S1Tracker data and evidence
This page separates the allocation cycle, annual dates, official profiles, non-official estimates, exam evidence and third-party references. Every layer retains its own year, source, use and limits.

2025/2027
Allocation cycle and annual timetable
The EDB SSPA 2025/2027 leaflet supplies the key dates, separately from the circular and year-labelled 2024/2026 mechanism references. Only exact current-cycle dates enter the timeline.

- Participating-school list: Not verified
- Non-participating DSS list: Not verified
Guide-to-source map
Evidence used by each of the five guides
Each card separates the decision a guide can explain, evidence still pending for this cycle, and the current-cycle circular, year-labelled mechanism references and annual publication monitor.
Discretionary Places
Use it to understand: Identify the participating-school DP route and separate the two preference orders, interview, successful notification and formal allocation.
Still pending for this cycle: The 2025/2027 participating-school list, school DP place figures and detailed application notes.
6 official sources: 3 current-cycle confirmation or guidance, 2 year-labelled mechanism reference(s), and 1 annual publication monitor.
Open the guide and source recordCentral Allocation Part A
Use it to understand: Understand how the three unrestricted choices are processed before Part B and what the preference order means in practice.
Still pending for this cycle: The 2025/2027 Part A territory-wide school list, paper submission deadlines and detailed parent notes; electronic submission dates depend on the stated conditions.
5 official sources: 2 current-cycle confirmation or guidance, 2 year-labelled mechanism reference(s), and 1 annual publication monitor.
Open the guide and source recordCentral Allocation Part B
Use it to understand: Understand how the applicable school net, up to 30 choices, preference order and choice coverage shape Part B processing.
Still pending for this cycle: The 2025/2027 Part B school-net lists, cross-net arrangements, paper submission deadlines and detailed parent notes.
5 official sources: 2 current-cycle confirmation or guidance, 2 year-labelled mechanism reference(s), and 1 annual publication monitor.
Open the guide and source recordNon-participating DSS
Use it to understand: First establish whether a school is NDSS in the current cycle, then separate school-by-school applications, offers and the consequences of formal acceptance.
Still pending for this cycle: The formal 2025/2027 NDSS list and each school's application, interview, result and place-acceptance deadlines.
6 official sources: 3 current-cycle confirmation or guidance, 2 year-labelled mechanism reference(s), and 1 annual publication monitor.
Open the guide and source recordSSPA e-Platform
Use it to understand: Distinguish account activation, drafts, iAM Smart+ signing, SUBMITTED status, acknowledgement email and later result access.
Still pending for this cycle: Detailed 2027 platform instructions and school paper-submission arrangements; key dates and the conditional electronic CA submission window can now be checked.

441 official secondary-school profiles
Traditional Chinese and English open data are joined only where telephone, normalized official website and founded year match exactly. All 441 keys are unique and no fuzzy school-name match is used. These fields support comparison of district, finance type, fees, language, staffing and facilities, but are not 2027 application status.
- Facts generally as at September 2025.
- Profile S1 admission reference: September 2026.
- Both language files contain 441 rows and 103 fields, with SHA-256 locks.
2026
Non-official academic estimate and exam evidence
The estimate combines 50 points for official-profile academic programmes, 35 for teaching resources and a capped 15-point public-attention proxy. Groups 1A, 1B, 2A, 2B and 3 represent only this model order, not EDB banding, a complete exam ranking, intake results or admission probability.
The source requested 60 recent days; this release measures 2026-05-17 to 2026-07-14, observed 2026-07-15. 409 schools have complete measurements; 29 have no matched article and 3 have an exact or redirected article without complete daily data. Those last two cases give 32 schools a neutral value.
Official-site discovery found 386 candidate pages, but the reviewed comparable academic metric count remains 0. There are also 5 reviewed school-published HKDSE/IB distinction records across 4 schools; incomplete coverage keeps them separate and non-scoring.
Rights and independence
Third-party banding remains external-link only
Schooland and BigExam school-level band values are not copied, stored, filtered or added to School structured data. Schooland pages directly display a BigExam reference, so the two cannot be averaged as independent signals.
Rights boundary reviewed 2026-07-15; publication mode: external_link_only.
School relationships
Through-train, direct and linked relationships do not score
The current release has 30 official-profile-supported P1/S1 page relationships using exact names, self-reference or a reviewed alias; fuzzy matching is prohibited. A relationship does not mean automatic progression, guaranteed places, admission probability or a 2027 arrangement, and scores zero in the academic estimate.
JSON
Machine-readable public files
Files contain only public, aggregate or already-published data, with no student, application, account or document content.
AI discovery catalog
A predictable index of supported public tasks, bilingual entry points, route templates, evidence files and answer boundaries; it does not turn unpublished facts or third-party school values into answers.
JSONEvidence manifest
Cycle, data versions, scoring boundaries, rights, privacy and public artifact endpoints.

Components, model order, rough groups and method version for 441 schools.

Read methodologyFrequently asked questions
Do the published key 2027 dates confirm every school’s application route?
No. The EDB leaflet confirms key application, successful-notification, allocation-result and registration dates. School participation still requires current-cycle lists or an explicit school notice.
Are the 441 school profiles 2027/28 admission data?
No. They are official 2025/26 Secondary School Profiles, generally reflecting September 2025; their S1 admission field applies to September 2026.
Are the 1A-to-3 rough groups EDB banding?
No. They are S1Tracker's non-official academic-led estimates, not student allocation bands, official school ratings, intake results or admission probability.
Why do discovered HKDSE or destination pages not score?
Each candidate still requires review of year, metric, value, unit, denominator and cohort. The current reviewed comparable metric count is zero, so page presence is not treated as an outcome.
