ARRT Limited Scope Radiography Exam Guide 2026

ARRT Limited Scope of Practice in Radiography Exam Guide 2026

The ARRT Limited Scope of Practice in Radiography exam is different from many healthcare exams because it is modular. You do not simply take one national credentialing exam with the same procedure content as every other candidate. ARRT administers the exam on behalf of state licensing agencies, and your state determines which modules you need for the limited license or permit you are pursuing.

That means your first study task is not buying a random question bank. It is confirming your state-approved modules, then mastering the Core module before adding the procedure modules that apply to your license.

Official Sources and 2026 Status

ARRT hosts the current content specifications on its Examination Content Specifications page and publishes the state licensing handbook as the Limited Scope Examination Handbook PDF.

ARRT also published a 2026 notice seeking comments on proposed Limited Scope content changes, with a scheduled implementation date of January 1, 2028. That matters for 2026 candidates: unless ARRT or your state agency tells you otherwise, study from the current handbook and current content specifications, not from draft 2028 changes.

Exam Structure: Core Plus State-Required Procedure Modules

The Limited Scope exam is delivered in modules. ARRT lists the modules as Core, Chest, Extremities, Skull/Sinuses, Spine, and Podiatric. All candidates take Core and then one or more procedure modules depending on state license requirements.

Because procedure modules add both time and questions, your total exam length depends on what your state requires. Do not assume another candidate's module list applies to you.

What the Core Module Really Tests

Patient Care: fewer questions, high consequence

Patient Care is 18 scored Core questions, but it is risky because candidates often underprepare it. Focus on patient rights, informed consent, confidentiality, patient identification, communication barriers, infection control, vital signs, medical emergencies, and legal scope.

A limited operator must know when to proceed, when to clarify an order, when to stop, and when to get help. Many patient care questions are judgment questions dressed as basic facts.

Safety: the largest Core category

Safety has 40 scored Core questions. You need more than ALARA as a slogan. Know radiation physics, x-ray production, biological effects, dose units, time-distance-shielding, beam restriction, exposure factors, personnel monitoring, pregnancy considerations, shielding, and patient protection.

The handbook notes that SI units became the primary radiation measurement units for the exam in 2018, so practice with mGy, mSv, and related SI language.

Image Production: technical troubleshooting

Image Production has 42 scored Core questions, the largest Core content count. This is where candidates who only memorize positioning struggle. Be ready to troubleshoot exposure indicators, quantum noise, contrast, spatial resolution, distortion, artifacts, markers, radiation fog, detector maintenance, display monitor QA, beam alignment, and equipment malfunction reporting.

Procedure Module Strategy

Procedure modules test positions and projections for the anatomy your state authorizes. Your job is to know the required projections, central ray, patient position, anatomy demonstrated, evaluation criteria, and when a projection is not appropriate.

If your state requires only Core plus one procedure module, do not spend equal time on every possible module. Spend enough time on non-required modules to understand shared terminology, but put your scored time where your authorization actually sits.

5-Week Study Plan

Common Mistakes

1. Studying the wrong modules. Your state decides which modules matter. Confirm before you build your plan.
2. Treating Limited Scope as easier Radiography. It is narrower in scope, but ARRT says limited operators should possess the same knowledge and cognitive skill in their specific area as radiographers.
3. Skipping Core because procedure positioning feels more concrete. Core is required for all candidates and includes the largest question counts.
4. Ignoring pilot questions. Core includes 15 unscored pilot questions and each procedure module includes 5. They are not identified, so manage time evenly.
5. Memorizing projections without image evaluation. Procedure questions can ask whether an image is acceptable, what anatomy is demonstrated, or what positioning error occurred.
6. Using draft 2028 content as current content. ARRT's 2026 proposed changes have a scheduled January 1, 2028 implementation date, so 2026 candidates should verify current documents.

Exam-Day Reminders

• Bring the identification required by your ARRT/Pearson VUE authorization and state instructions.
• Take the tutorial seriously if you have not used the testing interface before.
• Track module time separately. A hard procedure item should not steal time from the rest of the module.
• For image quality questions, identify whether the issue is exposure, contrast, spatial resolution, distortion, marker placement, artifact, or positioning.
• For safety questions, start with patient and personnel protection principles, then apply the scenario details.
