The short version

The short version

SISD is a full IB continuum school for ages 3 to 18 in Dubai Healthcare City Phase 2 (Al Jaddaf), founded in 2015 and owned since July 2023 by Nord Anglia Education.

Its defining feature is structural bilingualism: from Pre-KG to Grade 10 students learn in an English-French bilingual stream, an English-German bilingual stream, or an English STEAM stream, with bilingual and advanced bilingual IB Diploma options at the top of the school.

It is the only school in the UAE offering a fully bilingual IB continuum, and one of only two boarding schools in Dubai.↗↗

For an expat family, the practical summary is this: SISD is a specialist choice, not a default one. For Francophone or German-speaking families — or those deliberately raising bilingual children within the IB — nothing else in Dubai matches the offer.

For everyone else, the Very Good (not yet Outstanding) inspection record, premium-plus fees and reported parent-survey softness argue for a careful visit rather than a reputation-based application.

What the school is

Swiss roots, IB spine, new owners

The school’s Swiss identity is linguistic and cultural rather than curricular — the spine is the International Baccalaureate, with the bilingual streams doing the Swiss work.

In the early years and primary, children learn in English, French-and-English, or German-and-English; in the middle and secondary years they choose their language of instruction subject by subject, with the flexibility to change annually. The Grade 11-12 IB Diploma and Career-related Programme are taught in English.↗

Ownership changed in July 2023 when Nord Anglia Education acquired the school from its founder, Omar Danial — its second Dubai campus alongside Nord Anglia International School Dubai. The practical consequences are group-level: access to Nord Anglia’s UNICEF, Juilliard, MIT and IMG Academy collaborations, its Global Campus platform and its professional-development machinery.

Nord Anglia itself was acquired by an EQT-led consortium at a USD 14.5 billion valuation in March 2025 — context for how the group is capitalised rather than something a parent will feel day to day.↗↗

The campus is a genuine differentiator: 70,000 square metres purpose-built to Swiss ecological building standards, with boarding houses, an Olympic-sized pool, a 600-seat auditorium and STEAM labs.

Boarding — full or weekly, from Grade 6 — makes SISD one of only two boarding options in the emirate and the only one inside the city’s central corridor.↗↗

Academics in practice

Results, benchmarks and the transparency question

The school’s 2024 IB Diploma average was reported as 33.2 points against a world average of 30.3 — the school’s own site rounds this to 34 — with a 100% pass rate across Diploma and Career-related entrants from a cohort of roughly 70.

In the 2023 e-MYP assessments, students averaged 41 of 56 against a world average of 38, with 67% earning the bilingual certificate.↗↗

SISD also submits to external benchmarking uncommon among Dubai schools: its TIMSS results reached the High International Benchmark, and its PISA scores were reported above both the Dubai private-school average and Switzerland’s national score.

One honest caveat from WhichSchoolAdvisor’s long coverage: the school has historically been reluctant to publish full Diploma results tables, sharing averages without cohort detail — ask for the complete multi-year table, with cohort sizes, on your visit.↗

The KHDA trajectory is upward but incomplete: Acceptable at the first inspection in 2018, Good in 2019 and again in 2022-23, then Very Good in 2023-24 — the most recent full cycle before Dubai’s two-year inspection pause.

That inspection rated curriculum design and health and safety Outstanding, praised the bilingual provision, and kept Arabic and Islamic Education at Good — the familiar pressure point for international-curriculum schools in the emirate.↗

Admissions and cost

Admissions, fees and the calendar

The published 2025-26 bilingual-stream day fees run from AED 68,868 in Pre-KG to a KHDA-approved AED 137,736 in Grades 11-12 — but the school applies a “community approved discount” that reduces the billed figure to AED 100,976 (Grades 6-8), AED 109,205 (Grades 9-10) and AED 114,268 (Grades 11-12).

Read that discount as part of the price structure, not a concession: ask in writing whether it continues for your child’s full journey, because the gap between approved and billed fees is large. Dubai’s KHDA has frozen tuition for 2026-27.↗↗

Boarding is priced separately and steeply: full boarding runs AED 237,475 to AED 254,968 per year depending on grade, weekly boarding AED 198,625 to AED 216,118.

The English STEAM stream’s day fees sit below the bilingual table per aggregator records, but the school’s own published figure for that stream could not be verified in this pass — confirm both streams’ current schedules directly with admissions.↗↗

Reported teacher turnover of 21% is on the high side for a premium school and worth probing alongside the Nord Anglia integration: ask what has changed operationally since 2023, and how many of your child’s likely teachers pre-date the acquisition.↗

The family experience

Location, community and the daily reality

Al Jaddaf sits on the Creek between Downtown and the airport — genuinely central, and practical for Business Bay, Downtown, DIFC, Festival City and Mirdif-side families in a way the Al Barsha school cluster is not.

France is reported as the largest student nationality, which tells you the bilingual stream is the school’s centre of gravity; the largest teacher nationality is British.↗↗

Parent sentiment is the honest soft spot. WhichSchoolAdvisor’s parent survey scored the school 2.6 of 5 across 37 respondents — a small, self-selecting sample the reviewer itself cautions against over-reading, and in tension with the KHDA’s Outstanding rating for the school’s partnership with parents.

Read both, then do the only thing that settles it: attend a coffee morning or open day and ask current parents directly about communication, turnover and the post-acquisition transition.↗

Our readConfidence: Medium

A unique bilingual offer with a still-maturing record

SISD’s documented strengths are real: the UAE’s only fully bilingual IB continuum, credible external benchmarks (TIMSS, PISA) that most schools never submit to, a rising KHDA trajectory, an exceptional purpose-built campus, Dubai’s only central boarding option, and the resources of the world’s largest premium-school group behind it.

Our confidence is Medium because this edition is document-based, results transparency is limited (averages without cohort tables), some headline claims conflict between the school and its reviewers, and the English-stream fee schedule could not be verified first-party.

The fit question is unusually sharp. For Francophone and German-speaking families, and for parents committed to bilingual IB education, SISD is effectively the only answer in Dubai — and a good one.

For families shopping on inspection ratings alone, Very Good sits a tier below the Outstanding schools in this series, and the combination of ultra-premium fees, 21% reported turnover and mixed survey sentiment says the school is still consolidating.

The discount structure deserves particular scrutiny: the billed fee is far below the KHDA-approved fee, which is fine while it lasts — get its duration in writing.

Questions that move beyond the tour script

Admissions and language streams

  1. How are children placed into the bilingual versus English streams, and what language profile does each stream assume at our child’s entry age?
  2. How does subject-by-subject language choice work in the secondary years, and can a child move between streams mid-school?
  3. What does the bilingual or advanced bilingual IB Diploma require, and how many current Diploma students are on track for it?

Academics and support

  1. May we see full IB Diploma and CP results for the last three years — cohort sizes, pass rates, grade distributions — not just averages?
  2. How are Arabic and Islamic Education being strengthened from their current Good ratings?
  3. What has changed in staffing and leadership since the Nord Anglia acquisition, and what is current teacher turnover?

Cost and logistics

  1. Is the community discount guaranteed for our child’s full school journey, and what were the billed fees for our stream and grade in 2026-27?
  2. What does boarding cost in total — fees, weekend programmes, exeat logistics — and how many boarders are there per house?
  3. Beyond tuition, what should we budget for application, registration, uniform, transport, devices and trips in year one?
