One World International School Singapore

What the school is

School history, ownership and programme status

OWIS opened at Upper Changi Road in 2008 and was acquired by Global Schools Foundation in 2015. The group, also associated with GIIS, describes itself as a non-profit founded in 2002. OWIS won a government tender for a moderately priced international school in 2017. Nanyang opened in January 2018 with more than 250 pupils, growing to over 1,200 in its second year, according to the school’s history.

The tender is part of Nanyang’s history, rather than a measure of the quality of its current teaching. The school records a four-year EduTrust award in 2020 and registration number 200800495N for 24 February 2023 to 23 February 2027. A registration period is not the same as a current EduTrust certification period. Programme listings describe PYP, IGCSE and Diploma provision at Nanyang and Digital, and Cambridge A-level registration at Digital. Those listings need to be read alongside the grades and courses actually open for entry.

Secondary profiles describe a policy limiting any single nationality to 30% of the pupil population. The school does not say whether that limit applies across the school or by campus. It should not be presented as a guarantee of each classroom’s composition. Admissions can explain whether and how the policy affects a particular application.

Three campuses

Nanyang, Digital and Newton: different campus provision

Nanyang is at 21 Jurong West Street 81 and offers Early Childhood through Grade 12, with a Chinese-English bilingual option reported in Grades 3–5. The Digital Campus is at 27 Punggol Field Walk within Global Campus Village. Opening material describes 22 skill studios on site and 41 shared within the wider village; it does not place all 60-plus studios exclusively at OWIS.

Newton is at 99 Bukit Timah Road and opened in August 2025 for Early Childhood through Grade 5. The school notice describes it as a candidate for the IB PYP. Candidacy is distinct from authorisation and does not guarantee it. Families should establish the current status and curriculum provision for the intended entry date.

The official Nanyang tuition range for 2026–27 is S$24,158–27,774. Secondary reporting lists Newton at approximately S$26,491 and the Digital Campus at S$31,449–40,459. The Digital range includes senior-year pricing that does not, by itself, establish which grades are currently operating. Older material mentions a Suntec site opened in 2021, but the fee tabs list Nanyang, Digital and Newton. We found no Suntec closure notice, so the omission should not be treated as proof of a particular closure or consolidation.

Academics in practice

The IB and Cambridge sequence and reported results

The documented Nanyang sequence uses PYP through Grade 5, a modified Cambridge curriculum in the middle years, Cambridge IGCSEs in Grades 9–10 and the IB Diploma in Grades 11–12. Academic English preparation is available for pupils developing the language needed for secondary study. This is a combination of IB and Cambridge programmes, rather than the full PYP–MYP–Diploma continuum.

For Nanyang’s 2025 IB cohort, WhichSchoolAdvisor reports a 100% pass rate, an average of 32 and a top score of 40. School reporting gives an average of 33. The discrepancy remains unresolved, so the figures should not be blended into a single verified result. A top score of 45 is reported for 2024. Named alumni destinations include Sydney, Melbourne, Warwick, Edinburgh, NUS, Waseda and UBC, but a dated cohort destination report is needed for comparison.

Provision includes English-language programmes, additional learning support and counselling. A secondary profile reports teacher-to-pupil ratios from 1:9 in Early Childhood to 1:24 from Grade 2; these are not individual class sizes or a measure of specialist support capacity. The school needs to assess each child’s requirements and confirm what is available at the chosen campus.

Fees and the real cost

Tuition inclusions and separate charges

Official Nanyang tuition for 2026–27, including 9% GST, is S$24,158 for Early Childhood 1–3 and Grades 1–6, S$27,774 for Grades 7–12 and S$25,936 for Grade 5 in the bilingual programme. A one-time non-refundable application fee of S$1,420 is separate. Tuition is payable in three instalments and includes two uniform sets, textbooks and scheduled academic field trips.

The miscellaneous schedule lists annual charges of S$7,085 for Additional English Support, S$8,175 for Enhanced English Support, and S$6,540 each for Additional Learning Support or Additional Counselling Needs. AEPP has separate semester fees of S$12,079 for Grade 6 and S$13,887 for Grades 7–8; do not assume these are automatically added to full mainstream tuition. The schedule also lists S$1,635 per activity per term for ECAs and S$3,270 per instrument per year for music. School-managed device prices include an iPad with AppleCare at S$619, a S$57 case and a MacBook Air with AppleCare at S$1,581.

The listed 2026–27 annual two-way bus charges are S$4,296 for up to 3km, S$4,777 for 3–10km and S$5,257 for more than 10km. Bus use is optional. The payment terms require GIRO after the first instalment and list a S$109 non-GIRO charge, S$109 monthly late-payment charge and S$218 for a returned GIRO payment or cheque. The seven-working-day cooling-off period after signing is governed by the refund terms in Schedule D of the student contract.

For a Grade 7 pupil at Nanyang, S$27,774 tuition plus S$8,175 Enhanced English Support and S$5,257 for the longest-distance bus band totals S$41,206 per year. Adding the S$1,420 application fee gives a first-year subtotal of S$42,626. This excludes any required device, activities or other assessed services. It is an example using the listed charges, not a complete quotation or a comparison of educational value.

Admissions and fit

Entry requirements, scholarships and discounts

OWIS describes its admissions as non-selective, with age-appropriate assessments and programme requirements. Secondary reporting describes case-by-case primary interviews, assessments in Grades 6–8 and additional requirements for IGCSE and Diploma entry. Availability, language or learning support, and the application of the reported nationality policy need to be checked for the specific campus and grade.

The school advertises scholarships and a Corporate Connect programme for partner-company discounts. Published sources do not give complete eligibility, award values or renewal conditions. These should be confirmed before reducing a family budget or assuming an award is available for the intended campus and entry year.
