Quick answer: how do you choose an international school in Kolkata? Decide first between IB or Cambridge, offered by a small group of schools such as Calcutta International School and The Heritage School, and an Indian board with international enrichment, offered by many more. Then match the school to your neighbourhood, because the EM Bypass and New Town corridors have very different commutes. Budget roughly 3 to 8 lakh rupees a year for international programmes.

Kolkata is India's most bookish big city, and it shows in its schools. Families moving here from abroad or from other Indian cities find fewer glossy international campuses than in Bangalore or Gurgaon, but strong academic culture, lower fees and a set of long-established institutions. Understanding how to choose an international school in Kolkata is mostly about two decisions: whether you want a truly international curriculum or an Indian board with international features, and which side of the city you can realistically commute to. This guide covers both, with schools you can verify and a realistic view of costs.
Why geography decides more than you expect
Kolkata's international schools cluster in two corridors. The first is south-east Kolkata along the Eastern Metropolitan Bypass, in Anandapur, Kasba and Mukundapur, where Calcutta International School, The Heritage School and Garden High School sit within a few kilometres of each other. The second is New Town and Rajarhat in the north-east, the planned satellite city near the airport where newer schools such as GEMS Akademia have large campuses. The historic south, around Ballygunge and Alipore, has older, prestigious Indian-board schools like Modern High School for Girls.
Traffic between these zones is slow and monsoon flooding from July to September makes it slower, so most families choose a home and school in the same corridor. Expatriates working in the Salt Lake or New Town IT sector usually school in New Town; those in the older commercial core or in south Kolkata look to the Bypass schools.
Curricula available in Kolkata

- ICSE and ISC: the traditional board of Kolkata's elite schools, including Modern High School for Girls, Garden High School and The Heritage School, with English-medium teaching and strong humanities.
- CBSE: the national board, used by Adamas International School, GEMS Akademia and Bridge International School, useful for families who may move within India.
International schools in Kolkata worth visiting
Calcutta International School
The city's oldest genuinely international school, founded in 1953 and now in Anandapur, offering Cambridge IGCSE and the IB Diploma to a mixed Indian and expatriate student body. Classes are small and university placements abroad are strong. It is the default for diplomatic and corporate expatriate families, and the most expensive school on this list.
The Heritage School
A large campus on the Bypass in Anandapur combining ICSE and ISC with the IB Diploma in the senior years, so families can start in an Indian board and move to IB at 16. Facilities, sport and co-curricular breadth are among the best in the city. Admission is competitive at the main entry points.
Garden High School
An ICSE and ISC school in Kasba with a reputation for academic rigour and unusually good arts and drama. It is a strong option for families staying several years who want a Kolkata institution rather than an international brand, and fees are moderate.
GEMS Akademia International School
Part of the GEMS Education group, on a large campus in the New Town corridor, offering CBSE alongside Cambridge programmes with boarding available. It suits families based in Salt Lake, New Town or near the airport, and is one of the few options with weekly boarding in the city.
Modern High School for Girls
One of the most sought-after girls' schools in India, in south Kolkata, following ICSE and ISC with an international section offering Cambridge and IB. Entry at the main points is highly competitive and applications for the youngest years open more than a year ahead.
Fees in Kolkata: what to budget in 2026
Fees are quoted in rupees, usually per quarter or per month, and are lower than in India's other metros for equivalent programmes.
- IB and Cambridge programmes at international schools: roughly 3 to 8 lakh rupees a year, with IB Diploma years at the top of the range.
- ICSE or CBSE with international enrichment: roughly 1.5 to 4 lakh rupees a year.
- Boarding where available: add roughly 3 to 5 lakh rupees a year.
Extras include a one-off admission fee (often 50,000 to 2 lakh rupees at the international schools), a refundable caution deposit, annual charges for development or technology, uniforms, school transport, books, and external exam fees for IGCSE, A Level and IB billed at cost. One hard fact worth knowing: India's GST rate rationalisation that took effect on 22 September 2025 moved exercise books, notebooks, pencils and erasers to zero GST, while school tuition itself was already exempt. Stationery bills from the school shop should therefore be lower this year; if a school still charges 12 percent GST on notebooks, query it.
Practical advice for choosing well in Kolkata
Ask how many students actually sit the international exam. Several Kolkata schools advertise IB or Cambridge but run small cohorts in the senior years. Ask for the number of IB Diploma or A Level candidates in the last two years and the average points or grades.
Check the language balance in the classroom. Kolkata international schools are majority Indian, and Bengali and Hindi are spoken socially even where English is the medium. For a child with no Indian language that is rarely a problem academically, but it shapes friendships; visit during a break, not just a lesson.
Plan the commute for the monsoon, not for a dry Tuesday in November. Waterlogging on the Bypass and in New Town adds 30 to 60 minutes to school runs in July and August. Schools with reliable bus fleets and flexible late-arrival policies earn their keep in those months.

Frequently asked questions
Which international schools in Kolkata offer the IB Diploma?
Calcutta International School and The Heritage School are the best-established IB Diploma providers in the city, both in the Anandapur and EM Bypass area of south-east Kolkata. Pailan World School in Joka also offers IB programmes. Most other international schools in Kolkata run Cambridge IGCSE and A Level or an Indian board such as ICSE or CBSE with international enrichment.
How much do international schools in Kolkata cost in 2026?
Roughly 3 to 8 lakh rupees a year (about 3,500 to 9,500 US dollars) for IB and Cambridge programmes at the leading international schools, and roughly 1.5 to 4 lakh rupees at schools following ICSE or CBSE with international add-ons. Kolkata is meaningfully cheaper than Mumbai, Delhi or Bangalore for equivalent programmes. Add admission fees, transport, uniforms and exam fees.
Should an expat family in Kolkata choose an Indian board or an international curriculum?
Choose an international curriculum (IB or Cambridge) if you expect to move again or aim for universities outside India, because credits and predicted grades transfer cleanly. Choose ICSE or CBSE if you plan to stay several years and want the widest choice of schools, strong academic rigour and preparation for Indian university entrance. Many Kolkata schools let you switch to IB or A Level at age 16.
