About international schools in Colombo, Sri Lanka

Colombo’s international schools form a small, varied sector that mainly teaches through English and typically follows internationally recognised pathways - a minority offer the International Baccalaureate while several follow British-style IGCSE and A-level or Pearson/Edexcel routes. Parents will find English as the main medium of instruction, with Sinhala and Tamil commonly taught as local or second languages and a few schools offering additional language programmes such as French or Mandarin. Published tuition levels vary widely: some long-standing international schools publish annual fees in the mid-to-high five-figure US dollar range for older students, while other international or dual-pathway schools charge substantially less; many schools also levy registration, capital levies, transport, exam and activity charges so always request the full fee schedule. Schools in Colombo set term dates linked to the northern-hemisphere academic calendar and many run August/September and January intake windows, though some accept mid-year admissions and maintain rolling places for certain year groups, so apply several months ahead and ask about assessment and English-support arrangements for newcomers.

FAQs for Sri Lanka

What international curricula are available in Colombo and how do they differ?
You will find a mix: the International Baccalaureate is offered by at least one full IB school in Colombo, while several schools use British-style programmes (Cambridge IGCSE/AS/A-Level or Pearson/Edexcel) and some schools combine international and national pathways. IB programmes are integrated (with continuity from primary to diploma where available) and emphasise inquiry-based learning, whereas Cambridge and Edexcel pathways are more modular and exam-focused at IGCSE and A-Level stages; individual schools set the details of subject choice and assessment.
How much do international schools in Colombo cost and what extras should we expect?
Costs vary substantially between providers: an established international school in Colombo publishes annual tuition figures in the low-to-high five-figure US dollar range for older pupils, while other international or bilingual schools charge lower amounts in local currency; the exact level depends on age, curriculum and whether boarding or specialised services are provided. Beyond tuition, most schools publish separate charges for registration/enrolment, re-enrolment or capital levies, transport, uniforms, exams and after-school activities, so ask for a full, itemised fee schedule and the school’s payment and refund policies.
When should we apply and what does the admissions process usually involve?
Many Colombo international schools publish intake windows around August/September and January and will also accept applications for mid-year places when capacity allows, but popular year groups can fill early so it is wise to begin enquiries several months before you need a place. Admissions typically require an application form, previous school reports, an assessment or interview in English and sometimes maths, plus payment of an application or registration fee; schools will also outline any English-as-an-additional-language or learning-support arrangements for newly arriving students.
What languages are used and will my child need to learn Sinhala or Tamil?
Most international schools in Colombo use English as the language of instruction, while Sinhala and Tamil are commonly offered as compulsory or optional second-language subjects to reflect the national context. Several schools also provide other modern languages such as French or Mandarin, and larger international schools usually run English-language support (EAL) programmes for pupils whose first language is not English.
What practical things should parents compare when choosing a school in Colombo?
Look for clear information about the curriculum pathway and how it links to university or further-study progression, transparent and itemised fees, published term dates and intake rounds, and the school’s capacity to provide EAL and special-educational-needs support if required. Also check safeguarding policies, accreditation or external inspections, transport coverage and how the school communicates with parents, and ask for recent sample timetables and typical class sizes so you can compare what academic and pastoral provision will look like day-to-day.
