How to Choose an International School in Rio de Janeiro: 2026 Family Guide

Quick answer: how do you choose an international school in Rio de Janeiro? Start with the diploma you need, then the school calendar, language mix and commute. Rio offers American, British, Swiss bilingual and Christian options; Our Lady of Mercy American School pairs US and Brazilian curricula. Expect roughly R$5,000 to R$16,000 a month in tuition, depending on stage and school.

Deciding how to choose an international school in Rio de Janeiro is less about finding the single "best" school and more about matching a school to your family's plans. Rio's international schools differ sharply in what they lead to: an American high school diploma, the IB Diploma, IGCSEs, a Brazilian Ensino Médio certificate, or a combination of several of these.

They also differ in calendar, faith ethos, language balance and, crucially in this city, which side of the mountains they sit on. This guide sets out a practical decision framework, applies it to five well-known schools, and finishes with the questions worth asking on a campus visit.

Zona Sul or Barra: how geography shapes the choice

Rio draws international families through the energy sector, diplomacy, multinational offices, universities and a growing number of remote workers who want the city's lifestyle. Where those families live, and therefore where children go to school, is shaped by the massif of Tijuca that splits the city in two.

Zona Sul (Botafogo, Urca, Gávea, Leblon, Ipanema, Lagoa): the traditional expat heartland, with older apartment buildings, beaches and short distances. Our Lady of Mercy and The British School's Botafogo and Urca sites are here, and Escola Americana sits in Gávea.
Barra da Tijuca and Recreio (West Zone): newer, car-oriented neighbourhoods with gated condominiums, larger homes and more green space. SIS Swiss International School, Rio International School and The British School's Barra unit are here.

The two zones connect through tunnels and the coastal road, and the trip can take 30 minutes or well over an hour depending on traffic. In practice, very few families commute between Zona Sul and Barra every day. Choose your school zone first and your apartment second.

The pathways on offer in Rio

American curriculum and AP: Our Lady of Mercy follows a US programme with Common Core standards and a compulsory AP Capstone sequence, and Escola Americana offers an all-English American education.
British (IGCSE) and IB Diploma: The British School leads students to IGCSEs and the IB Diploma.
IB in multilingual settings: Escola Americana and SIS Swiss International School both list the IB among their programmes.
Brazilian national curriculum alongside an international one: Our Lady of Mercy, The British School and Escola Americana (through its Brazilian Diploma Program) let students earn Brazilian qualifications too, which matters for entry to Brazilian universities.
Trilingual and bilingual tracks: SIS teaches in Portuguese, English and German, with French as well across its network.

Five schools seen through the decision framework

OLM, Our Lady of Mercy American School

Our Lady of Mercy is a Catholic, non-profit school in Botafogo that runs the American and Brazilian curricula side by side, so students become fluent in English and Portuguese and can aim for universities in Brazil or abroad. Its 620 students are taught by 82 teachers, a ratio of about 8 students per teacher, and teacher turnover sits at around 6% a year. The early years follow the International Early Years Curriculum for ages 2 to 5, elementary uses project-based learning, and in grades 11 and 12 every student takes AP Seminar and AP Research through the AP Capstone programme, alongside preparation for ENEM, Brazil's national university entrance exam. The school is accredited with distinction by Cognia, students complete at least 100 hours of community service before graduating, and a Learning Resource Center supports children with special educational needs or who are still acquiring English. The profile lists a monthly cost band of $1,000 to $2,000 and a 4.0 rating from 7 reviews.

Best fit: families who want a genuinely dual pathway, keeping both US and Brazilian university doors open, in a values-led community where around 10% of students are international. Meals are prepared on campus and outside food is not allowed, which simplifies the daily routine but is worth knowing in advance if your child has dietary needs.

The British School, Rio de Janeiro

Founded in 1924, The British School is a non-profit, co-educational day school with more than 2,000 students from over 60 nationalities. It operates two units across three sites: Botafogo and Urca in the Zona Sul, and a separate unit in Barra. Teaching is in English and Portuguese, and students earn Brazilian qualifications (Ensino Fundamental and Ensino Médio) as well as IGCSEs and the IB Diploma. It holds a 5.0 rating from 5 reviews.

Best fit: families who want British and IB credentials together with Brazilian recognition. With sites on both sides of the city, it is also one of the few options that can follow you if you move between zones, although you should confirm which stages each site covers.

Escola Americana do Rio de Janeiro

EARJ has served international and Brazilian families in Gávea for more than 80 years. English is the common language and all classes are in English except the Brazilian Diploma Program requirements and Spanish and French language courses. The community spans over 30 nationalities, the school lists the IB among its programmes, and it holds a 4.2 rating from 5 reviews.

Best fit: families who want an all-English American environment in the Zona Sul, with the option of adding Brazilian credentials later through the diploma programme.

SIS Swiss International School Brazil

SIS Rio is a private day school in Barra da Tijuca and part of a network of 17 bilingual schools in Switzerland, Germany and Brazil, with more than 3,700 students in total. Instruction is in Portuguese, English and German, and the school lists the IB. Its rating is 3.7 from 3 reviews, so ask current parents for first-hand views.

Best fit: German-speaking families and anyone who wants a structured bilingual model with continuity to sister schools in Europe.

Rio International School

RIS is in Barra da Tijuca and teaches in English, with students from over 30 countries and staff from more than 10. It is an open-enrolment Christian school: students attend Bible classes and chapel, and teaching is framed by a Biblical worldview. It holds a 4.2 rating from 5 reviews.

Best fit: families in Barra who want an English-medium education with an explicit Christian ethos and a smaller-school feel.

Fees in reais and the hidden costs to plan for

Rio's international schools charge in Brazilian reais, normally in monthly instalments (mensalidades) across the school year, with a separate annual enrolment fee (matrícula). Only one of the five profiles shows a fee band, so the ranges below are rough indications of the market:

Early years: roughly R$5,000 to R$9,000 a month.
Elementary and middle school: roughly R$7,000 to R$13,000 a month.
High school, IB and AP years: roughly R$9,000 to R$16,000 a month, at the upper end in the final two years.

At around 5 to 6 reais to the US dollar, that is very roughly US$11,000 to $35,000 a year. Extras usually include:

The annual matrícula, often equal to about one monthly instalment, and sometimes a one-off new-student fee.
School transport, which is a real cost in Barra where distances are longer.
Meals and snacks, which some schools include and others bill separately.
Uniforms, books and digital platforms.
IB, AP or IGCSE exam fees and trips such as Model United Nations.
After-school activities, from robotics to capoeira, often charged per term.

Calendars and diplomas: the Brazil-specific questions

Check the calendar before you book the move. The Brazilian school year runs from February to December, while many international schools follow a northern-hemisphere year from August to June. A child arriving in August may slot straight into an international school but would land mid-year in a Brazilian one, and the reverse is true for a family arriving in January. Ask each school which calendar it follows and how it places children who switch hemispheres.

Decide whether the Brazilian diploma matters. Law 14,945 of July 2024 restructured Brazil's upper secondary stage, the Novo Ensino Médio, setting 2,400 of its 3,000 hours for general basic education and leaving the rest for elective pathways. For families combining a Brazilian certificate with the IB, an American diploma or A levels, that means the Brazilian component takes up a large share of the timetable. If your children are likely to study in Brazil, a dual-track school is valuable. If they will almost certainly study abroad, ask how much of the week goes to Brazilian requirements and whether that is optional for foreign students.

Weigh ethos and community honestly. Two of the five schools are faith-based, one Catholic and one Christian with Bible classes and chapel, while the others are secular. Ask how religion shows up day to day: chapel, religious education, service, or simply shared values. Then ask about the international share of the student body, since a school that is mostly Brazilian can be a wonderful way to integrate but feels very different from one where most children are transient.

Frequently asked questions

Do international schools in Rio de Janeiro follow the Brazilian school calendar?

Not always. The Brazilian school year runs from February to December, while many international schools in Rio follow a northern-hemisphere year from August to June. Schools that combine Brazilian and international curricula may adapt their calendar, so ask each school directly, especially if you are arriving in January or July and need to know where your child will be placed.

Can my child earn a Brazilian diploma at an international school in Rio?

Yes, at several schools. Our Lady of Mercy runs the American and Brazilian curricula side by side, The British School awards Ensino Fundamental and Ensino Médio alongside IGCSE and IB, and Escola Americana offers a Brazilian Diploma Program. A Brazilian certificate matters mainly if your child may apply to Brazilian universities through ENEM.

Is it better to live in Zona Sul or Barra da Tijuca for international schools?

It depends on the school. Our Lady of Mercy, Escola Americana and two British School sites are in the Zona Sul, while SIS, Rio International School and the British School's Barra unit are in the West Zone. Daily commuting between the two zones can exceed an hour in traffic, so most families live near their chosen school.
