Reading the answer for your state

The large word answers the most asked question: does an x-ray technologist need a state credential there? Under it, the same answer for sonographers and for limited x-ray operators, the other modalities the state licenses (CT, MRI, nuclear medicine, radiation therapy…), the agency, and the number of radiography and sonography programs that reported graduates. Each state page adds the steps to apply, the fees printed on the agency page, and the largest schools with their tuition. The method page explains each source.

Licensing in medical imaging depends on the modality and on the state. Read on November 13, 2026, the state table of the American Society of Radiologic Technologists shows that 37 jurisdictions issue a license, certificate or permit to radiographers, 2 more an accreditation or registration (Illinois, Mississippi), 4 rely on a training standard without a license, and 8 have no rule for the profession (Alabama, Alaska, Idaho, Michigan, Missouri, North Carolina, Oklahoma, South Dakota). Sonography is licensed in only 5 jurisdictions: District of Columbia, New Hampshire, New Mexico, North Dakota, Oregon. Limited x-ray operators have a state credential in 27. The national credentials sit on top: an ARRT primary application costs $225; ARDMS charges $275 for the SPI exam and $300 for each specialty. In the federal IPEDS files, 482 radiography and 311 sonography programs reported graduates for 2023-24. In Texas, the example, a radiographer needs a state certification, a sonographer no license, and 83 programs reported graduates.

Sonographer and rad tech license by state: four kinds of states

States with a radiography license. 37 jurisdictions issue a license, a certification, a certificate or a permit. The word changes, the rule does not: you cannot take x-rays there without it. Most grant it on the strength of the ARRT exam. See the rad tech license by state.

Accreditation or registration. Illinois accredits technologists through its Emergency Management Agency ($120 for two years); Mississippi registers them. Same effect, different name.

A standard without a license. Colorado, Georgia, Minnesota, Pennsylvania expect education or national credentials but issue no license. Colorado says it plainly: it is a non-licensure state for ARRT-certified technologists.

No rule. Alabama, Alaska, Idaho, Michigan, Missouri, North Carolina, Oklahoma, South Dakota: nothing to file with the state, and employers hire on ARRT.

Sonographers: five licensing jurisdictions

District of Columbia, New Hampshire, New Mexico, North Dakota, Oregon license sonography; 46 do not. Everywhere, the ARDMS exams (SPI and a specialty, within 5 years) or the ARRT sonography discipline are what employers look for. Read the sonographer guide and the sonographer license by state.

Exams, schools and moving

The ARDMS cost calculator and the ARRT fee calculator add up the national fees. How to become an ultrasound tech and radiology tech schools list the programs of each state. Limited x-ray licenses cover the shorter route, and moving to another state what changes when you cross a state line.

ARRT and ARDMS: the national credentials

ARRT certifies and registers radiologic technologists in radiography and in other disciplines, sonography among them. Its application fees, read on its Application Fees page: $225 for a primary discipline, $225 for a postprimary one, $450 for a postprimary discipline earned through an ARDMS or NMTCB credential. Certification is renewed every year, by the last day of the birth month, with continuing education every two years (biennium) and Continuing Qualifications Requirements every 10 years for R.T.s certified since January 1, 2011 (ARRT ongoing requirements). ARRT also administers state licensing exams for many states, and developed three exams specifically for them: limited scope radiography, bone densitometry equipment operator and fluoroscopy (ARRT state licensing).

ARDMS, run by Inteleos, credentials sonographers: RDMS (abdomen, obstetrics and gynecology and other specialties), RDCS (echocardiography) and RVT (vascular technology). Each needs the SPI exam ($275) and a specialty exam ($300), passed within 5 years of each other. Renewal is every year, fees due by December 31 (renewal opens in September) (Inteleos renewal page).

Where the programs are

The IPEDS completions file counts, for every college that takes federal student aid, the awards of each program. For July 2023 to June 2024, 482 radiography programs reported 11,531 awards and 311 sonography programs 7,049 (IPEDS C2024_A). The states that trained the most imaging graduates were California (2,842), Texas (2,537), Florida (2,033), New York (952), Illinois (629). District of Columbia, Hawaii reported none. Median in-state tuition and fees at public schools were $4,868 a year in radiography and $4,916 in sonography (IPEDS IC2023_AY).

What this site does not know

14 agency sites refused our reader or did not answer; their states rely on the ASRT table alone, and each of those pages says so. The site does not show license fees that a state page did not print, the annual renewal amounts of ARRT and ARDMS (not on a page we could read), salaries, or anything medical. Hospital programs outside federal student aid are missing from the school counts. Read more on the method page.

Questions students and technologists ask

Tap a question to see the answer.

Do sonographers need a license in every state?

No. Only District of Columbia, New Hampshire, New Mexico, North Dakota, Oregon issue a sonography license, according to the ASRT table read on November 13, 2026. Elsewhere there is nothing to file with the state, and employers ask for an ARDMS or ARRT sonography credential instead.

Is this an official licensing site?

No. Sonographer By State is an independent site published by Radif Partners. It is not a state board, not ARRT, not ARDMS and not the ASRT. It reads their pages and links to each one, so you can check the source before you apply.

Why does a state say “refused our reader”?

Because the agency site of that state, 14 of 51 in all, answered our request with a refusal or not at all. We did not work around it. For those states, the answer comes from the ASRT table alone; contact the agency before you rely on it for a job.

How much do the national exams cost?

ARRT charges $225 for a primary discipline application, $225 for a postprimary one. ARDMS charges $275 for the SPI exam and $300 for each specialty exam, so $575 for a first credential. State fees come on top where a state license exists.

Does this site show salaries?

No. Pay depends on the employer, the region and the shift, and the pages that list it are built for other purposes. This site covers what a state and the credentialing bodies require, what that costs, and where to train.

How current are the school figures?

The programs and awards come from the IPEDS completions file for July 2023 to June 2024, and the tuition and fees from the 2023-24 charges file, both downloaded from NCES on November 13, 2026. They are the latest complete files published; a school’s current price may differ.
