Nord Anglia Jakarta vs BSJ — A Detailed Comparison

BSJ is the school most expat families hear about first. It is the largest, oldest, and most visible British-heritage school in Jakarta. ISJ, NAS, and ACG each offer a different version of a British-heritage education at different price points, in different locations, with different trade-offs. This is a side-by-side comparison of all four.

BSJ - The Full-Pathway Establishment

British School Jakarta is the longest-established and largest British-heritage school in Indonesia. Founded in 1974, it occupies a 45-acre estate in Bintaro, a suburb southwest of central Jakarta, technically in Tangerang Selatan. The campus is the largest of any international school in the city and it is not close.

BSJ runs the full pathway from age 2 through to Year 13. Primary follows the Early Years Foundation Stage and the English National Curriculum with an inquiry-based approach. From Year 7, students move into the IB Middle Years Programme. The Sixth Form offers the IB Diploma. This hybrid, British primary, IB secondary, means BSJ is less traditionally British than it once was. The school culture remains British (uniforms, assemblies, house system, character emphasis), but the academic qualifications are international. Students take IB MYP and IB DP, not IGCSEs or A-Levels. If you specifically want British qualifications rather than British culture, clarify this during admissions.

The facilities are exceptional and unmatched by any school in this comparison. An Olympic-sized swimming pool, a 750-seat performing arts theatre, five football fields, twelve badminton courts, five tennis courts, a gymnasium complex, and a new all-weather Arena completed in 2025. The Manchester City Football Club partnership provides professional coaching on campus. The school runs 260-plus extracurricular activities across before-school, lunchtime, after-school, and Saturday slots.

BSJ draws primarily from British, European, and Australian expatriate families, though the community has diversified significantly. Over 50 nationalities are represented. At 1,400 students, BSJ is big enough to offer serious breadth but parents say staff still know their children by name.

The school holds joint CIS/WASC accreditation (reaffirmed 2023, extended to 2028) and is authorised for all three IB programmes. It is a COBIS member and a founding member of FOBISIA. BSJ is currently led by an Interim Principal, many parents are waiting to see who gets the permanent role before judging strategic direction.

BSJ is a non-profit educational trust overseen by a Council of Trustees and a Board of Governors. Tuition revenue is reinvested in the school, into facilities, staffing, and programmes, rather than distributed to shareholders. That reinvestment model, compounded over five decades, is how BSJ built a campus that the three other schools in this comparison cannot match.

BSJ Fees (2025-26)

BSJ charges tuition and a compulsory annual Capital Levy Contribution (CLC) as separate line items. The figures below show both. BSJ is the most expensive school in this comparison at secondary and sixth form level.

Application fee: IDR 5,000,000 (~US$297). Enrolment Fee: IDR 30,000,000 (~US$1,783). A 3% discount applies for annual payment in full. Fees include tuition and compulsory Capital Levy Contribution. Fees do not include extracurricular activities, external competitions, trips, computer/instrument rentals, or personal learning assistants. Bus and cafeteria are invoiced separately by third-party providers.

ISJ - The British Prep School

The Independent School of Jakarta opened in 2022 and models itself on a British independent prep school, not a large international school that happens to follow the English National Curriculum. The distinction matters.

ISJ is operated by The Schools Trust, a group with a long track record of founding British schools internationally. The trust has opened 16 schools across Asia, Europe, and South America since 2004, including The British School of Beijing (Sanlitun and Shunyi), The British School of Guangzhou, The British School of Kuala Lumpur, The British School of Nanjing, The King's School Manila, and schools in Moscow, Yangon, São Paulo, Brasília, Lisbon, Vilnius, Tashkent, Pamplona, and Marbella. These are not franchise operations. They are schools built from scratch to British independent school standards, in teaching and learning, safeguarding, staff development, pastoral care, and the kind of confidence-building and character education that defines the UK independent sector (all Schools Trust schools are required to be UK inspected and BSO accredited).

ISJ's founding head came from Queen's College Preparatory School in London. The current head came from Ipswich High School, an independent day and boarding school on an 87-acre campus in Woolverstone, Suffolk. ISJ sends its top year group pupils to Ipswich High School every year for a two-week residential. That link is not decorative, it is an active partnership that gives ISJ students direct experience of a British boarding school environment.

Every teacher at ISJ holds British teaching qualifications. Class sizes are capped at 15 in Early Years and 20 in Primary. The school currently runs from Pre-Nursery (age 2) through to Year 8 (age 13), following the English National Curriculum. A secondary campus is planned for September 2028, with the intention of taking pupils through to A-levels.

ISJ sits in Pondok Indah, one of the most convenient locations of any international school in Jakarta for families living in the south. The campus is purpose-built and compact. It does not compete with BSJ on scale. What it does offer is a tightly controlled environment where staff know every child, the teaching is consistently British-trained, and the extracurricular programme is broader than you would expect for a school of its size.

The school is a non-profit. Tuition fees include the capital contribution, there is no separate levy. At primary level, ISJ and BSJ are comparable in price. ISJ Year 1-2 fees (~US$24,944) are marginally below BSJ's Year 2 rate (~US$25,285), though BSJ's Years 3-6 have now risen to ~US$26,590. ISJ's upper primary (Years 5-6 at ~US$27,635) runs above BSJ's primary rate. The two schools are neck-and-neck at primary, but BSJ's secondary and sixth form fees climb well above ISJ's current range.

The premium at ISJ buys three things: teacher quality (100% British-qualified is a standard no other Jakarta school matches), class size (20 maximum vs 22 at BSJ), and a school culture rooted in the British independent prep school tradition. Whether that premium is worth it depends on how much weight you put on those three factors, and whether you are comfortable joining a school whose secondary campus is two years away from opening.

ISJ Fees (2025-26)

ISJ bundles tuition, classroom materials, and capital contribution into a single annual fee. There is no separate capital levy.

Application fee: IDR 4,680,000 (~US$278). Enrolment Deposit: IDR 16,328,000 (~US$970), refundable on departure with one term's notice. Sibling discounts: 5% (3rd child), 10% (4th child), 15% (5th+). Bursaries available, assessed case-by-case. Fees do not include uniform, meals, transport, optional clubs, wraparound care, individual music lessons, or trips.

NAS Jakarta - The Affordable Primary with a Global Brand

Nord Anglia School Jakarta has a longer history than most parents realise, though few would guess it. It started in 1967 as the Netherlands Inter-community School, serving Dutch expatriate children from a single classroom in Menteng. It moved through several Jakarta locations before settling in Cilandak, where it occupies a compact campus on Jalan Jeruk Perut. In 2017 it joined Nord Anglia Education and was rebranded.

NAS serves children from 18 months to Year 6, following the English National Curriculum supplemented by the International Primary Curriculum (IPC). At around 200 students and 30-plus nationalities, it is mid-sized, large enough to be properly international, small enough that teachers know every child. Parents describe the community as warm.

What distinguishes NAS on paper is the Nord Anglia network. Eighty-plus schools globally, with structured collaborations with MIT (STEAM challenges), the Juilliard School (performing arts), and UNICEF. Whether those programmes are transformative or decorative in Jakarta depends on how actively this particular campus implements them, worth asking about on a visit.

The campus needs honest discussion. It is in a pleasant Cilandak residential area, but the facilities are aging. The buildings show their years. When heavy rain hits, which in Jakarta means regularly, the entrance to the school floods, and children have been ferried in and out on small boats. A library, a science lab, a maker space, a music room, and green outdoor spaces are appropriate for a primary school. But the campus is not in the same condition as a school with recent investment.

NAS is a for-profit school, owned by Nord Anglia Education, one of the world's largest premium school groups, ultimately backed by EQT, a Swedish private equity firm managing hundreds of billions in assets. NAS Jakarta is one small school in a very large portfolio. The ownership structure means investment decisions are governed by a commercial return calculation, not a community reinvestment mandate. That is not a moral judgement, Nord Anglia schools globally maintain credible standards, but the economics are structurally different from a non-profit trust, and parents sometimes notice the gap between the global brand and the local campus reality.

NAS also runs a unique Dutch Language and Culture (NTC) programme, three hours per week of Dutch instruction for Dutch-passport families. This is the only such programme in Jakarta and reflects the school's heritage.

The secondary question: NAS is expanding to Year 7 in 2026-27. That is one additional year group, not a secondary school. Until NAS publishes a credible multi-year build-out plan with facilities, staffing, and curriculum pathways through to Year 13, families should treat the secondary expansion with caution. Most NAS families currently move to BSJ, JIS, or other secondary schools. Ask directly about the timeline and transition support.

The fee advantage is real. NAS is the cheapest of the four schools at primary level, around US$20,600-$20,900 per year at Years 1-7, roughly 20% below BSJ and ISJ.

NAS Jakarta Fees (2025-26)

NAS does not charge a separate capital levy, tuition is the total annual recurring fee.

Application fee: IDR 4,600,000 (~US$273). Sibling discount: 5% (3rd child), 10% (4th+).

ACG Jakarta - The Full Pathway at Lower Cost

ACG School Jakarta does not come up in most expat conversations about British schools in Jakarta. It deserves to. It is the only school in this comparison other than BSJ that offers a full pathway from Kindergarten to Year 13, and it does so at significantly lower fees across every stage.

ACG sits in Pasar Minggu, south Jakarta, on a mid-sized modern campus. The school runs IB Primary Years Programme (PYP) in the early and primary years, Cambridge IGCSEs in the middle years, and the IB Diploma in the Sixth Form. That hybrid pathway, IB primary, Cambridge middle, IB exit, gives students structured examinations at 16 (IGCSEs) and a globally recognised diploma at 18.

The numbers are small. ACG has around 300 students across all year groups. In senior school, class sizes run at 12-14. The school reported an IB Diploma average of 35 points in 2022, comfortably above the global average of 30-31. That is a strong result for a school of this size, though the small cohort means averages can swing year to year.

ACG is owned by Inspired, a for-profit global education group with a reputation for tight cost management. The lower fees, around US$23,263-$23,675 at primary (Years 3-6, including development fee), are roughly 10-15% below BSJ and ISJ. At senior level (Years 7-10), ACG charges ~US$24,398 compared to BSJ's ~US$30,735. The IB Diploma years cost ~US$24,673, against BSJ's ~US$32,910. Those savings are significant over a school career. But lower fees mean lower budgets, for staff salaries, for teaching materials, for campus investment. That correlation is consistent across international schools globally, and ACG is unlikely to be an exception.

The campus is modern and well-maintained, with science labs, a performing arts space, sports facilities, and a library. It does not have the scale of BSJ. The community is described by parents as warm and inclusive, with non-selective admissions and a genuine international mix.

The trade-off is scale and resources. Three hundred students means fewer extracurricular options, a smaller peer group, and less depth in any one area. If your child is a competitive swimmer or wants to play in a full orchestra, BSJ is the better fit. If your child thrives in a smaller setting where teachers know them well and the academic pathway is strong, ACG deserves a serious look, particularly if the full K-13 pathway matters and BSJ's fees or location do not work.

ACG Jakarta Fees (2025-26)

ACG fees below include tuition plus the compulsory annual development fee (IDR 8,100,000 for Kindergarten, IDR 39,500,000 for Years 1-13).

Application fee: IDR 4,000,000 (~US$238). 2.5% early payment discount if paid in full before May 12. Annual or two-semester payment options. Additional mandatory fees: Residential Learning (Camps) IDR 3.5M-13M/year, Technology Levy IDR 815K-1.63M/year.

The Five Real Differences

The comparison table at the top gives you the data. These are the decisions behind the data.

1. Full pathway vs primary only

BSJ and ACG take children from Kindergarten through to Year 13 and a university-ready qualification (IB Diploma at both). ISJ currently goes to Year 8 with A-levels planned from September 2028. NAS goes to Year 6 with Year 7 starting in 2026-27.

If your child is currently in Year 7 or 8, BSJ and ACG are the only two options here that do not require a school change, ISJ's secondary campus will not be open in time. For everyone in Year 6 or below, ISJ's September 2028 secondary opening means the pathway is there when they need it.

2. What the fees buy: and where the money goes

At primary level (Years 3-6), BSJ and ISJ cost roughly the same: ~US$26,000-$27,600 per year. NAS and ACG sit at ~US$20,800-$23,700. The gap between the two tiers is around US$3,000-$6,000 per year.

BSJ's fees fund a 45-acre campus with facilities no other Jakarta school matches, 260-plus activities, and a guaranteed IB Diploma pathway. The school has had 50 years of compounding non-profit reinvestment to build that infrastructure.

ISJ's comparable fees fund a different model: 100% British-qualified teachers, smaller class sizes (20 vs 22 at BSJ), and a school built from scratch to British independent school standards by a trust with 16 schools behind it. The facilities are more modest, the money goes to people, not property.

NAS and ACG charge less, and that shows up in what they can offer. Lower fees mean lower teacher salary budgets, which means a different applicant pool. NAS offsets this with Nord Anglia's global network and programmes. ACG offsets it with a full K-13 pathway and strong IB results despite tighter resources.

3. Ownership and what it means in practice

BSJ and ISJ are non-profits. Tuition revenue is reinvested into the school. BSJ's five decades of reinvestment built the campus you see today. ISJ's non-profit structure, through The Schools Trust, funds its teacher salary model and campus development.

NAS and ACG are for-profits. NAS is owned by Nord Anglia Education, ultimately backed by EQT, a Swedish private equity firm. ACG is owned by Inspired, a global education group. For-profit ownership is not inherently negative, but the incentive structure is different. Investment decisions are filtered through a return-on-capital lens that non-profits do not have. Parents at for-profit schools sometimes notice this in facility condition, staffing ratios, or the pace of campus investment.

4. Location and the commute

BSJ is in Bintaro, technically Tangerang Selatan, not Jakarta. From Pondok Indah, Kemang, or Cipete, the drive is 25-40 minutes on a good day, longer in the wet season. This is BSJ's biggest practical drawback. Most BSJ families either live in Bintaro or treat the commute as the price of the campus.

ISJ is in Pondok Indah. NAS is in Cilandak. ACG is in Pasar Minggu. All three are in South Jakarta proper, 10-20 minutes from each other and from the main expat residential areas. If you live in South Jakarta and the daily commute matters to you, BSJ is the outlier.

5. Culture and size

BSJ has 1,400 students. NAS has ~200. ACG has ~300. ISJ has ~200. These are not minor differences, they shape the entire experience.

BSJ is big enough to offer serious breadth: competitive sports teams, a full performing arts programme, a wide peer group. ISJ, NAS, and ACG are all small enough that teachers know every child's name, strengths, and struggles, but the peer group is narrower and extracurricular depth is limited.

Parents who want a school that feels like a community tend towards ISJ, NAS, or ACG. Parents who want a school that feels like an institution, in the best sense, with all the resources that scale provides, tend towards BSJ.
