Madrid is one of Europe's deepest markets for bilingual education. The regional Comunidad de Madrid public bilingual programme has now been running for two decades, and the city's private and international schools have built sophisticated dual-language tracks alongside the IB and British curricula. For families relocating in 2026, choosing a bilingual international school in Madrid is a real opportunity: a child can leave with academic English and academic Spanish, both at university entry standard, plus a third language. This guide explains how the bilingual landscape works, the schools families most often shortlist, fee ranges and what to ask on a visit.
How bilingual programmes work in Madrid
International schools in Madrid combine bilingualism in three different ways.
The first model is dual-credential bilingual, where children study a single integrated programme that delivers both the Spanish national curriculum (LOMLOE) and an international qualification (IB Diploma, IGCSE/A Level or American high school diploma). Around half of subjects are taught in English, half in Spanish across primary and secondary. The second model is English-medium with serious Spanish, where instruction is in English but Spanish is taught daily as a working language and used for some subjects (often Social Sciences in Bachillerato). The third model is Spanish-medium with strong English, used by some Spanish private schools that have built up their English programme to dual-language depth.

Bilingual school fees in Madrid (2026)
Bilingual programmes carry essentially the same headline fees as the standard track at most international schools in Madrid. Realistic 2026 ranges per academic year are:
Early Years (P3 to P5): around €7,000 to €13,000. Primary (Years 1-6): around €9,000 to €17,000. ESO and Bachillerato / IGCSE and A Level (ages 12-18): around €11,000 to €23,000, with the IB Diploma at the upper end. Enrolment fees of €1,000 to €3,000 per child, plus lunch (€1,500-€2,000), school bus (€1,500-€3,000) and uniform (€250-€500) are typically billed separately.
Practical tips for choosing a bilingual school in Madrid
Test the depth, not the title. Many Madrid schools advertise themselves as bilingual but deliver as little as two hours of English per day. For genuine bilingual outcomes by age 11, children typically need at least 35-50 per cent of weekly instruction in the second language during primary years. Ask the school for a published weekly hours-by-language breakdown by year group.
Check the dual qualification path. If your child plans to apply to universities in Spain, the Bachillerato grade is what counts on the EvAU exam. If applying abroad, IB Diploma or A Levels are usually preferred. Ask whether your shortlisted school offers a true dual-credential pathway or only one of the two routes.
Match location to your housing plan. Madrid's bilingual international schools cluster around the north (Aravaca, La Moraleja, Las Rozas, Pozuelo) and the centre. Commute traffic on the M-40 and A-6 in the morning is heavy, so picking the right "school zone" is often the first big housing decision.
