Understanding how to take the ARRT exam is the first critical step toward launching your career as a credentialed radiologic technologist. The American Registry of Radiologic Technologists certification is the gold standard in the field, recognized by employers across all 50 states and required for licensure in most jurisdictions. Whether you are preparing for your initial certification in Radiography, Computed Tomography, or another discipline, navigating the application process, eligibility requirements, scheduling logistics, and exam-day protocols can feel overwhelming without a clear roadmap to follow.

The ARRT certification exam is a computer-based test administered through Prometric testing centers nationwide. Candidates must first establish eligibility by meeting both education and ethics requirements before they can even submit an application. The education requirement involves completing an accredited program recognized by the ARRT, while the ethics component requires candidates to disclose any prior criminal history or disciplinary actions for review. Both pathways take time, so beginning this process several months before your anticipated graduation date is strongly recommended to avoid delays in starting your career.

Once your application is approved, ARRT issues an Authorization to Test (ATT) letter, which is your official permission to schedule your exam at a Prometric location. The ATT remains valid for a 90-day testing window, during which you must sit for the exam. Missing this window requires reapplication and additional fees, so candidates should plan their study schedule carefully to ensure they are fully prepared before the window opens. Many candidates make the mistake of scheduling too early before completing sufficient preparation, so build your study timeline around the ATT receipt rather than around graduation.

The ARRT Radiography exam consists of 220 questions total, though only 200 of those are scored — the remaining 20 are unscored pilot questions used to validate future exams. You will have three hours to complete the examination. The content spans five major categories: Radiation Protection, Equipment Operation and Quality Control, Image Production, Procedures, and Patient Care and Education. Each category carries a specific percentage weight in the final score, and understanding these weights helps you prioritize your study time most effectively during your preparation period.

Passing the ARRT exam requires a scaled score of at least 75 on a scale that converts your raw performance into a score ranging from 1 to 99. It is important to understand that 75 does not mean answering 75 percent of questions correctly — the scaled scoring system accounts for question difficulty and exam version variation. First-time pass rates for the Radiography primary pathway hover around 90 percent for candidates who graduate from accredited programs, which reflects both the rigor of those programs and the importance of structured exam preparation during the months leading up to test day.

Candidates who do not pass on their first attempt are permitted to retake the ARRT exam, but there are limits. You may attempt the examination up to three times within a calendar year, with a mandatory 90-day waiting period between each attempt. After three unsuccessful attempts within a year, you must wait until the following calendar year to try again. Repeated failures also trigger additional ethics and competency review by ARRT, so it is always better to invest heavily in preparation before your first attempt rather than relying on retake opportunities as a safety net.

This comprehensive guide walks you through every stage of the process — from verifying your eligibility and submitting your application, to selecting the right study materials, scheduling your Prometric appointment, and walking into the testing center on exam day with full confidence. We also explore maintenance of certification requirements, since earning your credential is just the beginning of an ongoing commitment to professional development. For specifics on post-certification continuing education obligations, our guide on how to take arrt exam requirements for renewal provides detailed guidance.

The ARRT application process begins well before you sit down at a Prometric computer, and understanding each stage helps you avoid costly delays. Your first step is to verify that your radiologic technology program holds accreditation from either the Joint Review Committee on Education in Radiologic Technology (JRCERT) or another ARRT-recognized accreditor. Graduates of non-accredited programs are not eligible for the primary eligibility pathway and must pursue an alternate route, which involves additional documentation and a longer review timeline that can push your credentialing back by six months or more.

The ethics review is often the most anxiety-inducing part of the application for many candidates, but it need not be. ARRT requires full disclosure of any misdemeanor or felony convictions, military court-martial offenses, and certain disciplinary actions taken by healthcare or educational institutions. Failure to disclose is considered a violation of the ARRT Standards of Ethics and can result in permanent denial of certification — far worse than the outcome of an honest disclosure. Most minor, old offenses result in approval after review, so honesty is always the correct strategy when completing the ethics documentation.

Once you submit your application online through the ARRT website, the typical processing time is four to six weeks for straightforward cases. During this period, ARRT verifies your program completion, reviews your ethics disclosure, and confirms you meet the structured education competency requirements. Your program director plays a key role here, as ARRT will contact them to verify that you completed all required clinical competencies. Staying in regular contact with your program director and making sure your competency documentation is complete before you apply significantly reduces the risk of processing delays.

After ARRT approves your application, you will receive your Authorization to Test (ATT) via email. This document contains your candidate identification number and instructions for scheduling at Prometric. Read this email carefully and save it — you will need the candidate ID number when booking your appointment. The 90-day testing window begins on the date listed in your ATT, not the date you receive the email, so act promptly. Log into the Prometric website within the first week of receiving your ATT to book a date that gives you two to four weeks of additional focused preparation time.

When scheduling your Prometric appointment, choose a test center location that is convenient and familiar. Visit the testing center location in advance if possible — knowing the parking situation, the check-in desk location, and the general environment reduces day-of stress considerably. Prometric allows you to reschedule appointments up to 30 days before your scheduled date at no charge, and later rescheduling incurs fees. If you must reschedule within five business days of your exam, you forfeit the exam fee entirely, so avoid last-minute changes by committing to a date only when you are genuinely ready.

The ARRT application fee for the Radiography primary pathway is currently $200, with additional fees for specialty certifications and post-primary pathways. Candidates who need to reschedule within the late window or who miss their appointment without prior cancellation lose their fee and must reapply, paying the full application cost again. Budgeting for these costs upfront — and treating exam day as a hard commitment once scheduled — prevents unnecessary financial setbacks during an already stressful time in your professional development.

Candidates pursuing post-primary specialty certifications such as CT, MRI, Mammography, or Interventional Radiology face slightly different eligibility requirements. These pathways require you to hold a current primary ARRT certification in an appropriate discipline and to document clinical experience hours and competencies specific to the specialty. The application process mirrors the primary pathway in most respects, but the content specifications for each specialty exam differ significantly, requiring a tailored study approach for each credential you pursue.

When exam day finally arrives, what happens at the Prometric testing center often surprises first-time candidates who have not prepared for the procedural aspects of computer-based testing. Arrive at the test center at least 30 minutes before your scheduled appointment time. Prometric check-in procedures are thorough and involve identity verification, biometric data collection, and a security inspection — arriving late can result in being turned away and forfeiting your exam fee. The center will provide you with a locker for all personal belongings, since nothing is permitted in the testing room except the provided materials.

The check-in process includes presenting your government-issued photo ID with a name that exactly matches the name on your ATT letter. Discrepancies — even minor ones like a middle initial appearing in one document but not the other — can prevent you from testing. If your legal name has changed recently due to marriage or other circumstances, update your ARRT account and contact Prometric before your appointment to ensure both documents align. The testing staff will also photograph you and may take a palm vein scan as an additional biometric security measure.

Once seated at your assigned computer terminal, you will complete a brief tutorial on the testing interface before your exam begins. This tutorial time does not count against your three-hour exam time limit, so use it fully to familiarize yourself with the marking and review features.

The ARRT exam interface allows you to flag questions for review, navigate forward and backward freely, and revisit marked questions before submitting. Many high-scorers recommend answering every question on the first pass — even if unsure — flagging the uncertain ones, and then returning for a focused second review rather than leaving blank answers during the initial pass-through.

During the exam itself, time management is essential but the three-hour limit is generally sufficient for most candidates who have prepared adequately. At roughly one minute per question for 200 scored questions, you have about 40 minutes of buffer time for review, restroom breaks, or extended deliberation on complex questions. Prometric offers scheduled breaks, but each break counts against your overall testing time, so plan strategically. Many candidates take a single five-minute break at the halfway point to reset mentally before completing the second half of the examination.

Question types on the ARRT exam are primarily multiple choice with four answer options, but some questions present clinical scenarios where you must apply knowledge to a described patient situation rather than simply recalling a fact.

These scenario-based questions tend to be the most challenging because they require integration of multiple content areas — for example, a question might describe a trauma patient and ask you to identify both the optimal positioning modification and the appropriate technical factor adjustment needed to produce a diagnostic image. Practice with scenario-based questions during your preparation period is the most direct way to build this integrative thinking skill.

ARRT exam results are available immediately upon completion of the exam at the testing center. The Prometric software calculates your scaled score and displays whether you passed or failed before you leave the building. Seeing your result on screen — pass or fail — immediately after submitting your final answer can be an intensely emotional experience, so prepare yourself mentally for both outcomes. If you pass, your official ARRT credential documentation arrives within approximately two weeks and your certification status becomes verifiable in the ARRT online registry almost immediately.

Candidates who do not pass receive a diagnostic performance report along with their score report, which breaks down their performance by content category. This report is an invaluable resource for retake preparation because it identifies specific areas of weakness with statistical precision. If you score below average in Procedures but above average in Radiation Protection, your retake study plan should dedicate the majority of time to Procedures review while using less intensive maintenance study for the stronger areas. Never attempt a retake without thoroughly analyzing this diagnostic report and building a targeted study plan based on what it reveals.

Earning your ARRT certification is not the end of the credentialing journey — it is the beginning of a two-year renewal cycle that requires ongoing professional development. The ARRT Continuing Qualifications Requirements (CQR) program mandates that all registered technologists complete 24 continuing education (CE) credits during each two-year renewal period. These CE credits must be earned through ARRT-recognized providers, and at least half must be category A credits, which are produced by accredited organizations. The specific topics you are required to study may also include structured self-assessment components depending on your certification discipline and renewal cycle year.

CE credits can be earned through a wide variety of formats, including online courses, in-person seminars, journal reading programs, webinars, and professional conference attendance. The ARRT's online CE tracking system, called My ARRT, allows you to log completed activities, verify recognized providers before enrolling in a course, and monitor your progress toward the renewal requirement throughout the two-year cycle. Keeping your CE tracking current throughout the cycle — rather than scrambling to complete 24 credits in the final months — reduces stress and ensures you have time to select high-quality, content-relevant learning activities rather than quick-completion options.

The two-year renewal fee for ARRT certification is currently $60 for most primary disciplines. Payment is due before your certification expiration date, and late payments incur additional fees. If your certification lapses — which happens when the renewal deadline passes without completing CE requirements and paying the renewal fee — reinstatement requires additional steps, fees, and potentially a demonstration of current competency. Treating your renewal deadline with the same seriousness as your original exam deadline protects the credential you worked hard to earn and maintains your ability to practice legally in licensed states.

Many experienced technologists use their CE credits strategically to support career advancement goals rather than simply satisfying the minimum requirement. For example, if you plan to pursue a CT specialty certification within the next two years, completing CE coursework in cross-sectional anatomy and CT physics serves double duty: it satisfies renewal credits while simultaneously building the knowledge base you need for the specialty exam. This approach maximizes the return on your continuing education investment and keeps your professional development aligned with your career trajectory rather than treating CE as a checkbox exercise.

ARRT also administers a program called Structured Self-Assessment (SSA), which is required for most primary discipline certifications during alternating renewal cycles. SSA is a self-directed learning activity that requires you to answer a set of content-specific questions, identify areas where your knowledge needs refreshing, and complete targeted educational activities to address those gaps. The SSA process is completed through the My ARRT portal and counts toward your CE credit requirement, making it an integrated component of the renewal cycle rather than an additional burden on top of standard CE requirements.

Technologists who hold multiple ARRT certifications — for example, primary Radiography plus specialty certifications in CT and Mammography — must maintain each credential separately, though the CE credits earned typically apply toward renewal of all held certifications simultaneously. Managing multiple credential renewal cycles requires careful calendar tracking to ensure no single certification lapses while you are focused on another. Many technologists set annual calendar reminders 12 months and 6 months before each renewal deadline to stay ahead of requirements and avoid last-minute scrambles that can lead to costly errors.

For a detailed breakdown of exactly how many CE credits are required for your specific certification and discipline, including which topics qualify as category A credits and which providers are currently recognized, reviewing the dedicated continuing education requirements guide is the most reliable approach. Understanding ongoing requirements from the start helps you plan a sustainable professional development calendar that keeps you credentialed, current, and competitive throughout a long and rewarding career in radiologic technology.

Effective study planning for the ARRT exam requires treating preparation as a structured project rather than an open-ended review. Most candidates benefit from a 10 to 14 week study timeline that begins immediately after clinical rotations conclude.

Start by downloading the official ARRT content specifications document, which is available free on the ARRT website and lists every testable topic organized by category and subcategory. This document is your master curriculum — any topic on it is fair game for the exam, and any topic not on it is almost certainly not worth studying in depth regardless of how much it came up in your program coursework.

Divide your study timeline into three phases. In the first phase, lasting approximately four weeks, focus on comprehensive content review using a primary study resource such as Lange Q&A Radiography Examination or Mosby's Comprehensive Review of Radiography. Read each chapter systematically and take notes on high-yield facts, formulas, and positioning criteria.

During this phase, resist the urge to jump into practice questions before you have a foundational understanding of each content area — answering questions before building content knowledge leads to pattern memorization rather than genuine conceptual understanding, which breaks down on the exam when questions are phrased differently than expected.

In the second phase, spanning weeks five through nine, shift your focus to active practice testing with full content integration. Complete 50 to 100 practice questions per day, mixing content areas rather than studying one category at a time.

After each practice session, review every incorrect answer in detail — not just the right answer, but why your chosen answer was wrong and what reasoning error led you to select it. This error-analysis habit is the single highest-leverage study behavior that separates candidates who pass on the first attempt from those who struggle through multiple retakes despite putting in comparable total hours of study time.

The third phase, covering the final two weeks before your exam, should be dedicated to timed full-length practice exams and light review rather than introduction of new material. Take at least two complete 200-question timed practice exams under realistic conditions: same time of day as your scheduled exam, minimal breaks, and no looking up answers mid-exam.

These simulations train your stamina, time management, and test-taking composure in ways that shorter practice sessions cannot replicate. After each full-length simulation, score your results by category and compare them to the actual ARRT exam weighting to identify any remaining weak spots that need targeted attention.

Physical preparation in the days immediately before your exam matters more than many candidates expect. Avoid the temptation to cram new material in the final 48 hours — at this point, additional content review yields minimal benefit and increases anxiety significantly.

Instead, do light review of your highest-confidence material, maintain normal sleep patterns, and prepare everything you need for test day the night before: your photo ID, directions to the Prometric center with an alternative route planned, and an alarm set for a time that allows a relaxed morning without rushing. Arriving at the test center calm, rested, and confident is worth more than any last-minute studying.

Nutrition and hydration on exam day are practical factors that many candidates overlook entirely. The ARRT exam is a three-hour cognitive endurance test, and your brain performs meaningfully better when well-fueled. Eat a balanced meal containing protein and complex carbohydrates before your exam rather than a light snack or nothing at all.

Caffeine is fine if you use it regularly, but avoid consuming significantly more than your normal amount on exam day, as excessive caffeine increases anxiety and can disrupt focus during the extended sitting. Bring water to the Prometric center if permitted — staying hydrated during a three-hour exam supports concentration and mental clarity throughout.

Mental approach during the exam itself is a skill that is often undervalued but can meaningfully affect your score. When you encounter a question you find genuinely difficult, use a systematic elimination strategy: identify and eliminate any answer choices that are clearly incorrect, then apply your deepest content knowledge to the remaining options.

In many cases, two of the four options can be eliminated quickly, turning a true guess into a 50/50 decision with much better odds. Trust your preparation, commit to an answer rather than second-guessing indefinitely, and move forward. Lingering too long on individual questions creates time pressure later in the exam that compounds anxiety and impairs decision-making on questions you would otherwise answer correctly.
