Frequently asked questions
Clear answers for parents
Does DeepThink have a class specifically for ISS International School's IB curriculum?
Yes. ISS International School students follow the IB Mathematics curriculum, and we run a dedicated IB Math class to match.
How does the IB Math curriculum differ from the local secondary syllabus?
IB Math covers different content at a different pace from the MOE secondary syllabus. Students who attend a general secondary tuition class risk spending time on O-Level or SEC exam content that won't appear in their assessments. Our dedicated IB class avoids that.
When should an IB student start tuition?
We recommend starting early — the IB curriculum diverges from the local secondary syllabus quickly, and gaps compound. Students who join mid-programme can also be accommodated.
What makes DeepThink different for IB students?
A dedicated IB class that stays on the IB curriculum throughout your child's secondary years.
School Overview
ISS International School is a co-educational international school in Singapore and one of the country's oldest, founded in 1981. It is an International Baccalaureate (IB) World School offering a full all-through education from Kindergarten to Grade 12, and is among the longer-established IB schools in Singapore. The school sits on a heritage hilltop campus at 21 Preston Road, a green site with a British colonial history that traces back to the late 1930s, when the grounds were used as a military outpost and later as the home of Alexandra Grammar School, which served the children of British forces stationed in Singapore.
ISS once operated a second campus in the Orchard area for its younger students, but the school unified its sections at the Preston Road campus in 2020, bringing the early years, middle, and high school together on a single site. It is a comparatively small school by Singapore international-school standards, and it emphasises small class sizes and a close, personal learning environment. The student body is international and drawn from families living in Singapore, in keeping with the school's standing as a private international school rather than a local Ministry of Education institution.
Curriculum and the IB Pathway
ISS International School follows the IB Continuum, offering all three International Baccalaureate programmes in sequence. Children begin in the IB Primary Years Programme (PYP) in the early years and primary grades, move into the IB Middle Years Programme (MYP) through the middle and lower-secondary years, and complete their schooling with the IB Diploma Programme (IBDP) in Grades 11 and 12. For students who prefer a different final route, the school also offers the ISS High School Diploma (HSD), an American-style two-year alternative to the IB Diploma. Unlike some international schools in Singapore, ISS does not offer the Cambridge IGCSE; its pathway runs through the MYP into the Diploma or the HSD.
This is a genuinely international pathway and differs from the Singapore MOE syllabus in both content and assessment: there is no PSLE, no O-Level, and no Singapore-Cambridge SEC examination, and the IB approach emphasises inquiry, concept-based learning, and the Diploma core of Theory of Knowledge, the Extended Essay, and Creativity, Activity, Service. At Diploma level, Mathematics 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 university 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, some families look for support matched specifically to the IB. 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 ISS families find useful for consolidating understanding ahead of the Diploma years.
Admissions
Admission to ISS International School is by application directly 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, and places are offered on the basis of the school's own assessment of each child's readiness and fit with the IB programmes, alongside the availability of places in the relevant year group.
As an international school, ISS admits students of many nationalities, and the student body is drawn from internationally mobile and expatriate families living in Singapore. Under Singapore government policy, local Singapore citizens generally require approval to enrol in an international school. Prospective families are encouraged to begin the application process ahead of their intended start date, as places in a small school can be limited at popular entry points. The school's admissions office publishes the current entry requirements, assessment steps, and fee information, and is the authoritative source for families who are applying.
Facilities and Co-Curricular Activities
The Preston Road campus is a heritage hilltop site set within a green, leafy setting, combining conserved colonial-era buildings with teaching and learning spaces for the school's Kindergarten-to-Grade-12 community. The campus provides facilities for academic study, science, sport, and the arts, and its outdoor, nature-rich surroundings are part of the character of the school. Bringing all sections together on one site since 2020 has allowed younger and older students to share a single campus community.
Alongside the academic programme, ISS offers a co-curricular programme spanning sport, the arts, and special-interest activities that complements classroom learning and supports the well-rounded development the IB encourages. As a small school, ISS aims to give students opportunities to take part across a range of activities rather than specialise narrowly, and co-curricular involvement is woven into the wider life of the school community.
School Community and Culture
ISS International School is a small, international community with a long history in Singapore, and its culture reflects both its heritage campus and its international student body drawn from families living in the city. The school's relatively small size supports a close, personal environment in which teachers know their students well, and pastoral care and individual attention are central to how the school describes its approach. As an IB World School, ISS places emphasis on international-mindedness, inquiry, and the development of the whole child across all three IB programmes.
For many families, joining ISS also means navigating a move to Singapore and a change of curriculum at the same time, and students entering the middle and senior years sometimes need to settle quickly into the demands of the MYP and the IB Diploma. 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, are one option that some families in the ISS community use to help their children build confidence during this transition and through the Diploma years.

Where is ISS International School located?

How is IB Mathematics at ISS International School different from the local Singapore syllabus?
IB Mathematics is part of the International Baccalaureate Diploma and differs from the MOE secondary and A-Level syllabuses in both content and structure. Students take either Analysis and Approaches or Applications and Interpretation rather than E-Math, A-Math, or H2 Mathematics, so support matched to the IB is more relevant than general O-Level or A-Level preparation.
Can my child get extra help with IB Mathematics while at ISS International School?
Yes. DeepThink runs small-group classes aligned to the IB Mathematics curriculum, covering both the Analysis and Approaches and Applications and Interpretation routes at Standard and Higher Level. Lessons follow the IB syllabus rather than the local secondary syllabus, which suits students on the ISS pathway through the Middle Years Programme and the Diploma.
What co-curricular activities does ISS International School offer?
ISS offers a co-curricular programme spanning sport, the arts, and special-interest activities that complements the academic curriculum and supports the well-rounded development the IB encourages.
