of professional study in all fields law, sciences, humanities, and medicine — and the superior technical schools offer programs in engineering and architecture.
