The headline shift in six numbers

Six numbers describe the period most concisely. Hong Kong's international school enrolment peaked at around 48,000 in 2019, fell roughly 7 to 9 per cent by 2022, and has recovered to within 2 per cent of the peak by the start of the 2025 to 2026 academic year. ESF aggregate enrolment dipped 5 to 6 per cent between 2020 and 2023 and has been broadly flat since. Through-train flagship enrolment held within 1 per cent of capacity across the whole period. Debenture transaction volumes at HKIS, CIS and GSIS halved between 2020 and 2022, then doubled back by 2025. Tuition has compounded at an average 4.6 per cent per year, with sharper rises in 2023 and 2024. The international cohort is materially less British in composition than it was in 2019 and materially more mainland Chinese and South East Asian.

None of those numbers tells the full story alone. Read together, they describe a market that contracted, partially relocated, then reabsorbed demand from a different mix of families. For the pillar view of where things stand today see our best international schools in Hong Kong guide and the Hong Kong city page.

Who left, who stayed and who arrived

The departures of 2020 to 2022 were not random. The departing families skewed British and Australian, concentrated in financial services and law, and over-represented in mid-cohort year groups (Years 6 to 10). Those families left because of a combination of pandemic policy, schooling continuity, BNO eligibility and personal risk assessment. Many took up places in the UK private system, in Singapore, in Sydney and increasingly in Dubai. A smaller stream went to Bangkok and Kuala Lumpur. The departures were felt sharply at ESF Year 9 and Year 10 and at the British-curriculum independents.

The arrivals of 2022 to 2025 came from a different distribution. Mainland Chinese families relocating with EP3 dependants, returnees from Singapore who had outgrown its capacity, and South East Asian families newly attracted by the rebound in regional headquartering. Hong Kong also saw a partial return of departed families whose Singapore housing costs proved punishing, particularly those without employer-funded housing allowances. The net result by 2025 is a school cohort that looks more regional and less Anglospheric than at any point since the 1990s.

Composition snapshot, 2019 vs 2025. British and Australian passports as a share of international school cohort: roughly 24 per cent in 2019, roughly 16 per cent in 2025. Mainland Chinese and South East Asian: roughly 28 per cent in 2019, roughly 38 per cent in 2025. Other (American, European, South Asian, Korean, Japanese): broadly stable around 40 per cent. Estimates aggregated from school annual reports and EDB statistics.

ESF rolls and the year-group asymmetry

ESF's aggregate roll across its 22 schools and kindergartens softened by 5 to 6 per cent between 2020 and 2023, then stabilised. The headline number conceals a year-group asymmetry that matters for families applying in 2026. The contraction was concentrated in Years 7 to 11 at the secondary schools (Island, South Island, West Island, King George V, Sha Tin College, Discovery College). Year 1 entry at the primaries (Bradbury, Beacon Hill, Glenealy, Kennedy, Quarry Bay, Sha Tin Junior, Clearwater Bay) tightened earlier and is again at the long-standing point of high competition.

The implication for relocating families is straightforward. A family applying for Year 9 at an ESF secondary in 2026 will probably find at least a waitlist position, sometimes immediate availability. A family applying for Year 1 will face the historic ESF reality of meeting the priority categories or accepting a longer wait. Sibling priority remains the strongest single variable. For the structural background see our best primary international schools in Hong Kong piece.

Through-train demand: HKIS, Harrow, CIS, GSIS

The through-train flagships came through the five-year period in markedly different shape from ESF. Hong Kong International School (HKIS), Chinese International School (CIS), German Swiss International School (GSIS) and Harrow Hong Kong all held within 1 per cent of capacity through the entire window. Two factors explain the resilience. Their cohorts were less concentrated in the departing British financial services demographic, and their through-train structure binds families across more years, smoothing roll volatility. HKIS's deep American cohort, in particular, weathered the early period without significant exits.

The consequence is a market where the through-train schools have become relatively more competitive over time, not less. A Year 1 place at HKIS or CIS in 2026 is, if anything, harder to secure than in 2019, because the supply did not expand while demand softened only marginally at the very top tier. For families on a Hong Kong landing in 2026, the through-train pathway requires earlier application, debenture preparedness and a candid view on the realistic admission probability.

Debenture market split and what it tells us

The most informative single signal of Hong Kong school demand is the secondary market in school debentures. Through 2020 to 2022, both individual and corporate debenture transaction volumes fell roughly 50 per cent at HKIS, CIS, GSIS and the larger British schools. Secondary market prices softened materially, particularly for corporate debentures at HKIS. By 2024 the market had bifurcated. Individual debentures at HKIS, CIS, GSIS and the strongest British schools had recovered to or above 2019 nominal prices. Corporate debentures softened further, then partly recovered, then settled at a discount to individual debentures wider than the historical norm.

The split tells us two things. First, family demand for the top through-train schools has fully returned and is again capacity-constrained. Second, corporate sponsorship demand, which was historically a smoother stream tied to relocation packages, has not fully returned to 2019 levels. The latter reflects employer policy changes: more employers now cap education allowances or shift to lump-sum relocation grants, reducing reliance on the corporate debenture market. Families negotiating relocation packages in 2026 should price this in. The Hong Kong international school fees guide covers the latest debenture and capital levy detail.

Fee inflation and where parents pushed back

Hong Kong international school tuition has compounded at an average 4.6 per cent per year across 2020 to 2026, slightly faster than the historical 3 to 4 per cent baseline. The largest rises were taken in 2023 and 2024, when most schools rebuilt margins eroded by enrolment dips and currency adjustments. Parents pushed back in those years in three observable ways. Some schools introduced fee freezes or below-inflation rises in 2025 in response to parent feedback. The compare-school behaviour of relocating families intensified, with the average Hong Kong family now contacting four to five schools before committing rather than two to three in 2019. Mid-tier schools that had drifted close to flagship pricing without commensurate outcomes saw their applicant pools shrink fastest.

The honest implication for 2026 to 2027 budgeting is that the all-in cost (tuition plus capital levy plus extras) at a Hong Kong Tier 1 school now runs HKD 220,000 to HKD 320,000 per child per year, with debenture refundability separate from that. Families should set expectations against that range when negotiating relocation packages. For city-by-city benchmarking see the fees explorer tool and our comparative piece on Hong Kong versus Singapore schools.

Mainland Chinese demand and the Greater Bay reset

The single largest demographic change is the rise in mainland Chinese family demand. The Top Talent Pass Scheme, the expansion of EP3 dependant places, and the gradual normalisation of Hong Kong as a Greater Bay Area education centre have all combined to push mainland family enrolment up. The lift has been concentrated at the bilingual and Putonghua-strong schools (CIS in particular, with its 50 per cent Chinese stream), and at the IB-track schools whose curriculum offers a globally portable post-Hong Kong pathway. The arrival has steadied total demand in a window when other cohorts contracted, and has reshaped the typical class composition at several flagships.

The schools that gained most are those that combine credible English-medium delivery with an authentic Chinese-language and culture programme. The schools that struggled most are those without any Chinese language depth and dependent on the British financial services cohort. For families weighing whether Hong Kong is the right Asia base, our moving to Hong Kong with children guide sets out the broader relocation picture.

Capacity, openings and the schools that contracted

Two new international schools opened in Hong Kong during the period: Malvern College Hong Kong (which scaled up its primary and secondary intake), and Mount Kelly International School (primary). One smaller school, Hong Kong Academy, restructured and reduced its secondary enrolment in 2023. The Norwegian International School maintained roll. ESF closed no schools but rebalanced internal capacity across its network. The net capacity change across the system is roughly flat, perhaps slightly positive on a Year 1 to Year 13 basis.

The capacity story matters more than it sounds. The departures of 2020 to 2022 created a perception that Hong Kong's school system had become a buyer's market. That perception was only briefly accurate, and only at certain year groups in certain parts of the system. By 2025 it is largely false at the top tier. Families relying on an out-of-date sense of slack will be surprised when they apply.

Implications for relocating families

The practical reading for families landing in Hong Kong in 2026 or 2027 is fourfold. First, treat the through-train flagships as fully capacity-constrained at primary entry and apply at the earliest credible date. Second, expect more flexibility at ESF secondary in Years 8 to 11 than at ESF primary in Years 1 to 4. Third, do not assume that fee softness has continued; the rebuild years are over and renewals are firmly back. Fourth, the curriculum mix at most schools is more international than five years ago, which is generally positive for the experience but means class composition discussions with admissions teams are worth holding candidly.

A family's best protection against year-group risk is portfolio applying: three Tier 1 schools, one Tier 2 and one realistic back-up, sequenced with the offer-deadline timing in mind. The school comparison tool helps to structure that side-by-side, and the school finder tool helps shape an honest shortlist before applications go in.

Outlook to 2028

The base case for the next 18 to 24 months is continued normalisation rather than another disruption. Through-train demand will probably stay tight. ESF secondary year groups in the contraction cohort will gradually refill as the Years 5 to 10 children of new arrivals work through the system. Fees will continue to rise in the 4 to 5 per cent range. The mainland cohort share will probably continue rising at a slower pace than the headline 2022 to 2024 period. Capacity is unlikely to expand materially.

The downside scenarios are not negligible but are familiar: a further widening in Hong Kong-mainland policy positioning, a meaningful currency move, or a regional financial services rebalancing towards Singapore could each move the demand picture by 3 to 5 per cent in a single academic year. None of those would change the structural reality that the Hong Kong top tier is supply-constrained and that the most useful posture for relocating families is to apply early, treat debenture markets with caution, and build a shortlist of four to five rather than two.
