DSE vs IB vs IAL: choosing a route

The three main post-16 curricula for HK students — local DSE, the IB Diploma and British A-levels — compared by structure, grading, assessment and fit.

At a glance

	DSE	IB (IBDP)	IAL / GCE-AL
Structure	4 core + 2–3 electives (plus M1/M2, ApL)	6 subjects (3 HL + 3 SL) plus TOK / EE / CAS core	3–4 subjects studied in depth (linear or modular)
Grading	Levels 1–5 with 5* / 5**; Citizenship reported as attained	45-point scale (7 per subject + 3 core)	A*–E
Assessment	Exam-centred with SBA components in some subjects	Continuous: internal assessments plus global final exams	Edexcel IAL modular with multiple exam windows; CAIE linear AS/A2
University entry	Main route is JUPAS (332A); widely accepted overseas	JUPAS non-DSE route plus mainstream overseas acceptance	JUPAS non-DSE route plus mainstream overseas acceptance
Suits	Strong exam takers aiming at local universities	Broad, expressive and research-minded students	Depth-focused students with clear strengths

Note: since the 2010 medium-of-instruction fine-tuning, many local schools run mixed models — check subject-level MOI rather than a single EMI/CMI label (the school database will list this per school).

The three curricula

DSE

The HKDSE is the mainstream route in local schools: four core subjects plus 2–3 electives. Written exams run April–May (2027: 6 April – 3 May); results feed JUPAS for local universities, with broad overseas recognition.

IB (IBDP)

The IB Diploma, run by international schools and some DSS schools: six subjects across language, sciences, humanities and maths, plus TOK, the extended essay and CAS — breadth and research training are its signature.

Official: IBO ↗

IAL / GCE-AL

British A-levels, common in HK private/international schools: 3–4 subjects in depth for students with a clear direction. Edexcel IAL's modular units spread the exams; CAIE is linear AS/A2. The mainstream ticket to UK and Australian universities.

University entry and switching

All three routes lead to local universities: DSE via the main JUPAS route; IB and A-level applicants use the JUPAS non-DSE route or apply directly (Non-JUPAS); overseas universities accept all three. Switching tracks mid-secondary is possible but needs early planning on credits and language requirements — discuss with the school.
