State Overview
Montana licenses radiology as more than a single credential. Alongside the general radiologic technologist license, it recognizes a limited-permit tier (Limited Permit X-ray Operator).
A few other modalities are credentialed by the hiring facility or not licensed by the state at all, rather than carrying their own Montana license. The specialty section below covers each, including where a single-modality candidate may not be placeable.
Across radiology, ARRT certification is the national credential that anchors state licensure. A license you hold in another state does not transfer automatically, so you apply directly to Montana's licensing board for each assignment.
General Requirements
If you perform radiology procedures in Montana, the baseline below applies regardless of where you trained or which modality you work in.
- National certification: an active ARRT credential is the prerequisite the state license is built on. The state credential sits on top of ARRT, not instead of it.
- Credential required: ARRT (R).
- Scope of the base license: Performs diagnostic x-ray procedures on people. Requires passing the ARRT examination and a board-approved 24-month course of study.
- Verification: ARRT or direct board verification.
Fees & Credentials
Montana issues more than one radiology credential, so fees vary by what you actually do. The table below is one row per state-recognized credential.
| Credential | Application | Renewal | Cycle |
|---|---|---|---|
| Radiologic Technologist | $100 | $75 | Every 1 year |
| Limited Permit X-ray Operator | $100 | $60 | Every 1 year |
There is no state fee line for MRI Technologist and Sonography, because Montana does not license those modalities. Their absence from the table is the point, not an omission.
$100 application (ARM 24.204.401); $75 ANNUAL renewal, expires Feb 1.
Renewal & Continuing Education
- Renewal cycle: every 1 year, every year prior to February 1st.
- Continuing education: your CE is whatever ARRT requires to keep your credential active. Montana does not appear to add its own hour mandate for the general license.
- Limited Permit X-ray Operator CE: 6 hours per license year (versus the ARRT 24-per-biennium model for the full license).
Getting Licensed
Radiology licensure is ARRT-primary, so the path is shorter than the multi-step endorsement other professions run. For most candidates it is four steps:
- Hold the right ARRT credential for the work you will do (Radiography for general x-ray; the matching post-primary credential for a modality the state licenses).
- Complete a board-approved program if the state requires one for your credential.
- Apply to Montana Department of Public Health and Human Services through the application portal.
- Have ARRT verify your credential to the board directly. You do not self-attest the certification.
Common slip-ups travelers hit here: incomplete ARRT verification or failure to request verification directly from ARRT when license held in another state; board requires proof of current ARRT registration before processing.
Processing & Timing
Board processing time is how long the board takes once it has a complete application. Montana does not publish a standard turnaround for radiology, so plan from recruiter experience rather than a board SLA.
Recommended lead time before your start date is the total runway, and it runs longer than the board's processing window. Start the application as early as you can, because your ARRT verification has to reach the board before it can act.
If you need more than one credential here, for example a base license plus an add-on authorization, they may process as separate items rather than in one pass. Do not assume you can layer the second credential on at the last minute.
Montana requires permanent licensure before practice begins and has no temporary license pathway. Endorsement processing (3-6 weeks typical) combined with ARRT verification and board meeting cycles creates moderate-to-high placement risk if lead time is shorter than 10 weeks.
Specialty Differences
Most of the radiology family in Montana runs on the general license. A handful of credentials genuinely diverge, and those are the ones worth reading closely. Below is one subsection per real difference, then roll-up lines for everything else.
Limited Permit X-ray Operator
Divergence: limited-scope tier. Performs a limited scope of x-ray procedures restricted to specific body-part and exam categories.
- Fee: $100 application, $60 renewal, every 1 year
- Credential: Board-approved limited course (no full ARRT registration)
- CE: 6 hours per license year (versus the ARRT 24-per-biennium model for the full license)
How it differs from the general license: A lower education bar (a minimum 104-hour board-approved course, or half of an ARRT-recognized program, instead of a 24-month degree), no full ARRT registration, a lower renewal fee, lower CE, and a scope limited to the specific exam categories the holder qualifies for.
CT Technologist
Divergence: facility-credentialed. CT credentialing is the hiring facility’s responsibility; Montana issues no CT license or permit.
- Credential: ARRT (CT) post-primary, set by the facility
How it differs from the general license: The CT modality is not state-regulated, though a primary-pathway CT technologist still needs the underlying Montana radiography license.
MRI Technologist
Divergence: no state credential. MRI uses no ionizing radiation, so it falls completely outside Montana’s x-ray-only statute. No Montana license or permit exists for MRI techs.
- Credential: ARRT (MR) or ARMRIT (employer-set, no state credential)
How it differs from the general license: An MRI-only technologist needs no Montana state license whatsoever. Per the board FAQ, someone without an ARRT Radiography credential would not need a Montana radiologic technologist license.
Sonography
Divergence: no state credential. Ultrasound uses no ionizing radiation and sits outside the x-ray-only statute. Montana issues no license or permit for sonographers.
- Credential: ARDMS (employer-set, no state credential)
How it differs from the general license: A sonographer needs no Montana state license, the same posture as MRI.
Credentialed by the facility, not the state
Montana does not separately license these modalities. The hiring facility credentials them against your ARRT post-primary certification, and you still need the general radiologic technologist license underneath: Radiation Therapy, Nuclear Medicine, and Mammography.
Before you pay: confirm your modality
Within radiology, whether a modality needs its own state credential is not consistent, and it is the thing travelers most often get wrong. MRI, nuclear medicine, radiation therapy, sonography, and CT can each be a separate state license in one state, a facility credential checked against your ARRT registration in the next, and nothing extra in a third.
The divergences we verified for Montana are above. What we cannot see is your specific assignment and the site you land at. Before you submit any application fee for an advanced modality, confirm with your recruiter whether Montana issues a state credential for it or whether the facility handles that against your certification. We would rather you ask first than pay for something the role never required.
