School Overview
Overseas Family School (OFS) is an independent international school in Singapore that has educated children from internationally mobile families since 1991. It was founded by Mdm Wong Lok Hiong and Mr David Alan Perry and opened at Paterson Road in the city centre, where it grew over more than two decades into one of Singapore's larger international schools. In 2017 the school relocated to a purpose-built campus at Pasir Ris Heights, in the east of the island, designed to bring its early years, primary, and secondary sections together on a single modern site.
OFS is an International Baccalaureate World School and offers a continuous English-medium education from Pre-K1, for children as young as two, through to Grade 12. The school serves a highly international community drawn from expatriate families living in Singapore, with students representing more than seventy nationalities. Rather than preparing students for Singapore's national examinations, OFS follows international curricula throughout, leading students toward the IB Diploma and the Cambridge IGCSE in the senior years. Its stated philosophy — that a happy child is a successful student — reflects an emphasis on well-being and belonging alongside academic progress.
Curriculum and the IB Pathway
OFS provides a structured international pathway that begins with the International Early Years Curriculum (IEYC) in Pre-K1 to Kindergarten, continues through the International Primary Curriculum (IPC) across Grades 1 to 5, and moves into the International Baccalaureate for Grades 6 to 12. In the middle years students follow the IB Middle Years Programme, and in the senior years they work toward the IB Diploma Programme; the Cambridge IGCSE is also available as part of the secondary offering. This is a genuinely international route and differs in content, pace, and assessment from the Singapore MOE syllabus — there is no PSLE, no O-Level, and no Singapore-Cambridge SEC examination along the way.
Mathematics at the Diploma level is taken as one of two routes — Mathematics: Analysis and Approaches or Mathematics: Applications and Interpretation — each offered at Standard or Higher Level, and the choice shapes a student's options in fields such as engineering, economics, and the sciences. Because the IB Mathematics syllabus moves at a different pace and covers different material from the local curriculum, families sometimes look for support matched specifically to the IB rather than to O-Level or A-Level preparation. DeepThink, a specialist mathematics tuition centre, runs small-group classes aligned to the IB Mathematics curriculum, including both the Analysis and Approaches and Applications and Interpretation routes, which some OFS families find useful for consolidating understanding ahead of the Diploma years.
Admissions
Admission to OFS is by direct application to the school rather than through Singapore's PSLE posting exercise or the Direct School Admission scheme, which apply only to local MOE schools. Families apply for a specific entry point along the school's continuous pathway, and places are offered on the basis of the school's own assessment of each child's readiness and the availability of places in the relevant year group.
As an international school, OFS draws its students overwhelmingly from expatriate and internationally mobile families; under Singapore government policy, local Singapore citizens generally require approval to enrol in an international school. The school admits children from as young as two years old in its early years section through to Grade 12, and because families often arrive in Singapore partway through the academic year, entry can occur at various points rather than at a single fixed intake. Prospective families are encouraged to begin the application process ahead of their intended start date, as demand at popular year groups can be high. Specific entry requirements, assessment steps, and fee information are published by the school's admissions office and are the authoritative source for current applicants.
Facilities and Co-Curricular Activities
The Pasir Ris campus is a large, purpose-built site that houses the early years, primary, and secondary sections together with extensive shared facilities. These include a large auditorium, a fifty-metre indoor swimming pool, multiple basketball courts, well-resourced science laboratories, several libraries, and dedicated music studios, giving students room for sport, the performing arts, and inquiry-based learning across a single connected campus.
Beyond the academic timetable, OFS supports a broad co-curricular programme spanning sport, music, the visual and performing arts, and a range of clubs and special-interest activities. The breadth of facilities allows the school to offer activities to students across all ages, from the youngest children in the early years through to senior students in the Diploma years. As with most international schools, the specific clubs, teams, and competitions on offer vary from year to year, and the school's own activities listings are the best guide to what is currently available.
School Community and Culture
OFS describes itself as a happy, safe, and inclusive school in which each child's cultural identity is honoured and valued, and this outlook shapes the daily life of a community that brings together students from more than seventy nationalities. The guiding idea that a happy child is a successful student sits at the centre of the school's approach, with pastoral care and a sense of belonging treated as foundations for learning rather than afterthoughts. For families relocating to Singapore, this internationally minded environment is often part of the appeal, offering continuity and welcome during a period of transition.
Joining OFS frequently means navigating a move to a new country and, for older students, a change of curriculum at the same time. Mathematics is a subject where a smooth transition matters, because the IB approach can differ noticeably from a student's previous system. DeepThink's small-group IB Mathematics classes, which follow the IB curriculum rather than the local syllabus and cover both the Analysis and Approaches and Applications and Interpretation routes, are one option that some families in the OFS community use to help their children build confidence as they settle in and progress through the Diploma years.

Frequently asked questions
Clear answers for parents
Which Math class suits a Overseas Family School student?
The relevant pathways are IB pathway. We use the student's current Mathematics course, year and schoolwork to choose a class. Students learn with others studying the same course at a suitable pace.
Are secondary IB-pathway lessons the same as IB Diploma lessons?
The secondary years build towards the Diploma. Schools may use their own pre-IB course, MYP or IGCSE, with different topic sequences and assessments. These secondary course links cover the years before the Diploma; share the actual school course and year so we can confirm the right fit.
When should a secondary student start tuition?
Start when schoolwork reveals gaps in understanding or confidence. Earlier support can strengthen algebra and problem-solving foundations; students joining later can focus on their current topics and assessments.
What makes DeepThink different for Overseas Family School students?
Small classes, teaching matched to the student's actual Mathematics course, and practice that develops clear working as well as correct answers. Parents are kept informed about progress and areas needing more practice.
How many students are in each class?
Four, at most. Students are grouped by learning pace, not just by year level, so each lesson moves at the speed of the students actually in it. When no session matches a child’s pace, we open a new one. In a class that size, every child answers questions, gets their working checked, and gets help the moment they need it.
Can families start with a trial class first?
Yes. A trial class helps you see whether our teaching pace and approach suit your child’s learning needs. Trials in existing classes are free. A dedicated trial session at a different timeslot is offered at a subsidised rate of $30. We’ll help you explore the available options.
