One World International School, known to most families as OWIS, is an IB World School in Singapore that has built its reputation on accessible fees and a diverse, multinational community. Established in 2008, it now runs three campuses across the island and teaches children from early years through to the IB Diploma. It appears in our editorial roundup of the cheapest international schools in Singapore precisely because it offers a full IB pathway at fees below the city's premium names.

Curriculum and academics
OWIS follows a recognisable IB through line. The early and primary years use the IB Primary Years Programme, an inquiry led framework that builds conceptual understanding across subjects rather than teaching them in isolation. In the middle years students prepare for Cambridge IGCSE, which gives a structured set of externally examined qualifications before the senior phase.
The IB Diploma Programme caps the pathway in the final two years, keeping university routes open across North America, the United Kingdom, Australia and Asia. The Nanyang and Punggol Digital campuses are authorised for the PYP and the Diploma, and the school draws students from more than 70 nationalities, which keeps classrooms genuinely international. As with any IB school, ask for the most recent Diploma cohort results and the average and highest points rather than rely on marketing summaries. Families weighing this against pricier names will find the curriculum comparable while the fee position is materially lower.

One World International School fees
| Stage | Annual tuition |
|---|---|
| Early Childhood 1 | SGD 21,749 |
| Grades 1 to 6 | SGD 21,749 |
| Grades 7 to 12 | SGD 25,005 |
Source: One World International School (owis.org). Annual tuition, Nanyang campus, in 3 instalments. Plus an annual building fee of about SGD 6,564. Fees are the most recent published figures and exclude one-off costs such as registration, deposits and capital levies. Always confirm current fees directly with the school.
OWIS sits toward the value to mid part of the Singapore fee market. In our Singapore international school fees guide the value band runs roughly SGD 14,000 to 24,000 a year and the mid band from SGD 24,000 to 35,000, and OWIS publishes tuition that places it below the upper mid and premium IB schools while still offering the full IB Diploma. Fees vary by campus and year group, so treat any single figure as indicative and confirm the current schedule with the school.
Beyond tuition, budget for a non refundable application fee, a registration or enrolment fee, a refundable deposit, and optional extras such as school bus, lunch, uniform and external examination entries in the senior years. Even at the value end of the market, Singapore schools tend to raise fees ahead of general inflation, so plan for an annual increase.
Admissions
The OWIS academic year runs from August to June, and the main intake is at the start of that year. Early years and primary entry points fill ahead of the year, so families relocating to Singapore should apply in advance, while mid year places are offered on a rolling basis where space allows. The opening of the Newton campus in August 2025 added capacity for younger children in the central area.
Admission usually involves an application with recent school reports, an age appropriate assessment, and a conversation with the admissions team. Entry into the IGCSE and IB Diploma years depends more on prior subjects and English readiness, so confirm subject availability at your chosen campus before committing.
Location and who goes there
OWIS spreads across three sites. The Nanyang campus sits in the west at Jurong West, the Digital Campus is in the north east at Punggol, and the Newton campus opened in central Singapore in 2025 for younger children. That spread lets families choose the campus nearest their home, with western families often near Jurong and the Lakeside corridor and north eastern families around Punggol and Sengkang. The community is genuinely multinational, drawn to the school by the combination of an IB pathway and accessible fees.

We would rather show nothing than show an invented score.
If your family has attended the school we would value your account of admissions, teaching, pastoral care and value for money. Share it through our school reviews hub and we will add verified contributions to this page.
