Bilingual Boarding Schools in Spain, Italy, and Portugal
A bilingual boarding school keeps the curriculum in English (IB or British), but places the student in a country where the local language becomes a second academic language and everyday reality. The young person studies Science in English and, after class, talks with local staff, explores the city, and builds fluency in Spanish, Italian, or Portuguese in a natural way. This guide explains how the model works, why Spain, Italy, and Portugal sit in Be Easy's curation, and which partner schools join this project.
What defines a bilingual boarding school?
In a monolingual British or American boarding school, English dominates every space: classes, dorms, activities, and staff. The student earns a strong credential, but leaves with one consolidated language.
In a bilingual boarding school, the curriculum stays in English (IB Diploma, IGCSE, or A-Levels), but the outside environment drives acquisition of the local language. Spanish, Italian, or Portuguese stops being just a subject and becomes the language of the market, the restaurant, excursions, and friendships beyond campus.
Families choose this format when they want two outcomes at once:
- A global university credential (IB or British) recognized by universities in Europe, North America, and Oceania
- Functional fluency in a second European language, gained through real immersion, not an extra class
The IB Diploma allows Literature in more than 60 languages, which means Spanish or Italian studied at the boarding school can sit inside the official curriculum, not as a side activity.
What advantages do Spain, Italy, and Portugal offer?
| Country | Immersion language | Reference school system | Curricula at Be Easy partners |
|---|---|---|---|
| Spain | Spanish | LOE/LOMLOE, ages 10-18, via Ministerio de Educacion | IB Continuum, IGCSE, A-Levels, American curriculum |
| Italy | Italian | Istruzione secondaria superiore, ages 14-19, via MIUR | IB Continuum (Early Years to DP) |
| Portugal | Portuguese | Secondary education, grades 10-12, via DGE | Cambridge IGCSE, A-Levels, IB Diploma |
Spain
Spanish is the second most spoken language in the world by number of native speakers, according to the Instituto Cervantes. For a student planning a career across the Americas, Europe, or the global job market, Spanish fluency has direct resume value. High school in Spain combines a consolidated system with a cost of living below the Western European average, according to Numbeo.
Italy
Milan hosts the largest bilingual IB boarding school in Be Easy's curation. Immersion happens outside campus: Italian is the language of excursions, museums, local shops, and historic cities woven into the curriculum. High school in Italy shows how the local system runs alongside the international curriculum offered by IB schools.
Portugal
Portugal offers a lower cost of living than Spain or Italy in major capitals, according to Numbeo. The D4 visa, issued via AIMA, is the path for international students. Lisbon and the Setubal region combine Atlantic access, historic heritage, and regular air links to South America and Europe.
Which bilingual boarding schools are in Be Easy's curation?
International School San Patricio Toledo
The International School San Patricio Toledo is the only school with a full IB Continuum (PYP, MYP, and DP) in Toledo, a UNESCO World Heritage site since 1986. The multilingual program covers English, Spanish, French, and German up to age 16. Literature in the IB Diploma is available in more than 60 languages, and the campus spans 30,000 m2 in the historic heart of the city.
King's College Soto de Vinuelas
King's College Soto de Vinuelas is the highest-rated British boarding option in Spain. In the 2023/24 session, IB Diploma students reached an average of 36 points, above the global average of 30.58 (IB Statistical Bulletin, May 2025), and 48.5% of A-Level students earned A and A* grades. Tenbury House hosts boarders from more than 50 nationalities in Tres Cantos, 20 km from central Madrid.
Sotogrande International School
Sotogrande International School, in Cadiz, recorded a 100% IB Diploma pass rate in 2023, with an average of 34 points, four above the global mean. Templeton House houses more than 160 boarders with private bathrooms. Golf, sailing, and polo are integrated into the Sotogrande resort in Andalusia.
International School of Milan
The International School of Milan operates on Italy's largest school campus and ranks among the world's Top 5 IB schools by results. Boarding has only 42 residential places, which supports individualized attention. Fortnightly excursions to Verona, Bologna, Rome, Florence, and Venice sit in the calendar and make Italian a weekly living language.
St Peter's International School
St Peter's International School, in Palmela, combines Cambridge IGCSE with the IB Diploma in the final two years, with Portuguese as a daily second language. The campus sits in the Setubal District, with direct access to Arrabida Natural Park. Lisbon is 30 to 40 minutes away; Ericeira, Europe's only World Surf Reserve, is under an hour.
King's College School Cascais
King's College School Cascais opened boarding in September 2025 with 50 residential places for students aged 13 to 18. It belongs to Inspired Education (121 schools in 28 countries) and offers a full British curriculum (IGCSE + A-Levels) with an IB Diploma option. The 40,000 m2 campus is 10 minutes from the Atlantic, 30 minutes from Lisbon by train, and 20 minutes from Sintra, a UNESCO World Heritage site.
How do curriculum and applications work?
The three Spanish bilingual boarding schools offer distinct paths: a full IB Continuum, the British curriculum (IGCSE + A-Levels), and, at Sotogrande, also an American curriculum. The difference between the British system and the IB sits in assessment structure: A-Levels require specialization in 3 or 4 subjects; the IB keeps six subjects plus TOK, EE, and CAS.
The application process follows four stages common to all six partners:
- School records: grades from the last two years and, when applicable, predicted grades from current teachers
- Entrance test: English, reasoning, and math (format varies by school)
- Interview: held online for international applicants
- Visa: long-stay via the Spanish consulate for Spain; study visa via the Italian consulate for Italy; D4 visa via AIMA for Portugal
Boarding school daily life includes integrated tutoring, sports and cultural activities, and daily academic support that helps IB performance compared with day schools alone.
Frequently asked questions about bilingual boarding schools
Does the school's bilingual model count as an extra language in the IB Diploma?
Yes. The IB Diploma includes the Language Acquisition group, where Spanish, Italian, or Portuguese can be taken as Language B and contribute to the final Diploma score, adding value to university applications.
What is the difference between a bilingual boarding school and a typical international school?
Bilingual boarding offers immersion in two directions: the curriculum stays in English, but life outside the classroom happens in the country's language, without the language bubble that isolates students in international schools set in closed communities.
Which visas are required to study at these schools?
Spain: long-stay visa via the Spanish consulate. Italy: study visa via the Italian consulate. Portugal: D4 visa via AIMA or the Portuguese consulate in the home country.
Is the IB Diploma average the same at these schools and at British schools?
No. The global IB average was 30.58 points in the May 2025 session, according to the IB Statistical Bulletin. King's College Soto de Vinuelas recorded an average of 36 in 2023/24, and Sotogrande reached 34 points with a 100% pass rate in 2023.
How far in advance should families start the process?
The ideal is to start 12 to 18 months before the first curriculum year. Schools with small boarding capacity, such as ISM with 42 residential places, often close applications well before the academic year begins.
