Secondary International Schools in Jakarta for Expat Families

For families with teenagers, a Jakarta posting raises specific educational concerns: will the curriculum align with where we are heading next? Will university applications be affected? Can my child join mid-way through a secondary programme without losing ground?

Jakarta's international secondary schools are well-experienced in answering these questions. The city has been a major expat hub for decades, and its schools have adapted to serve students who move in and out at various stages of their secondary education.

The Secondary Landscape

The majority of Jakarta's leading international secondary schools now follow the International Baccalaureate pathway — IB Middle Years Programme (Years 7–11, age 11–16) followed by IB Diploma (Years 12–13, age 16–18). This provides a coherent, internationally portable curriculum recognised by universities in the UK, USA, Australia, and across Europe.

A smaller number of schools offer Cambridge IGCSE as the middle school qualification, with either Cambridge A-Levels or the IB Diploma at Sixth Form level. For families specifically seeking IGCSE and A-Level qualifications, see our dedicated GCSE and A-Levels Jakarta guide.

Leading Secondary International Schools

Jakarta Intercultural School (JIS) — Grades 6–12

JIS secondary covers Grades 6–12 (age 11–18). The school uses the IB Middle Years Programme and IB Diploma, taught within an American-influenced framework. JIS is one of the most academically well-resourced international schools in Indonesia — its secondary campus has specialist science laboratories, a university counselling centre, and co-curricular programmes spanning performing arts, athletics, and community service.

Annual secondary fees at JIS range from approximately IDR 370–600 million, making it the highest-cost option in Jakarta. The school draws students from more than 60 nationalities, and its Diploma results have historically been competitive with global IB averages.

JIS is particularly well-suited to families planning to apply to North American universities, given its American curriculum roots, though its IB Diploma pathway also supports strong UK university applications.

British School Jakarta (BSJ) — Years 7–13

BSJ secondary runs from Year 7 to Year 13, covering the IB Middle Years Programme (Years 7–11) and IB Diploma (Years 12–13). The British National Curriculum background at primary gives BSJ students a strong foundation in literacy and structured academic writing.

BSJ is widely regarded for its pastoral care, with a tutor system and robust university guidance provided through its University Hub. University placements have included Russell Group institutions, top Australian universities, and growing numbers to the USA. Annual secondary fees range from approximately IDR 280–411 million (Year 12–13).

External applicants to Sixth Form (Year 12) require a minimum of three A grades and three B grades at IGCSE or equivalent — the school applies an academic entry threshold.

ACG School Jakarta — Years 7–13

ACG School Jakarta follows Cambridge Lower Secondary and IGCSE for Years 7–11, transitioning to the IB Diploma in Years 12–13. This gives ACG students an IGCSE qualification — a formal external credential at age 15–16 — before proceeding to the IB Diploma. This can be an advantage for students who may need to demonstrate a traditional GCSE-equivalent record.

ACG's smaller size gives it a more personalised feel than JIS or BSJ, with closer teacher-student relationships in the secondary years. It is a well-regarded option for families seeking a coherent K–13 pathway with clear external qualifications at each stage.

Sekolah Pelita Harapan (SPH) — Secondary

SPH offers secondary education across several campuses, blending Cambridge curriculum and IB Diploma options. Its Christian faith ethos is maintained throughout secondary, and the pastoral structure reflects this. For mixed Indonesian-international families, SPH secondary combines an international academic standard with greater cultural integration with the Indonesian context.

Bina Bangsa School (BBS) — Secondary

BBS secondary uses the Cambridge International curriculum through IGCSE level, with strong results in English, Mathematics, and Science. The Singapore curriculum influence brings a rigour in mathematics that some families find appealing. For students heading to Singapore universities or seeking strong STEM preparation, BBS is worth considering.

BBS fees remain among the most accessible, making it a realistic option for families with multiple secondary-age children or those without full employer fee support.

Joining Mid-Secondary: What to Expect

Joining a Jakarta international school at secondary level — particularly from a different curriculum system — requires some planning:

At Year 7 (age 11–12): The most natural entry point. Most schools have structured transition programmes.

At Year 9 (age 13–14): Possible at all main schools, though some assessment will be required to confirm appropriate subject level.

At Year 10 (IGCSE / MYP Year 4, age 14–15): Manageable but requires discussion with the school about subject selection and any bridging requirements. Two-year IGCSE programmes effectively restart here.

At Year 11 (final IGCSE/MYP year, age 15–16): Generally not advised for mid-year entry. Schools may accommodate August starts.

At Year 12 (IB Diploma, age 16–17): Possible with academic entry requirements met. Subject group requirements must be planned carefully to meet university prerequisites.

For detailed guidance, see our applying to international school in Jakarta guide.

Co-Curricular and University Preparation

Jakarta's international secondary schools take co-curricular activity seriously — both as part of the IB's CAS (Creativity, Activity, Service) requirement and as enrichment in its own right. Families can expect:

• Competitive sports programmes (football, swimming, basketball, badminton)
• Performing arts (drama, music, dance)
• Model UN, debate, and student council
• Duke of Edinburgh's International Award (at some schools)
• Community service partnerships with Jakarta-based organisations

For university-bound students, dedicated university counselling is available from Year 11 at the main schools. See our university admissions from Jakarta international schools guide for detail on UCAS, US college applications, and UK fee status.

Summary: Secondary School Comparison

MYP or IGCSE: What the Choice Actually Decides

The most consequential curriculum decision at Jakarta secondary level is the one described above — whether the middle years run on the IB Middle Years Programme or on Cambridge IGCSE. Families often treat this as a technicality. It is not.

The practical difference is what your child holds in their hand at sixteen. An IGCSE course produces external, externally marked certificates from Cambridge. The MYP, as noted above, is generally used internally at Jakarta schools and leads into the Diploma without an external certificate at that point. If the family stays put and the child continues to the IB Diploma at the same school, this rarely matters: universities admit on Diploma results, and admissions offices are entirely familiar with applicants who came through the MYP.

It begins to matter in three situations. Where the family may return to a system that expects GCSE-equivalent results — for a UK sixth form or independent school place, for instance — an external qualification is simpler to present. Where the child may move to a school that does not offer the Diploma, a formal record at sixteen provides a common reference point. And where a child's academic profile is uneven, an external certificate can evidence strength in specific subjects in a way an internal record does not.

None of this makes one route superior. It makes the route a function of how confident you are about the next few years, which is precisely the thing internationally mobile families are usually least certain about.

Preparing for Entry Assessment

The entry points set out above almost always involve some form of assessment. Understanding its purpose reduces the anxiety around it considerably: at most Jakarta international schools the assessment is used to place a child correctly and to identify what support they will need, not to rank applicants against one another. Schools want to know whether a student can access the curriculum in English and where they sit in mathematics relative to the year group.

Practical preparation is therefore mostly administrative. Gather school reports covering the last few years, any external examination results, and documentation of any learning assessment already carried out — the last of these in particular, since support provision varies by school and cannot be arranged retrospectively at short notice. Where your child is joining from a different curriculum, ask the school which topics the incoming year group has already covered, so that gaps are identified before term begins rather than in the first assessment week.

Three Questions the Prospectuses Do Not Answer

Most of what a family needs is set out above or in the guides linked from it. Three things are not, they vary sharply between the schools in the table, and none of them appears in a brochure.

Which Diploma subjects have actually opened in each of the last few years, and what is the minimum cohort size? Jakarta's international schools are not large by global standards, and a Higher Level subject listed in a prospectus runs only if enough students choose it in that particular year. For a student with a settled direction — medicine, engineering, a specific language — a pathway that exists on paper but has not run for two years is not a pathway. Ask for the years, not for the list.

What are the realistic door-to-door journey times from the areas you are considering, and how late do co-curricular activities run? Jakarta traffic makes this the question that quietly decides which schools are genuinely available to you, and the answer bears little relation to distance on a map. It also decides whether your child can join anything that finishes after the last bus, which is where most of the friendships form. Our guide to the best areas in Jakarta near international schools covers the geography.

What happens to a student who does not meet the entry requirement for the Diploma? Schools that apply an academic threshold for progression into Year 12 — and several here do — have a settled answer, whether that is an alternative pathway, a repeated year, or a frank conversation about moving on. It is a far better answer to have in Year 9 than in Year 11.

Thinking About the Cost Trajectory

The comparison table above shows secondary fees, not the whole commitment. Fees rise between year groups, examination entry costs attach to the Diploma years, and university-application costs — test registrations, admissions tests, application fees and visits — cluster in the final two years, at exactly the point tuition is at its highest. For families with more than one teenager, those peaks can overlap.

The fee tables here are quoted in rupiah while most internationally mobile families earn in another currency, which puts an exchange rate between your income and your school bill for the length of the posting. Where a school allows fees to be settled annually rather than termly, weigh the discount, if there is one, against the effect of converting a larger sum at a single rate.
