- !Single-campus, non-selective international school without the scale of a multi-site selective system
- !No published, independently verified recent (post-2022) IB average located in public sources
- !No graded state inspection band exists in Spain, so external rating relies solely on accreditation cycles
- !Upper-bracket fees (to ~EUR 20,700/year in 2025/26 before boarding) place it beyond many budgets
- !Large enrolment (~1,580) means a bigger, busier setting than boutique alternatives
- !Detailed EAL/Spanish-support provision is not clearly published, so language onboarding needs direct confirmation
