Most radiology tech programs take about two years to complete, though your total timeline from start to finish depends on the degree path you choose and whether you need prerequisite courses. An associate’s degree is the most common route, typically running 22 to 24 months of full-time study. Factor in prerequisites and certification, and many students spend closer to three years from their first college course to their first day on the job.
Associate’s Degree: The Most Common Path
The associate’s degree in radiologic technology is the standard entry point into the profession. These programs typically require 64 to 78 credit hours and take about 22 months of consecutive, full-time coursework. At the Community College of Denver, for example, the program runs five back-to-back semesters. Most community colleges follow a similar structure, blending classroom instruction with hands-on clinical rotations at hospitals or imaging centers.
What catches many students off guard is the prerequisite coursework required before they can even start the program itself. At Dalton State College, applicants need 10 prerequisite courses (32 credit hours) completed with at least a C grade before their cohort begins. These include anatomy and physiology I and II, college algebra, English composition, psychology, and speech. If you’re starting from scratch, knocking out these prerequisites typically adds two to three semesters to your timeline. That means the realistic total for many students is closer to three years from enrollment to graduation.
Programs are also competitive. Many schools admit students in cohorts once or twice a year, so if you miss an application deadline or don’t have your prerequisites finished in time, you could wait an additional semester before starting.
Bachelor’s Degree Programs
A bachelor’s degree in radiologic technology takes four years of academic coursework, and some programs add clinical training on top of that. At Stony Brook Medicine, the total length of study is five years: four years for the health science major plus a 12-month clinical certificate program. You need both components to qualify for the national certification exam.
A bachelor’s degree isn’t required to work as a radiology tech, but it can open doors to supervisory roles, education positions, or specialized imaging fields. Some students complete an associate’s degree first, start working, and then finish a bachelor’s through a bridge or completion program while employed.
Evening and Weekend Tracks
A few schools offer evening and weekend options for students who can’t attend during the day. Cuyahoga Community College, for instance, runs an evening/weekend track that admits students once a year in the fall semester. The total credit hours are the same as the daytime program (64 credits), and the school is upfront that the time commitment still requires the equivalent of a full-time schedule. These tracks give you more flexibility in when you’re in class or at clinical sites, but they don’t necessarily shorten or lengthen the overall program. True part-time radiology programs are rare because clinical rotations require consistent, sustained availability.
What Clinical Training Looks Like
Clinical rotations make up a large portion of any radiology tech program. You’ll spend time in hospitals and outpatient imaging centers learning to position patients, operate X-ray equipment, and produce diagnostic images under the supervision of licensed technologists. The national accrediting body for these programs, the JRCERT, doesn’t set a specific minimum number of clinical hours. Instead, programs must use a competency-based system, meaning you progress by demonstrating you can perform procedures correctly rather than simply logging a set number of hours. Clinical days are capped at 10 hours.
Most programs schedule clinical rotations alongside coursework starting in the first or second semester, so you’re applying what you learn almost immediately. By the end of the program, you’ll have experience with a range of imaging exams across different patient populations.
Certification After Graduation
Finishing your program isn’t the final step. To work as a registered radiologic technologist, you need to pass the national certification exam administered by the American Registry of Radiologic Technologists (ARRT). You can apply about three months before graduation, and most graduates take the exam shortly after completing their program. The exam is computer-based and results come relatively quickly, so many new grads are credentialed and job-hunting within a few weeks of finishing school.
Most states also require a license to practice, which typically involves submitting your ARRT certification along with a state application. Requirements vary, but this step rarely adds significant time if you’ve already passed your boards.
Keeping Your Credentials Current
Once certified, you’ll need to complete 24 continuing education credits every two years to maintain your ARRT credential. This applies regardless of how many ARRT credentials you hold. The requirement is manageable for working technologists and can be fulfilled through online courses, conferences, or in-service training at your workplace.
Adding Specializations Later
After working as a general radiology tech, many professionals pursue additional credentials in areas like MRI, CT, or mammography. These postprimary certifications require structured education, clinical experience in the specialty, and passing another ARRT exam. The ARRT doesn’t set a fixed timeline for completion, so how long it takes depends on your pace and access to clinical training in that modality. Some employers sponsor this training on the job, letting you gain experience during paid work hours. Others may require you to complete a formal certificate program, which can range from several months to a year.
These specialty credentials typically come with higher pay and more career flexibility, making them a worthwhile investment for techs who want to advance without going back for a full degree.
