ARRT Radiography Certification Exam

The American Registry of Radiologic Technologists (ARRT) Radiography exam is the credentialing exam behind the R.T.(R) post-nominal, and most US states build their licence around it. It is delivered by computer at Pearson VUE test centres.

Content categories & weightings (200 scored items)

Updated content specifications have been board-approved to take effect for exams from January 2027 — if you’re testing in 2027 or later, download the new spec from ARRT before building your study plan.

Eligibility

• Education: associate degree or higher plus completion of an ARRT-recognised radiography programme (typically JRCERT-accredited).
• Didactic & clinical competency requirements signed off by your programme director.
• Ethics: good-moral-character review; disclose any criminal or regulatory history (pre-application ethics review is available).

Scoring, retakes & the 3-in-3 rule

• Scores are scaled to adjust for form difficulty; 75 is the pass mark regardless of which form you sit.
• You get a maximum of three attempts within three years of your first exam window. Fail three times (or run out the three years) and your eligibility ends — you must then requalify (usually further education) before applying again.
• A re-application fee applies to each retake.

Prep strategy

• Weight your revision like the exam: Procedures (33%) + Image Production (25.5%) is nearly 60% of your marks — positioning criteria, technique adjustments, exposure factors and artifact recognition are the highest-yield material.
• Safety is the most predictable category: dose limits, ALARA, inverse square law, beam filtration, grid/collimation effects and pregnancy protocols come up in stable, learnable patterns.
• Timeline: most candidates do well with 8–12 weeks of structured review after graduation — 2–3 timed mocks in the final fortnight, reviewing every wrong answer against the content specification line it maps to.
• Sit the exam soon after your programme ends; first-time pass rates are highest within a few months of graduation.

HCPC Registration — No National Exam

The UK is different: there is no board exam. “Radiographer” is a protected title regulated by the Health and Care Professions Council (HCPC). You qualify by completing an HCPC-approved degree (usually a 3-year BSc (Hons) Diagnostic Radiography, or a pre-registration MSc) — the assessment happens inside the programme, not after it.

What assessment looks like instead

• Academic: written exams, OSCE-style image-appraisal and positioning stations, physics and dosimetry assessments, and a research project — every module must be passed to a standard mapped to the HCPC Standards of Proficiency.
• Clinical: roughly a third to a half of the programme is placement. You build a competency portfolio signed off by practice educators covering general, mobile, theatre, trauma and paediatric imaging.
• On graduating from an approved programme you apply straight onto the HCPC Register — a paperwork scrutiny, not a test.

Preceptorship — your real “final exam”

Most NHS trusts run a structured preceptorship year for band 5 starters: a named preceptor, protected development time, regular reviews and sign-off of local competencies (CT head out-of-hours, theatre II, trauma). The Society of Radiographers (SoR) and NHS England both publish preceptorship frameworks — ask about them at interview; a good preceptorship programme is worth more than a higher starting banding.

Staying registered

• Renew every two years; keep a CPD record — HCPC randomly audits 2.5% of the profession each renewal cycle.
• International applicants (trained outside the UK) go through the HCPC international route instead: a one-off scrutiny fee of £678.38 and an individual assessment of your qualification and experience against the Standards of Proficiency.
• Note: an HCPC fee consultation is running in 2026 — check current amounts before you apply.

Prep strategy (for students)

• Treat every placement like an assessment: image-appraisal vocabulary (10-point checks, adequacy, repeat justification) is what OSCEs and vivas reward.
• Master IR(ME)R 2017 operator/practitioner duties and pregnancy checks — they appear in every UK academic assessment and every job interview.
• Join SoR as a student for indemnity, the Radiography journal and preceptorship resources.

MRPBA Registration & the National MRP Exam

Radiographers in Australia register with the Medical Radiation Practice Board of Australia (MRPBA) through Ahpra. Australian graduates of Board-approved programmes register directly — no exam. The National MRP Exam applies mainly to internationally qualified practitioners (after an ASMIRT skills assessment), returners after a long break, or where the Board has safety concerns.

The route for internationally qualified radiographers

1. ASMIRT skills assessment — the Australian Society of Medical Imaging and Radiation Therapy assesses your qualification and experience (indicative 2026 fees: from around AU$278 for pre-approved qualifications such as NZ, up to roughly AU$883 for a standard offshore assessment; allow 8–16 weeks — confirm current fees with ASMIRT).
2. National MRP Exam — computer-based, online-proctored via the Board’s examination portal (Webassessor). Based on the Professional capabilities for medical radiation practice; a practice test is available once your exam account is activated.
3. Ahpra registration — general registration with the MRPBA; the annual registration fee is AU$221 (2025/26), plus criminal history, English language (e.g. IELTS 7.0) and recency-of-practice standards.

Exam content

• Part A (common): professionalism, ethics and legal practice, safety and quality, communication and collaboration, evidence-based practice and radiation safety principles shared across the three divisions.
• Part B (diagnostic radiography): projection radiography technique and positioning, image evaluation, CT fundamentals, fluoroscopy, mobile/theatre work, dose optimisation and pathology recognition.
• The Board publishes an official reading and resources list — build your revision around it, it is effectively the syllabus.

Prep strategy

• Read the Professional capabilities document line by line — questions are written against it, including the “soft” domains (consent, cultural safety, Aboriginal and Torres Strait Islander health) that overseas candidates most often underestimate.
• Sit the built-in practice exam early to calibrate the question style, then plan 6–10 weeks of study around the reading list.
• With only three lifetime attempts, don’t book a window until your mocks are comfortably above 70% in both parts. From 30 March 2026 the updated Professional Capabilities also expect current BLS and anaphylaxis-response training — have certificates ready.

MRTB Registration (Medical Imaging Technologist)

Registration is with Te Poari Ringa Hangarau Iraruke — the Medical Radiation Technologists Board (MRTB) — under the Health Practitioners Competence Assurance Act 2003. Graduates of approved NZ programmes (e.g. BHSc Medical Imaging) register directly in the Medical Imaging Technologist (MIT) scope — no exit exam. Internationally qualified applicants are assessed for equivalence, and only sit the Board’s online exam if offered it as a pathway.

The overseas route

1. Apply online with certified qualifications, registration history from every regulator you’ve held, and criminal record checks for every country lived in >12 months since age 16.
2. The Registration Committee assesses whether your qualification and experience are equivalent to the NZ standard for the MIT scope. Australian registrants can use the faster TTMRA (Trans-Tasman Mutual Recognition) route instead.
3. If deemed not equivalent, you may be offered the online examination as a registration pathway: remotely proctored (Kryterion), run four times a year, with a practice exam available once enrolled. You pay the exam fee for every sitting, and two forms of ID (one government photo ID) are required on the day.
4. Once registered you need an Annual Practising Certificate (APC), renewed each year with CPD compliance.

Costs

The Board publishes a prescribed fee schedule (application, registration, examination and APC fees) on its website — fees are set by Gazette notice and updated periodically, so take the current amounts from the MRTB resources page rather than any third-party summary. Budget separately for criminal record checks, certified translations and (if needed) an English test such as IELTS.

Prep strategy

• If offered the exam, study to the NZ curriculum: projection radiography, CT, image evaluation, radiation safety under the NZ Radiation Safety Act 2016, and professional/ethical practice including the Code of Health and Disability Services Consumers’ Rights and cultural safety (Te Tiriti o Waitangi obligations feature in NZ professional standards).
• Use the built-in practice exam to learn the interface, and schedule your sitting 8:30am–1pm NZ time as the Board recommends, so technical support is available.
• Since a fresh fee (and agreement) applies to every resit, treat the first attempt as the only one: 6–8 weeks of structured review is realistic for a practising radiographer.

CAMRT Certification Exam — Radiological Technology

The Canadian Association of Medical Radiation Technologists (CAMRT) runs the national entry-to-practice certification exam in Radiological Technology; passing earns the RTR designation, which the provincial regulators (e.g. CMRITO in Ontario) require for licensure. It is a competency-based exam built on the National Competency Profile for Entry-Level MRTs.

Format & content

• Multiple-choice, computer-delivered in a single sitting, written remotely (online proctored) or at a test centre.
• Questions are written against the published exam blueprint, which maps every item to the National Competency Profile — expect applied, scenario-style questions (“what do you do next?”) rather than pure recall, across patient management, radiation safety, equipment operation, image production and procedures.
• Results are reported pass/fail on a scaled basis; check the current CAMRT exam preparation guide for the item count and timing of your sitting.

Eligibility & retakes

• Canadian graduates: completion of an accredited (EQual/Accreditation Canada) radiological technology programme.
• Internationally educated MRTs: a prior credential assessment through CAMRT’s IEMRT process (with language fluency requirements and optional bridging programmes) before exam eligibility.
• Retakes: a limited number of rewrites is permitted with re-registration and full fees each time — see CAMRT’s “Rewriting the Exam” policy. Registration deadlines are hard cutoffs with no exceptions.

Prep strategy

• Download the blueprint and competency profile first, and tick competencies off as you cover them — this is genuinely how the paper is assembled.
• Use CAMRT’s own practice exams and “how to write a competency-based exam” guide; the question style (best-next-action) trips up more candidates than the content does.
• Plan 10–12 weeks; IEMRTs should add the CAMRT Canadian Practice in Medical Radiation Technology module, since Canadian scope, consent and safety-culture questions are heavily represented.

CORU Registration — Radiographers Registration Board

In Ireland, “radiographer” is a protected title regulated by CORU (the Health and Social Care Professionals Council) through its Radiographers Registration Board. As in the UK, there is no national board exam: graduates of CORU-approved Irish programmes (e.g. the BSc Radiography at UCD) apply directly to the register.

Internationally qualified radiographers

1. Recognition of qualification: apply to CORU for recognition against the Irish standards of proficiency and education criteria (aligned with EU Directive 2005/36/EC mechanics). A recognition fee applies — check CORU’s current recognition fee page for the amount, which has changed in recent years.
2. Compensation measures: if the assessors find shortfalls, you may be offered a choice of an adaptation period (supervised practice) or an aptitude test — this is the closest thing Ireland has to a registration exam, and it is individually tailored to your identified gaps.
3. Registration: once recognised, apply to the register (€100), providing vetting (Garda/police clearance) and evidence of English competence where required, then pay the €100 annual retention fee thereafter.

What Irish assessment looks like in-programme

• Approved programmes assess through written and practical exams, clinical competency portfolios and research work mapped to CORU’s Standards of Proficiency for Radiographers.
• Newly qualified staff typically enter structured induction/preceptorship in their first HSE or voluntary-hospital post, and CPD is a statutory expectation under CORU’s continuing professional development requirements.

Prep strategy

• International applicants: front-load your paperwork — transcripts with clinical hour breakdowns per modality are the most common cause of delay. Ask your university for a detailed syllabus early.
• If offered an aptitude test, CORU tells you the exact subjects it covers; revise only those, using Irish/EU framing (EU BSS Directive 2013/59/Euratom and Irish S.I. No. 256/2018 for justification and dose).
• Timelines of 6–12 months for recognition are common — start before you plan to move.
