Mirabal International School

A long-established Spanish private school in Boadilla del Monte offering bilingual education, the Spanish bachillerato and the IB Diploma.

Founded in 1982 by a cooperative of 28 teachers, on a large plot in Boadilla when the area was still small and rural. Today the school has roughly 1,900 students and 170 teachers across two locations, with bilingual Spanish-English education, a strong music programme since 1985 and one hour of daily sport. Authorised for the IB Diploma alongside the bachillerato.

PISA-style internal scores are above the Spanish average. The picture from current families is mixed: positive accounts emphasise the breadth of curriculum, sport and music inside the school day, while a recurring concern is that teacher turnover has grown and that the bilingual English level for graduating students is patchier than the marketing suggests. Suits Spanish families who want a values-led, all-round private school in the southwest Madrid belt rather than a fully international setting.

• Spanish-language parent reviews split. Long-term families on Micole.net describe satisfaction with academics, English level, sports and robotics; critical voices flag a dip in secondary and concerns about how complaints are handled by leadership.
• Aggregate sits around middling across more than 130 ratings, which reads as polarised rather than uniformly negative.
• IB Diploma coordination, including realistic predicted grades, is named by some parents as the route to international university offers.
• One Reddit thread on Spanish private schools recommended Mirabal alongside SEK Internacional for language outcomes.
• Common positive themes: teacher attentiveness in primary, food, sport and robotics. Common negatives: secondary inconsistency, response from leadership when families raise issues.
