Integrated International School (IIS), at Capital Square Two, 21 Church Street #01-01, Singapore 049480, is an inclusive private international school offering British-based lower-secondary education and Pearson Edexcel IGCSE at upper secondary. Parents considering IIS after PSLE 2026 should know that it is not in the ordinary MOE six-school Secondary 1 Posting Exercise and has no PG1, PG2 or PG3 cut-off. IIS offers Lower Secondary Grades 7–9 from about age 11 and Upper Secondary Grades 10–11 from about age 14, with personalised teaching, a published 1:6 teacher-student ratio and support arrangements that must be matched to the individual child.
The school’s official 2027 tuition table lists S$37,000 for mainstream lower- or upper-secondary study and S$45,000 for its Mainstream with Support option, both including GST. Its current admissions page also lists a non-refundable S$2,800 application fee, with books, transport, ECA activities, examinations and certain external therapy services charged separately. IIS processes applications on a rolling basis, reviews school records and support needs, and conducts a family meeting before offering a place. A Singapore citizen may need MOE permission for foreign-system schooling; neither a strong PSLE score nor payment of the application fee guarantees admission.

What parents need to understand about Integrated International School
IIS offers personalised British-based international learning in the city centre, with the school’s own admission and support criteria. It is not a government secondary school allocated via PSLE Posting Groups. A family should understand the student’s age-appropriate grade, the curriculum, any individual learning plan, costs and the ordinary commute rather than choose purely by reputation.
Why there is no historical PSLE cut-off at IIS
Singapore’s Secondary 1 Posting Exercise creates historical cut-off ranges for participating mainstream schools. An independent foreign-system-school provider cannot be assigned a published Posting Group 1, 2 or 3 endpoint from this system. A pupil with a strong PSLE total still needs to meet IIS’s admission and educational suitability process, while a learner who finds one subject difficult should not be judged solely by that total.
The family’s decision must start with correct eligibility. Ask which programme the pupil would enter, what records and assessments are required, and what support the receiving teachers can genuinely provide. The school should make the distinction between academic readiness and individual learning-support needs clear.
The first practical question is which curriculum the child will enter
IIS describes a modified British curriculum for its lower-secondary programme and Pearson Edexcel International GCSE at upper secondary. A child leaving Singapore Primary 6 would not automatically enter an ordinary MOE G3 class. The receiving school needs to check age, current subject knowledge and appropriate year placement. Grade 7 begins from approximately age eleven under the school’s stated pathway, with Grades 8 and 9 continuing the lower-secondary programme.
Parents should ask for a real Grade 7 timetable and samples of the tasks students complete in English, Maths and Science. A pupil may know Singapore primary Mathematics yet encounter British-based topics or written explanations in a different order. The school should identify the exact gaps and teach them, rather than assume a high PSLE total means the child can manage all future study without additional guidance.
The curriculum should prepare learners for the later qualifications actually offered. If the family expects an O-Level-equivalent outcome, ask about Edexcel International GCSE subject registrations, the grades needed for progression and the support given before final examination entry. School-level coursework and external examinations are not interchangeable.
Lower-secondary teaching combines core subjects with practical and social learning
The IIS lower-secondary description includes English, Mathematics, Science, Topic of Inquiry, Creative Arts, Home Economics, Social Skills Training, and Personal Development, Health and Physical Education. This mix indicates an ambition to develop academic and social competencies together. Families can use the subject list to ask what a typical week looks like rather than infer that every student receives identical enrichment.
Topic of Inquiry can be useful when students learn to ask a specific question, find reliable information and explain a result. Suppose pupils investigate whether a school’s water use could be reduced. A meaningful project would involve measurement, explaining assumptions, checking how people use water and proposing a change that could actually be tested. An attractive poster alone is not sufficient evidence.
Parents should ask how these projects are taught to students with different learning profiles. A learner confident in Science but hesitant to speak could contribute careful observations while learning to present them more clearly. Another pupil may need more explicit help reading a lengthy instruction. The point of individualisation is growth in genuine understanding.
Upper-secondary IGCSE: what the school says it offers
IIS lists Pearson Edexcel International GCSE for Grades 10–11, with subjects including English, Mathematics, History, Accounting, Business and Information and Communication Technology. Its page describes the programme as a two-year pathway for students generally aged fourteen to sixteen. The school has flexibility to plan individual study programmes, but families should confirm the current subject timetable and external-examination arrangements.
An International GCSE is not automatically the same paper as Singapore’s national Secondary Education Certificate. Both involve subject study and assessments, yet the examining bodies, course content and later progression details differ. Parents should ask precisely which external subjects the child could take and how those results would be used for applications to other education providers.
Additional subject choices can be attractive, but time and prerequisites matter. A young pupil may develop an interest in Computer Science after entering, or discover a need to strengthen algebra before choosing advanced Maths. The school should help the family revisit options based on demonstrated progress rather than require a permanent career decision at twelve.
A-Level progression is a possibility, not an automatic place
IIS’s fee structure and programme overview list Cambridge International AS and A-Level courses for older students, after the relevant lower- and upper-secondary stages. This can offer a pathway beyond International GCSE, but it is subject to the school’s current subject registration, admission requirements and the student’s readiness.
Parents should ask whether the same campus teaches the subjects the child might later want, which external examinations are available and how tuition changes at the post-secondary stage. A-Level subject selection may matter for entry to later courses, but there is no need to lock in a particular university plan at the beginning of secondary school.
The more durable preparation is good reading, numerical confidence, careful scientific reasoning and a willingness to seek feedback. These habits support later study no matter which external qualification the child eventually attempts.
What the school’s published 1:6 ratio means—and what it does not
IIS’s 2026 homepage states a teacher-student ratio of 1:6 in both primary and secondary programmes. That is a helpful figure for families seeking individual attention, but it does not tell you the precise composition of a particular Grade 7 class or every specialist lesson. Ask whether the figure is a whole-school staffing ratio, a typical class size or the maximum in certain teaching settings.
Small groups can make it easier to detect a misunderstanding early and provide targeted practice. A pupil struggling with fractions may be given worked examples and short checks before progressing; another may need help organizing an essay. But size alone does not guarantee the quality of feedback or the fit of a student’s curriculum.
Ask the teachers how progress is measured: can the child explain an answer, work under time limits when appropriate and apply understanding to an unfamiliar task? Parents need evidence of actual improvement rather than only an assurance that every learner receives personal attention.
In-house support requires an individual discussion
The IIS website describes a Support Department providing access to individualised education plans, behavioural and counselling support, speech and language therapy, occupational therapy and social-skills training. These services can be important to a family considering education outside the mainstream system. However, parents should not infer from the list that every specialist service is automatically included in the annual course fee.
The admissions process asks families to submit relevant educational, psychological and specialist reports where applicable. This helps the school determine whether it can meet the child’s needs and what arrangements are appropriate. An honest family discussion should specify the supports that have helped, the barriers that remain and the goals that matter to the child.
Ask which services are part of the Mainstream with Support package, which require external practitioners or separate charges, and how progress is reviewed. A published list of services is not a guarantee that the school can accommodate every individual need or that a student must receive a particular intervention.
Learning-support fees have a different meaning from tuition
The official 2027 school-fee page lists S$37,000 for the mainstream programme and S$45,000 for Mainstream with Support, GST included. This is a meaningful distinction and should be placed clearly in a family budget. It may reflect integrated school support but does not necessarily cover every individual therapy, assessment or resource.
The same page explains that school uniforms, booklets, examination fees, transport, extracurricular activities and external therapy services may be billed separately. Parents should ask for a personalised written invoice showing the child’s specific support plan and whether charges are monthly, semesterly or annual.
Fee protection and the private education contract should also be discussed. When a family is uncertain about whether the programme meets the child’s needs, the refund rules and the assessment period are especially important. Do not pay non-refundable fees on the assumption that a later trial will be risk-free.
The 2027 fee rise should be acknowledged rather than hidden
IIS published 2026 course fees of S$34,651.10 for mainstream and S$41,583.50 for mainstream with support, and the same page lists 2027 increases to S$37,000 and S$45,000. Both years’ figures are described as GST-inclusive. This difference matters when parents find a search result quoting a lower price and assume it is the current offer.
The application page separately lists a non-refundable S$2,800 application fee. Parents should ask whether the family interview, placement assessment or requested specialist review involves any additional cost. Further charges may be linked to the programme or support a specific student needs.
A four- or five-year decision should be considered against the family’s recurring budget, not a single term’s tuition. Leaving a school partway through a course may involve contractual consequences. Read the Student-School Enrolment Agreement and fee-protection arrangements carefully.
Admission is a family-and-school suitability decision
IIS currently accepts applications on a rolling basis, considering submissions in chronological order. Its admissions page asks for identification, school transcripts for the previous two years and relevant learning reports. The process includes an introductory campus visit, document review, a family interview with the principal and a formal offer if the school judges the match suitable.
The family interview is not simply a test of a parent’s enthusiasm. It gives the school information about the pupil’s academic history, strengths, learning support and transition needs. Parents should ask what the child will actually experience and whether the school can provide the necessary staff and curriculum.
Singapore-citizen applicants should verify the applicable MOE exemption or permission procedure. The school states that its admissions team can assist with the relevant arrangements. A parent should not assume that private enrolment is automatic or disregard any required local S1 posting while approval is unresolved.
Church Street means a city-centre commute, not a neighbourhood-school journey
The school is at Capital Square Two, 21 Church Street, #01-01, Singapore 049480. Its published directions reference Raffles Place and Telok Ayer MRT. The setting is different from a sprawling campus with its own sports field, so families should ask where outdoor PE, sports and extracurricular activities take place.
A student from Punggol, Sengkang, Jurong or Tampines may need a long rail journey with morning crowds and an additional walk. Test the route at the actual reporting time, including a late dismissal when extracurricular activities occur. A direct rail line does not always equal an easy journey for a twelve-year-old carrying a full bag.
Check the school calendar, possible transport arrangements and whether support services extend beyond ordinary lessons. A school can be intellectually appropriate yet practically exhausting when every afternoon disappears into travel. The family should weigh all these factors before making the choice.
Ten questions to ask before applying
- What exact grade would this Primary 6 pupil enter and what determines placement?
- How does the published 1:6 ratio relate to actual class and subject group sizes?
- Which lower-secondary subjects and upper-secondary IGCSE courses are currently registered?
- What does Mainstream with Support include and what costs extra?
- Can the school meet the child’s documented educational or communication needs?
- How do staff diagnose Mathematics, English and Science gaps and report progress?
- What are the enrolment, application, assessment and withdrawal requirements?
- What MOE or immigration permissions must be secured before the pupil starts?
- What CCAs, sports facilities, transport and late dismissal arrangements apply?
- What is the complete first-year cost and a realistic plan for later years?
PSLE results day and the seven-day school-choice period
As of 5 November 2026, the 2026 PSLE results had not yet been released. The Singapore Examinations and Assessment Board lists 24–25 November 2026 as the tentative result-release window; the actual day must be confirmed by official announcement. Parents should not assume that a private school’s rolling enrolment process follows the same submission window.
An applicant with an unresolved IIS application may still need to complete ordinary MOE S1 choices. If the child has no approved and confirmed alternative place, follow the current primary-school and MOE instructions rather than relying on an informal private-school enquiry. Keep all receipts and offers separate from actual confirmed enrolment.
Preparing the child for a new learning environment
Ask the child what they hope to learn, which subject still feels difficult and how they would prefer to ask for help. The first weeks in a new curriculum can be confusing. A clear homework system, steady sleep and one manageable club can help. Parents should work with teachers to identify exact difficulties rather than compare the child harshly with classmates.
School choice is a practical relationship between pupil, parents and school staff. A smaller learning environment can allow closer monitoring, but the family should still check that teachers and specialists can deliver the needed support and that the child feels respected and included.
Frequently asked questions about Integrated International School
Is IIS an ordinary Singapore MOE Secondary 1 school?
No. Integrated International School uses direct private-school admissions and does not have a normal PSLE Posting Group cut-off.
What curriculum does the school use for secondary age?
British-based Lower Secondary Grades 7–9, followed by Pearson Edexcel International GCSE in Grades 10–11, with later A-Level routes described on its site.
What are the 2027 annual course fees?
S$37,000 mainstream or S$45,000 mainstream with support, both GST-inclusive, before certain separately charged items.
Does the quoted 1:6 ratio guarantee every class has six students?
No individual class-size guarantee should be assumed. Ask how the school’s published staffing ratio applies to the specific grade and subject.
Are specialist therapy services included in the course fee?
Some support is integrated, but the official fee page says external therapy and other services may be charged separately. Ask for the written individual support quotation.
Does a Singapore citizen need MOE permission?
Families should verify the relevant foreign-system-school exemption requirements and keep any ordinary local-school obligations in order until a valid alternative is confirmed.

Final parent decision: IIS may be worth considering when its curriculum, learning support, fee arrangement and city-centre journey suit the individual child, and the family has a legitimate admission route. An invented PSLE cut-off or general promise of inclusion cannot replace a careful individual discussion.
