OASIS International School

What OASIS International School does

OASIS International School (OIS) is a private K-12 institution operating from a single campus at 9 M D Gunasena Mawatha, Colombo 12, Sri Lanka. Founded in 2000 as a subsidiary of M.D. Gunasena — a century-old Sri Lankan conglomerate historically associated with publishing and education — the school delivers education from Pre-School (ages 2.5-5.5) through Grade 12. Its core product is a dual-curriculum offering that combines the Pearson Edexcel international pathway (IGCSE and International Advanced Level) with the Sri Lankan National Curriculum taught in English medium, allowing students to transition between tracks. The school highlights a #2 Pearson Edexcel World Prizes ranking and consecutive World Prize achievements in Accounts (2014-2017), and its IT facilities are recognized by the British Council as meeting international standards.

The institution operates on a tuition-based recurring revenue model, supplemented by ancillary income from facility rentals (225-seat Lilian Auditorium, computer and science labs, swimming pool, sports grounds) and examination registration services for external Pearson Edexcel candidates. Adjacent offerings include Day Care for the school community, an in-house Teacher Training Diploma program in Early Childhood Education, and an extensive extracurricular catalog (swimming, football, choir, debating, Model UN-adjacent clubs, and others). Distribution is direct-to-consumer: prospective parents complete an application, verify documents, sit for an entrance assessment, and pay fees through an online portal (myfees.lk) or in person at the registrar's office. The student body is drawn from diverse communities in Colombo, with the gated admissions process (entrance assessment, parental commitment to school ethos) acting as a quality filter alongside academic selectivity.

The school is privately held and family-operated, with Managing Director M.D. Rajiv Gunasena and Education Consultant M.D. Tarusha Gunasena maintaining active stewardship alongside Principal Chathurika Perera. Headcount stands at 24 employees, consistent with a single-campus boutique institution rather than a multi-site operator. Marketing is conducted through the school's website, Facebook, YouTube, LinkedIn, Instagram, and TikTok channels, supplemented by parent testimonials and open days. No external funding, M&A activity, or geographic expansion beyond Colombo is evidenced in the source material.

Direct peers

• Elizabeth Moir School: Well-known Colombo international school offering Cambridge IGCSE and A-Levels. Direct competitor in the British-curriculum K-12 segment serving the same aspirational middle-class segment as OIS.
• British School in Colombo: Colombo-based international school offering British curriculum pathways (IGCSE/A-Levels) to local and expat students. Operates in the same price tier and curriculum space as OIS, making it a direct peer for parental choice.
• Wycherley International School: Long-established private international school in Colombo offering Pearson Edexcel and Cambridge curricula from primary through secondary. Closest direct competitor to OIS in the British-curriculum K-12 segment in Colombo.
• Stafford International School: Colombo-based private international school delivering a British-style curriculum (Pearson Edexcel) from early years through secondary. Directly competes with OIS for fee-paying families seeking international qualifications in Colombo.
• Colombo International School: International school in Colombo offering IGCSE and A-Level programmes to both local and international students. Competes with OIS on British-curriculum credentials and university placement narrative.
• Asian International School: Colombo-based private school providing both national and international curriculum streams, including Edexcel pathways. Competes head-to-head with OIS's dual-curriculum positioning in the same metro market.

Broad incumbents

• Royal College, Colombo: Historic government-aided private school in Colombo with a long-established reputation and a national curriculum. Competes with OIS for academically inclined Colombo families, though it does not offer the same Edexcel international pathway.
• S. Thomas' College, Mount Lavinia: One of Sri Lanka's most prestigious private boys' schools offering both national and Cambridge international curricula. While a national landmark institution rather than a focused competitor, it competes for the same high-achieving Colombo families.

Others

• M.D. Gunasena (Parent Group): Parent company of OASIS International School, a century-old Sri Lankan educational publishing conglomerate. Not a competitor but a closely linked ecosystem participant that supplies brand, content, and corporate resources.

Regional players

• Musaeus College: Leading private girls' school in Colombo offering national and Cambridge curricula. Regional Colombo peer competing for academically focused families but in a single-sex setting that differentiates it from OIS.
