THIS year's global university rankings includes 12 Spanish colleges in the top 50, a major improvement on the 2017 edition.
The QS Subject Rankings list considers universities by subject, and the dozen in Spain which feature are highlighted for 22 different faculties.
Ranking is decided through factors such as results of major surveys by employers and academics, and data relating to research carried out in the universities.
This year's list by the company QS (Quacquarelli Symonds) has analysed 46 specialist subjects within six main areas: arts and humanities; engineering and technology; health and medical sciences; natural sciences; social sciences, and business administration.
