Overseas architecture degree, no ARB Part 1: the three routes, and what each one actually demands

There are three published routes onto the UK Architects Register for someone whose architecture qualification was earned outside the UK. Which one is open to you is decided almost entirely by one question: are you already a registered architect in a country ARB has an agreement with? If yes, you are on the recognition route. If no, you are on the examination route or the study route, and both of those end at the same place — a UK practice-level qualification you still have to obtain.

That last point is the one ARB states and nobody repeats. Its own guidance:

“Once you have satisfied Part 1 and Part 2 requirements, either by obtaining qualifications or by passing the Prescribed Examination, you will then need to obtain a UK Part 3 qualification from a UK school of architecture.”

No route in this article removes that.

Route 1 — The Prescribed Examination (for a degree, not a licence)

This is the route for people who hold an architecture qualification that ARB has not accredited, and who are not registered architects under an agreement partner. ARB describes it as its “Examination for Equivalence to Prescribed Qualifications”.

What it assesses. Not your practice. Your academic work, against ARB’s published Criteria. You submit a Comparative Matrix and a portfolio of Supporting Material, examiners review it in private, and if you clear the threshold you are interviewed. ARB states that on the day “the examiners will spend an hour and a half assessing your Supporting Material” and that “your work must meet at least 17 Criteria in this session to progress to the interview stage.” The interview “will last up to 45 minutes” and is held on Zoom.

What it will not accept. ARB is unusually direct here, and this sentence saves people years:

“ARB is not an academic institution but is a registration body which bases registration on qualifications obtained from academic institutions. It therefore cannot use work experience in lieu of any academic study not obtained.”

Twenty years in an architecture practice does not substitute for the degree you did not take. Office work can form part of your portfolio evidence — ARB says “You are not limited to academic projects, and it is entirely appropriate to include office-based and other material” — but it supports the evidence, it does not replace the qualification.

Eligibility, from the Procedures rather than the web page. Section 2.2.1 of ARB’s Prescribed Examination Procedures says candidates are eligible at Part 1 “if they have gained a non-prescribed qualification in architecture at first degree level after completing a course of at least three years’ full time duration or part time equivalent”. At Part 2, section 2.2.2 requires a second-degree or diploma-level qualification following “no less than two years’ full time or part time equivalent”, and — as written in that document — either a pass at Part 1 or a prescribed Part 1 qualification.

Note that ARB’s website currently says something different about that last requirement for 2026: that you “will not need to have an ARB-accredited Part 1 qualification or have passed the Part 1 Prescribed Exam to be eligible for the Part 2 Prescribed Exam”. The Procedures PDF and the website are not aligned on this point. Ask ARB which governs your application, and keep the answer.

Practical requirements. ARB requires IELTS 6.5 or above “in each of the band scores” if English is not your first or dual language, with an academic-level test. Applications go to ARB’s exams inbox. The fee is £1,950 per part. Incomplete or ineligible applications are returned with 25% of the fee retained as a scrutiny charge. After a first failure you are “allowed two further attempts only”; a fourth is at the Registrar’s discretion on evidence of material improvement.

Timing. ARB says exams are held virtually and that it is “currently running a waiting list of approximately three months on a first-come, first-served basis.” Note that the application deadline for the current examination has passed — see our separate piece on the 2026 status before you plan around this route.

Route 2 — A mutual recognition agreement (only if you are already registered)

ARB has registration-level agreements with a small set of regulators. Its International Routes pages list mutual recognition agreements with NCARB (United States), AACA and NZRAB (Australia and New Zealand) and ROAC (Canada), plus a memorandum of understanding with HKIA (Hong Kong).

Two things decide whether this is your route.

First, the partner body decides eligibility, not ARB. The UK Adaptation Assessment page says so in terms: “Contact your Mutual Recognition Agreement (MRA) partner organisation to check if your qualifications fall within the scope of the MRA. ARB cannot assess your eligibility.” You obtain a certificate from the partner, the partner sends it to ARB, and only then does ARB engage.

Second, an agreement covers registered architects, not graduates. ARB’s NCARB FAQ answers the common misreading directly: the agreement “accommodates only those who have fulfilled all of the requirements to qualify for NCARB certification and does not provide for the ‘freestanding’ recognition of a US professional degree in architecture.” A US professional degree on its own does not travel; a licensed US architect’s certification does.

The Australia/New Zealand agreement is drawn differently, and this matters if you studied there: ARB says the MRA “provides for the ‘freestanding’ recognition of AACA-accredited masters-level qualifications issued in Australia and New Zealand”, after which “Applicants will then be able to complete a UK Part 3 qualification to qualify for entry to the UK Register.” The Hong Kong MoU works similarly at qualification level: ARB states that “Hong Kong graduates with both HKIA-accredited bachelor’s and master’s qualifications will only need to complete an ARB-accredited Part 3 qualification to be eligible to join the UK Register.”

If you come in as a registered architect from the US, Australia, New Zealand or Canada, ARB requires the UK Adaptation Assessment before admission. Its arrangements and cost are covered separately; ARB has published that the UKAA “will continue to operate until October 2026” and is to be replaced by a Readiness for Practice in the UK module it expects to introduce in spring 2027.

Route 3 — Take an ARB-accredited UK qualification

The least discussed and often the most honest answer. Under ARB’s framework for UK qualifications you need, in its words, “an accredited master’s level qualification that encompasses the Academic Outcomes” together with “an accredited practice level qualification that encompasses the Practice Outcomes”, or a single combined accredited qualification covering both.

For someone holding an overseas architecture degree, ARB’s own guidance for mixed qualifications is explicit about where that leaves you. Where a person has “only a UK Part 2, a UK non-prescribed architecture undergraduate degree, and/or other international qualifications”, ARB says: “You will need to acquire a UK accredited practice level Qualification or outgoing Part 3.”

In plain terms: an accredited UK master’s plus the practice qualification gets you there without ever sitting the Prescribed Examination. It costs more and takes longer. It also removes the eligibility argument entirely, because the qualification is accredited by ARB rather than being argued as equivalent to one.

Whether a school will admit you onto an accredited master’s with your overseas degree is the school’s decision, made under its own admissions rules. ARB does not make it and neither do we.

The requirement none of the three removes

Practical experience and a practice-level assessment. ARB states that before sitting a Part 3 examination “you will be required to demonstrate a two year period of practical experience”, and its guidance for people with an outgoing Part 3 says applicants “are likely to be required to have undertaken 24 months of professional practical experience, of which 12 months must be undertaken in the UK, and directly in the two years before you apply for registration.”

That UK-based twelve months is the constraint most overseas applicants discover last and plan for least.

What to do with this

1. Answer the licence question first. Registered architect in the US, Australia, New Zealand or Canada? Start with your home regulator, not with ARB. Graduate only? Routes 1 and 3 are your set.
2. Check the Procedures PDF, not just the web page. Eligibility is written in ARB’s Examination Procedures. Where the PDF and the site diverge — and on Part 2 eligibility they currently do — get ARB’s position in writing.
3. Cost the whole path, not the first step. Every route ends in a UK practice-level qualification plus practical experience, twelve months of which must be in the UK.
4. Do not plan a visa around any of this here. Immigration permission is a separate matter decided by a different authority; ARB says of its own MRA applicants that they must “obtain and continue to have at all times lawful authorisation to work” and refers people to the UK government. So do we — check gov.uk.

We do not assess qualifications, do not decide eligibility, and cannot tell you which route ARB will accept for you. Those are ARB’s decisions under its own rules. What this page does is set out the three doors as ARB has published them, and name the requirement that sits behind all three.
