Secondary education in Argentina is called ''Polimodal'' (having multiple modes) since it allows the student to choose their orientation. Polimodal is usually 3 years of schooling, although some schools have a fourth year. Before entering the first year of polimodal, students choose an orientation from the following five specializations: ''Humanities and Social Sciences'', ''Economics and Management of Organizations'','' Art and Design'', ''Health and Sport'' and ''Biology and Natural Sciences''.
