ExploreAbout this exam
The HKIA/ARB Professional Assessment is the professional assessment route administered in Hong Kong by The Hong Kong Institute of Architects (HKIA) together with the Architects Registration Board (ARB). It sits between an accredited architectural qualification and registration: the ARB registration page states that applicants who have met the qualifications set out in section 13(1) of the Architects Registration Ordinance (Cap. 408) may apply to become a Registered Architect. The assessment is therefore aimed at graduates of HKIA/ARB accredited programmes and at Non-Local Architectural Professionals (NLAP) who need to demonstrate professional competence before registration.
The HKIA site lists the assessment structure under its Professional Assessment menu: eligibility, assessment components, registration, the HKIA/ARB e-Self Service, case study, examiners' reports, a lecture and seminar series, a study guide with sample questions, a publication and open book list, and a list of Professional Assessment Advisors. Candidates should treat the Professional Assessment Handbook as the controlling document for component rules and the current Notice and Announcement page for administrative updates. Preparation should combine the handbook and study guide, the open book list, past examiners' reports, the case study material and the lecture and seminar series. Professional conduct content should be read against the ARB Code of Professional Conduct and the Architects Registration Ordinance (Cap. 408). This page is independent study material and is not affiliated with, endorsed by, or published by HKIA or ARB; always confirm current requirements on the official sites.
What you'll study
About HKIA/ARB PA Paper 4 preparation
Who administers the Professional Assessment and who registers architects?
The assessment is run under HKIA together with the Architects Registration Board. Registration itself is an ARB function: the ARB site invites applications from those who have met the qualifications in section 13(1) of the Architects Registration Ordinance (Cap. 408). Check both official sites, since each publishes different parts of the process.
Where do I find the official rules on eligibility and assessment components?
The HKIA Professional Assessment section lists Eligibility and Assessment Components alongside a Professional Assessment Handbook and a Notice and Announcement page. Treat the handbook as the controlling document for component rules and the notice page for administrative changes. This page is independent study material, so verify every requirement against those official pages before you rely on it.
What preparation resources does HKIA publish?
The listed preparation items are a Case Study, Examiners' Report, a Lecture and Seminar Series, a Study Guide and Sample Questions, a Publication and Open book list, and the HKIA/ARB List of Professional Assessment Advisors. Use the sample questions to learn the expected answer style, and the examiners' reports to see how performance is judged.
Is there a route for architects qualified outside Hong Kong?
Yes. HKIA lists a separate Non-Local Architectural Professional (NLAP) section covering Eligibility and Assessment Components. If you qualified overseas, start there rather than with the standard route, because the eligibility evidence and the components you sit may differ. Confirm your position against the official NLAP pages before enrolling.
Does the assessment cover professional conduct and the law?
Expect it to. ARB publishes the Architects Registration Ordinance (Cap. 408), the ARB Code of Professional Conduct, guidance on Use of "Architect" Title, and a Complaints section. Conduct, title use and the statutory framework are therefore core reading, not background. Read the ordinance and code directly rather than relying on summaries.
How should I sequence my study?
Start with the handbook and eligibility rules so you know which components apply to you. Then work through the study guide and sample questions, read the examiners' reports for judgement standards, and build the open book list into your revision. Attend the lecture and seminar series, and use the advisors list if you need guidance on approach.
What are the most common failure modes?
Candidates typically lose marks by answering from memory instead of the handbook's required structure, ignoring the examiners' reports, and under-preparing the case study. Weakness on the Code of Professional Conduct and the ordinance is also costly. Confirm the current component rules on the official notice page, since administrative details change between cycles.
How do I keep track of deadlines and administrative updates?
Use the HKIA Notice and Announcement page and the ARB News and circulars. ARB publishes numbered circulars, for example ARB/17/2026 on the HKIA/ARB Professional Interview Incident dated 2026-07-14, and has confirmed its website, RA login area and registration system are fully operational after a cyberattack. Always check the latest circular.
Can I contact ARB directly with a question?
Yes. ARB lists email [email protected], telephone +852 3155 0420, and an address at 19th Floor, One Hysan Avenue, Causeway Bay, Hong Kong. Counter service runs Monday to Friday 9:00AM to 6:30PM and Saturday 9:00AM to 12:00NN. Its online enquiry form covers registration, renewal and related subjects.
