If you are weighing a career as a radiologic technologist against a career as a respiratory therapist, the headline numbers come down to three variables: how long the training takes, what the certification examination demands of you, and what the work pays. This page puts the BLS May 2024 OEWS national medians, projected growth rates, and employment counts for both occupations side by side, then walks through the practical implications for a candidate currently choosing between the two.
| Radiologic Technologist | Respiratory Therapist | |
|---|---|---|
| SOC code | 29-2034 | 29-1126 |
| National median wage | $67,000 | $78,000 |
| U.S. employment | 222,000 | 137,000 |
| Projected 10-year growth | 6% | 13% |
| Typical entry education | Associate degree in radiologic technology (24 months) | Associate or bachelor degree in respiratory care (24-48 months) |
| Primary credential | ARRT R | CRT (NBRC) |
| Primary certifying body | American Registry of Radiologic Technologists (ARRT) | National Board for Respiratory Care (NBRC) |
| Renewal cycle | Annual registration, with biennial CE compliance | Every 24 months (2 years) |
Pay and Outlook
Respiratory Therapists earn approximately $11,000 more than radiologic technologists at the national median ($78,000 versus $67,000). The pay gap reflects two structural differences: training depth (a longer training program or a more rigorous certification examination usually correlates with higher entry pay) and clinical acuity (roles that work directly with critically-ill patients in hospital settings typically out-pay roles concentrated in outpatient clinics or front-office settings, even when the title sounds similar). Projected ten-year growth is 6% for radiologic technologists and 13% for respiratory therapists — a 7-point spread that, applied to a hundred-thousand-job national base, translates into thousands of additional or fewer openings per year over the projection horizon.
Training Investment
Entry into the radiologic technologist role typically requires a Associate degree in radiologic technology (24 months) commitment, while the respiratory therapist path runs Associate or bachelor degree in respiratory care (24-48 months). Translate that into months of opportunity cost — tuition you pay plus wages you forgo while studying — and you can usually identify which role makes financial sense for your specific situation. Candidates in their early twenties with no dependents and access to financial aid often opt for the longer-training, higher-paying role; candidates supporting a family who need to be in the workforce within months typically opt for the shorter pathway, with the option to upgrade later via stacked credentials or a part-time degree completion program.
The Certification Examination
Radiologic Technologists sit for the ARRT Radiography Certification Examination, administered by American Registry of Radiologic Technologists (ARRT). The format is: 200 multiple-choice items across Patient Care, Safety, Image Production, Procedures; computer-based, 3.5 hours. Respiratory Therapists sit for the Therapist Multiple-Choice (TMC) Examination plus Clinical Simulation Examination, administered by National Board for Respiratory Care (NBRC). The format is: TMC: 160 multiple-choice items, 3 hours. CSE: 22 clinical simulation problems, 4 hours.. The structural differences in exam format — number of items, time allowed, single examination versus multiple components, computer-based versus computer-adaptive scoring — are worth understanding before you commit to one preparation pathway, because they imply quite different study patterns and stamina demands on test day.
Renewal and Continuing Education
Once certified, the ARRT R renews on a Annual registration, with biennial CE compliance cycle with 24 contact hours every 2 years (biennial). The CRT (NBRC) renews on a Every 24 months (2 years) cycle with 30 contact hours per cycle (NBRC Continuing Competency Program). Practitioners who plan to maintain both credentials in parallel — a relatively common pattern for candidates who start in the shorter-training role and bridge into the longer-training role over their first three to five years of practice — should map out the two renewal cycles together to avoid stacking continuing-education deadlines that could otherwise create real workload pressure in any given year.
Credential Transferability
A practical question for any candidate weighing two roles is: how easily does training in one transfer to the other if I change my mind? In general, both radiologic technologist and respiratory therapist training share a common foundation in vital signs, infection control, medical terminology, basic life support, HIPAA, and patient communication — typically the first eight to twelve weeks of either curriculum. Beyond that point, the curricula diverge into role-specific clinical skills. Candidates who have completed one program and choose to bridge into the other usually receive transcript credit for that shared foundation, reducing total time-to-completion of the second credential by roughly twenty to thirty percent. State licensing boards, where applicable, treat the two credentials as separate licenses, so completing one does not exempt you from independently meeting the application, examination, and fee requirements of the other.
Which Role Suits Whom
Practitioners who thrive as radiologic technologists tend to be drawn to radiologic technologists perform diagnostic imaging examinations, primarily x-ray, with cross-training opportunities in computed tomography, magnetic resonance imaging, mammography, and interventional radiology. they are… Practitioners who thrive as respiratory therapists tend to be drawn to respiratory therapists evaluate, treat, and care for patients with breathing or other cardiopulmonary disorders. they manage mechanical ventilators in intensive care units, deliver aerosolized medications, perform pulmon… If you are evaluating both, the most useful next step is to shadow a working practitioner in each role for a single shift before committing to a training program. Most local hospitals and outpatient clinics will accommodate a four-hour shadow visit if you contact human resources or the relevant department manager directly.
