Kolkata has a long tradition of English-medium education going back to the nineteenth century, and today that heritage sits alongside a newer generation of international campuses on the eastern side of the city. Families relocating for IT, consulting, banking and manufacturing roles, as well as returning Indian families, now have a real choice of boards and price levels. This guide to the best international schools in Kolkata explains what each shortlisted school offers, what it costs in 2026 and how to decide.

Where families live in Kolkata

Expat and relocating families tend to live in Salt Lake (Bidhannagar), New Town and Rajarhat, where the IT parks are, or in the established southern neighbourhoods of Ballygunge, Alipore and Gariahat. Several of the newer international schools sit on the Eastern Metropolitan Bypass or further south along the Diamond Harbour Road, so the commute can be long. Kolkata's metro network has expanded in recent years, including the first underwater metro section under the Hooghly, but school buses remain the practical choice for most children.

Boards and curricula you will find

International Baccalaureate, mainly the Diploma Programme in Grades 11 and 12, offered alongside an Indian board at several schools.
Cambridge IGCSE and A Level, popular with families who may move abroad.
CBSE, the national board, with board exams in Grades 10 and 12.
ICSE and ISC, the CISCE board, traditionally strong in Kolkata and known for its emphasis on English.

One verifiable change for 2026: CBSE has introduced two board examination windows for Class 10 from 2026, a main exam in February and an optional second attempt in May for students who want to improve their scores. Ask CBSE schools how they are preparing students for the new format.

The international schools families shortlist

Calcutta International School

Calcutta International School is one of the city's best-known English-medium schools with an international outlook. It offers Cambridge qualifications alongside the Indian boards and has a long record of sending students to universities in India and abroad. Expect a competitive admissions process.

The Heritage School

The Heritage School, on the eastern side of the city, is a large campus offering several pathways, including CBSE and international programmes in the senior years. It is often chosen by families who want extensive facilities and a wide choice of subjects under one roof.

GEMS Akademia International School

GEMS Akademia International School belongs to GEMS Education, one of the largest private school groups in the world. It combines an Indian board with international teaching methods, which suits families who want global links and the option of moving to other GEMS schools in the Gulf or elsewhere.

Modern High School for Girls

Modern High School for Girls is a long-established girls' school in south Kolkata with a strong academic reputation and international qualifications in the senior years. It is a natural choice for families looking for single-sex education with an international outlook.

Pailan World School

Pailan World School is part of a Kolkata education group and offers a modern campus with an international curriculum option. Its fees sit below the most expensive schools in the city, which makes it attractive for families on a moderate education allowance.

Other schools worth a look

The Cambridge School, Vidyanjali International School, Adamas International School, Bridge International School and Garden High School complete the picture, from established ICSE schools to newer campuses with international programmes. Include one or two in your visits if location or fees are a priority.

How much do international schools in Kolkata cost?

Fees are quoted in Indian rupees and are usually split into an admission fee, an annual charge and monthly or quarterly tuition. Indicative annual totals for 2026-27:

IB Diploma and Cambridge A Level programmes: roughly INR 5 lakh to 8 lakh a year.
International schools with Cambridge or CBSE in the primary and middle years: roughly INR 2.5 lakh to 5 lakh.
Established CBSE and ICSE schools: roughly INR 1.5 lakh to 3 lakh.

Extras to budget for:

One-off admission fee, roughly INR 50,000 to 2 lakh, often non-refundable.
Refundable caution deposit at some schools.
School bus, roughly INR 30,000 to 70,000 a year depending on distance.
Uniforms, books, meals, trips and exam fees for Cambridge or IB.

How to choose between them

Start with the board. If you expect to move abroad in the next few years, Cambridge or IB keeps doors open. If your children will stay in the Indian system, CBSE or ICSE may be the better long-term choice, and many schools let you switch to IB for the last two years.

Apply in the right window. Most Kolkata schools open admissions for the April academic year between August and December of the previous year, with earlier deadlines for nursery. International programmes sometimes follow an August start, so check the calendar for each pathway.

Weigh the commute seriously. A school on the Bypass may be ideal for a family in Salt Lake but a long ride from Alipore, especially in the monsoon. Try the route at school time before committing.

What to ask on a school visit

Class sizes and teacher training. Ask how many children are in each class, how many teachers hold international certifications such as IB or Cambridge training, and how the school supports new teachers. These details often explain the difference between two schools with similar fees.

Support for children joining from abroad. If your child has studied in another system, ask how the school assesses their level, whether there is help with Hindi or Bengali as a second language, and how flexible the school is with language requirements in the upper grades.
