Quick answer
Complete an accredited diagnostic medical sonography program, typically a two-year associate’s degree, then pass national registry exams through ARDMS, ARRT, or CCI. Illinois does not require a separate state license. The state median wage was $100,660 in May 2025, with most jobs concentrated around Chicago.
Becoming a sonographer in Illinois follows the same basic path as the rest of the country: finish an accredited diagnostic medical sonography program, pass national registry exams, and start scanning. Illinois does not require a separate state license to work, which is worth knowing up front. What sets Illinois apart is the pay and the geography. The state median wage for sonographers was $100,660 in May 2025, among the higher state medians in the country, and most of the jobs cluster around Chicago.
That $100,660 is the midpoint, not a starting salary. Half of Illinois sonographers earned more, half earned less, and where you land depends on your setting, your specialty, and how long you’ve been working. The rest of this page walks through the program landscape, what the pay actually looks like, and how demand splits between Chicago and the rest of the state.
The quick version
To work as a sonographer in Illinois, the common route is an associate’s degree from an accredited program. That’s the typical entry-level education for the field nationally, according to the U.S. Bureau of Labor Statistics, though certificate and bachelor’s programs also exist.
After the schooling comes certification. National credentialing bodies — ARDMS, ARRT, and CCI — certify sonographers by examination. Illinois does not add a state license requirement on top of that, so the credential you earn nationally is the credential you carry into an Illinois job.
Then comes pay. Illinois sits on the higher end of the state wage table, with a May 2025 median of $100,660. The national median was lower, at $89,340 in May 2024. Different data years, but the gap is real: Illinois runs above the national midpoint.
That’s the surface answer. Here’s the texture underneath it.
What it takes to qualify
The entry point for most people is an accredited diagnostic medical sonography program. BLS lists an associate’s degree as the typical entry-level education, and that’s the most common format you’ll see — a two-year program that combines classroom science with hands-on clinical hours in a hospital or imaging center.
Certificate and bachelor’s programs exist too. Certificates are often built for people who already hold a healthcare credential and want to add sonography. Bachelor’s programs run longer and fold in more general education. The associate’s route is the one most students take.
Accreditation matters here, and it’s worth slowing down on. Programs accredited by CAAHEP (often on the recommendation of JRC-DMS) meet a recognized national standard, and graduating from one keeps the most certification paths open. When you’re comparing Illinois programs, accreditation status is one of the first things to check.
After graduation, you sit for registry exams. Each ARDMS credential, for example, requires passing a physics exam (Sonography Principles and Instrumentation) plus a specialty exam. The credential you earn is national, not Illinois-specific. Pass it, and it travels with you.
Programs in Illinois
Illinois has accredited sonography programs spread across the state, concentrated more heavily in and around the Chicago metro where the population — and the hospital systems — are dense. Community colleges, universities, and hospital-based programs all appear in the mix.
The exact count of Illinois programs shifts as schools gain or lose accreditation, so the most reliable move is to check the current CAAHEP database directly rather than trust a static list. Nationally, CAAHEP listed 390 accredited DMS programs at 275 institutions as of June 2026, with associate’s degrees making up the majority. Illinois is one slice of that national total.
What varies between programs isn’t the credential at the end — that’s national — but the texture of getting there. Program length, cost, how clinical placements are arranged, and how competitive admission is all differ school to school. Some programs have waitlists. Some weight prerequisite grades heavily. The Guide chapter on choosing a program covers what to look at when you compare them.
A practical note on clinicals: sonography programs place students in real imaging departments for hands-on hours, and those placements are easier to arrange where there are more facilities. That’s part of why programs cluster near population centers.
What sonographers earn in Illinois
The Illinois numbers are specific, and they come from BLS state wage data for May 2025.
| Illinois sonographer pay (May 2025) | Annual wage |
|---|---|
| Lowest-paid 10% | $78,350 |
| Median (midpoint) | $100,660 |
| Highest-paid 10% | $122,680 |
Read the spread, then the median. The middle figure, $100,660, is where the typical Illinois sonographer sits. But the range runs from about $78,000 at the lower edge to roughly $123,000 at the top. That’s a spread of more than $44,000 between the bottom and top tenths.
A new graduate tends to land lower in that range. Pay climbs with experience, added credentials, and moves into specialized or lead roles. The percentile figures are a snapshot of the whole workforce at once — first-year sonographers and twenty-year veterans counted in the same dataset.
For comparison, the national median was $89,340 in May 2024. Illinois’s $100,660 sits above that, though the two figures are a year apart and shouldn’t be read as a clean same-year comparison. The broad takeaway holds: Illinois pays above the national midpoint for this field.
BLS reported about 3,270 sonographers employed in Illinois in May 2025. That’s the size of the workforce the wage figures describe.
Chicago vs. downstate
Illinois isn’t one job market. The Chicago metro and the rest of the state look different, and the difference shows up in both the number of jobs and what they pay.
Most sonographer jobs in Illinois are in and around Chicago. The metro holds the large hospital systems, the academic medical centers, and the dense network of outpatient imaging clinics. More facilities means more positions, more specialties hiring, and generally more competition for the higher-paying outpatient and specialized roles.
Downstate — Springfield, Peoria, Champaign-Urbana, the Quad Cities region, and the smaller communities between them — has fewer facilities and fewer openings. The work exists; there are hospitals and clinics across the state that need sonographers. There’s just less of it, and the mix of available specialties can be narrower.
Pay tends to track this. Metro areas with higher costs of living often post higher wages, while smaller markets may sit lower. The KB doesn’t carry a Chicago-specific or downstate-specific wage figure, so that pattern is described in general terms here rather than pinned to an exact metro number. If a precise Chicago-vs-downstate figure matters to you, BLS publishes metropolitan-area wage data worth checking directly.
One thing cost of living complicates: a higher Chicago paycheck doesn’t automatically mean more money in your pocket. Rent and daily costs run higher in the metro. A downstate salary in a lower-cost town can stretch further than the raw number suggests. The question worth sitting with is what a given wage actually buys in the place you’d live.
Do you need an Illinois license?
No. As of 2026, exactly four U.S. states mandate that sonographers hold a state license — New Mexico, Oregon, North Dakota, and New Hampshire. Illinois is not one of them.
That means in Illinois, your national certification is what qualifies you to work. There’s no separate state board exam or state license fee specific to sonographers to clear before you can scan. Employers set their own requirements, and most look for national credentials like the RDMS, RDCS, or RVT.
This can change. State legislatures revisit licensure from time to time, and the list of mandating states has grown over the years. The current count comes from a 2026 capture of state licensure tracking, so it reflects the rules as they stood then. Anyone relying on it for a real decision should confirm the current status with Illinois state authorities, since regulations get updated.
The honest caveats
A few things sit outside the clean numbers.
The wage figures are medians and percentiles for the whole Illinois workforce. They don’t tell you what a specific employer pays, what a first-year offer looks like, or how much a particular specialty commands. Cardiac, vascular, OB/GYN, abdominal, and other specialties can pay differently, and the state median rolls all of them into one figure.
The work has a physical cost the pay doesn’t mention. Sonographers spend long stretches on their feet, holding a transducer at angles that strain the shoulder, wrist, and neck over time. That’s true in Illinois and everywhere else, and it’s a real part of the job regardless of the paycheck.
And the program landscape is a moving target. Accreditation status, admission competitiveness, waitlists, and cost change year to year. A program that fit a friend three years ago may look different now. The current CAAHEP database and each school’s own admissions office are the sources that stay accurate.
None of this is meant to push the decision either way. Illinois pays well for sonography and has steady demand, especially around Chicago. Whether that adds up to the right move is a question only the person weighing it can answer.
