IELTS Requirement for Spain Universities: Minimum Score

Typical minimum: 5.5 to 6.5 overall for CEFR B2, the level most English-taught bachelor and master programmes ask for; some programmes ask for C1 (IELTS 7 to 8) instead.

Confirmed on official certificate-equivalence tables published by several universities researched for content/inbox/universities-es.json: Universidad Autonoma de Madrid's own table, the Consell Interuniversitari de Catalunya's table used by the Catalan public universities (Universitat de Barcelona, Universitat Autonoma de Barcelona, Universitat Politecnica de Catalunya), the Andalusian public universities' shared table (Universidad de Granada, Universidad de Sevilla), and Universidad Complutense de Madrid's own table all set B2 at IELTS 5.5 to 6.5. This is a national and regional convention (often citing CRUE, the Spanish rectors' conference, or a regional inter-university council) rather than one central government figure, so it is recorded here as the typical minimum across the universities checked rather than as a single official national number.
