How to Become a Radiologic Technologist: Your Step-by-Step Career Guide
So you want to become a radiologic technologist — but where do you even start? Between choosing the right program, getting into clinicals, and passing the ARRT exam, the path can feel overwhelming. The good news? It's a well-trodden road, and thousands of successful rad techs have walked it before you.
This guide breaks the entire journey into six clear steps, from high school prerequisites to landing your first job. Whether you're fresh out of high school, changing careers, or just exploring the field, you'll find everything you need here.
What Is a Radiologic Technologist?
A radiologic technologist (also called a radiographer or rad tech) is a healthcare professional who performs diagnostic imaging examinations. imaging examinations. You're the person who positions patients, operates X-ray equipment, and ensures high-quality images for radiologists to interpret. Rad techs work in hospitals, outpatient clinics, urgent care centers, and imaging centers.
Your daily responsibilities include:
- Explaining procedures to patients and addressing their concerns
- Positioning patients accurately to obtain diagnostic images
- Selecting appropriate technical factors (kVp, mAs) for each examination
- Following strict radiation safety protocols to protect patients and yourself
- Documenting patient history and maintaining records
- Assisting radiologists with specialized procedures
It's a hands-on, patient-facing role that blends technical skill with compassionate care. If you enjoy anatomy, technology, and helping people, it's one of the most satisfying careers in healthcare.
Why Choose a Career in Radiography?
The demand for radiologic technologists continues to grow. Here's what makes this career path attractive:
| Factor | What It Means for You |
|---|---|
| Job Growth | 6% growth projected through 2033 (BLS), faster than average for all occupations |
| Entry Requirements | Associate degree (2 years) is the most common path — shorter than nursing or many allied health roles |
| Work Environment | Hospitals, clinics, urgent care, mobile imaging — variety of settings to choose from |
| Advancement | Cross-train into CT, MRI, mammography, nuclear medicine, or radiation therapy |
| Schedule Flexibility | Many facilities offer 3×12 shifts, weekends-only, or per-diem options |
| Patient Impact | Direct patient interaction — you make a difference in every patient's experience |
Radiography is also an excellent stepping stone into other imaging modalities. Many technologists start in X-ray and later cross-train into CT, MRI, or mammography — each bringing a higher salary and new challenges.
Step 1: Meet the Prerequisites
Before you can enroll in a radiography program, you'll need a high school diploma or GED. If you're still in high school, focus on these subjects:
- Biology and anatomy — foundational knowledge for understanding human structure
- Physics and math — radiation physics and exposure calculations require solid math skills
- Communication — you'll interact with patients, radiologists, and other healthcare staff daily
Some programs also require prerequisite college courses (e.g., English composition, college algebra, human anatomy and physiology with labs) before you can apply. Check with each program you're considering.
Step 2: Choose an Accredited Radiography Program
This is the most important decision you'll make. Your program must be accredited by the Joint Review Committee on Education in Radiologic Technology (JRCERT) — otherwise you won't be eligible to take the ARRT exam.
Three main program types are available:
| Program Type | Duration | Degree | Best For |
|---|---|---|---|
| Certificate Program | 21–24 months | Certificate | Career changers who already hold a degree in another field |
| Associate Degree (AS/AAS) | 24 months | Associate of Science | Most common path — offered at community colleges nationwide |
| Bachelor's Degree (BSRS) | 48 months | Bachelor of Science | Students seeking management, education, or advanced modality roles |
The associate degree is by far the most common entry path. It's efficient (2 years), affordable at community colleges, and fully prepares you for the ARRT exam. If you're considering management or teaching later, a bachelor's degree gives you an edge — but it's not required to start working.
Key factors when choosing a program:
- JRCERT accreditation — non-negotiable for ARRT eligibility
- ARRT exam pass rate — programs publish these; look for 90%+ first-time pass rates
- Clinical site variety — more sites = more diverse clinical experience
- Job placement rate — measures how many graduates find jobs within 6-12 months
Step 3: Complete Your Clinical Training
Classroom learning gets you the theory, but clinical rotations are where you become a real radiologic technologist. Clinical training typically starts in the first or second semester and runs throughout the program, with students spending 20-40 hours per week in affiliated hospitals and clinics.
During clinicals, you'll learn to apply positioning techniques from the most authoritative reference in the field: Clark's Pocket Handbook for Radiographers. Your instructors will expect you to master specific projections — for example, when positioning for an AP knee, Clark's specifies centering 2.5 cm below the apex of the patella (not at the patella itself, as many beginners assume). For the lateral knee, Clark's calls for 45° or 90° flexion — a detail that differs from some other references that suggest 20-30°.
You'll also learn to evaluate your own images — checking for proper positioning, collimation, exposure factors, and image markers. The ability to critique your own work is what separates a competent technologist from an excellent one. The Radiography 101 app includes evaluation criteria and common errors for all 87 projections, making it a handy study companion during clinical rotations.
Core Clinical Competencies
Most JRCERT-accredited programs require you to demonstrate competency in approximately 35-40 projections covering the:
- Chest and thorax — PA, lateral, AP, decubitus
- Upper extremity — hand, wrist, forearm, elbow, humerus, shoulder
- Lower extremity — foot, ankle, tib/fib, knee, femur, pelvis, hip
- Spine — cervical, thoracic, lumbar, sacrum/coccyx, SI joints
- Abdomen — KUB, acute abdomen, decubitus
- Head and facial bones — skull, sinuses, facial bones, mandible
Step 4: Pass the ARRT Certification Exam
After graduating from your JRCERT-accredited program, you're eligible to sit for the American Registry of Radiologic Technologists (ARRT) certification exam. This is your ticket to practice — you cannot work as a radiologic technologist without ARRT certification.
The exam covers four major content categories:
| Category | Weight | Key Topics |
|---|---|---|
| Patient Care | ~20% | Communication, safety, infection control, patient monitoring, pharmacology |
| Safety | ~25% | Radiation protection, ALARA, dose limits, shielding, pregnant patients |
| Image Production | ~25% | kVp, mAs, technique factors, image quality, digital receptors, processing |
| Procedures | ~30% | Positioning, anatomy, pathology recognition, modifications for trauma |
The exam has 200 multiple-choice questions, and you get 4 hours to complete it. It's computer-based and offered year-round at Pearson VUE testing centers. For detailed study strategies, check out our ARRT Exam Prep Guide.
Tips for ARRT Exam Success
- Start early — begin reviewing at least 8-12 weeks before your exam date
- Focus on procedures — it's the largest category (30%) and where positioning knowledge pays off
- Know your dose limits cold — radiation safety questions are high-yield (25% of the exam)
- Practice with ARRT-style questions — get comfortable with the format and time pressure
- Use the Radiography 101 app — practice 56 ARRT-style quiz questions with Clark's-verified answers right on your phone
Step 5: Get Licensed in Your State
ARRT certification is not the same as state licensure. Most states require radiologic technologists to hold a state license in addition to ARRT certification. Some states have their own exam, while others accept ARRT results. A few states (like California and Texas) have additional requirements, including a state-specific jurisprudence exam.
Check with your state's Department of Health or Radiologic Technology Board for specific requirements. The ARRT website also maintains a state-by-state licensure map.
Step 6: Start Your Career — and Keep Growing
Once you've passed the ARRT exam and secured your state license, you're ready to work. Most new graduates start in hospital settings, where they gain exposure to a wide range of examinations — from emergency department portables to routine outpatient X-rays.
But radiography is just the beginning. Many technologists go on to specialize:
| Specialty | Additional Certification | Average Salary Boost |
|---|---|---|
| Computed Tomography (CT) | ARRT (CT) | +$5,000–$10,000 |
| Magnetic Resonance Imaging (MRI) | ARRT (MR) | +$8,000–$15,000 |
| Mammography | ARRT (M) | +$3,000–$8,000 |
| Nuclear Medicine | ARRT (N) or NMTCB | +$10,000–$15,000 |
| Radiation Therapy | ARRT (T) | +$10,000–$20,000 |
Cross-training into CT or MRI is a common path after 1-2 years of general radiography experience. Many employers offer tuition reimbursement for advanced certifications — it's worth asking about during your job interview. For more on choosing between modalities, see our CT vs MRI comparison guide.
How Long Does It Take?
Here's a realistic timeline from start to first job:
| Stage | Time | Notes |
|---|---|---|
| Prerequisites (if needed) | 0–12 months | Depends on prior education; some programs include these |
| Radiography program | 21–48 months | Certificate (21-24mo), Associate (24mo), Bachelor's (48mo) |
| ARRT exam preparation | 1–3 months | Overlap with final semester |
| State licensure | 1–3 months | Processing time varies by state |
| Job search | 1–6 months | Strong job market but varies by location |
| Total (associate degree path) | ~2–3 years | From high school graduation to first job |
The associate degree path from a community college is the fastest and most affordable route. You can go from high school graduation to working as a rad tech in about two and a half years.

Common Questions About Becoming a Rad Tech
Do I need a bachelor's degree?
No. An associate degree from a JRCERT-accredited program is sufficient for ARRT certification and entry-level employment. A bachelor's degree is helpful if you plan to move into management, education, or advanced practice later.
Is radiography hard to study?
It's rigorous but manageable. The most challenging topics for most students are radiation physics and anatomy. The clinical component is physically demanding — you'll be on your feet, moving patients, and working in a fast-paced environment. But students who stay organized and study consistently do well.
Can I work while studying?
Many students work part-time, but be realistic about your schedule. Clinical rotations (20-40 hours/week) plus classroom time and studying can be draining. Some programs discourage outside work during the first semester.
Are online radiography programs legitimate?
Only if they're JRCERT-accredited and include in-person clinical rotations. Pure online programs without clinical components are not ARRT-eligible. Look for hybrid programs that combine online didactic instruction with hands-on clinical training at affiliated sites.
