Pediatric Sonography (PS)

The PS application period is now open and will close August 27, 2024. You can now take your examination online from home. Learn more! 

​​​​​​​​The Pediatric Sonography (PS) examination tests the requisite pediatric sonography knowledge, skills, and abilities essential to Sonography Professionals. If you are a physician interested in applying for the RDMS credential with a PS specialty, please visit the website​ for ARDMS’s physician-centric companion Council, the Alliance for Physician Certification & Advancement (APCA).

To earn a Registered Diagnostic Medical Sonographer (RDMS) credential with a PS specialty, you must pass the Sonography Principles and Instrumentation (SPI) examination and the PS examination within five years.

You must wait until the next administration to retake the PS examination if you do not pass the examination.


The PS examination assesses the knowledge, skills and abilities in the areas of the head, spine, chest, hips/ joints and the male and female genitourinary system of the pediatric patient.

Applicants may pursue the PS specialty under the RDMS credential. Once the PS examination is passed under the selected credential, it cannot be switched.

As a windowed examination, scores for the PS examination will be available approximately 60 days after the close of the administration. For more information, review the “Scoring” tab.

We periodically conduct a PS Practice Analysis update the PS examination to reflect the frequency and importance of PS tasks being performed by Sonography Professionals.

All questions on the Pediatric Sonography (PS) examination will fall under the domains and subdomains listed in the PS content outline. It is essential that you review the PS content outline to understand what will be covered in the examination.

The PS examination is three hours and contains approximately 170 multiple-choice questions, which include hotspot questions. The hotspot questions are Advanced Item Type questions that assess and measure your practical sonography skills.

To earn a Registered Diagnostic Medical Sonographer (RDMS) credential with an PS specialty, you must pass the Sonography Principles and Instrumentation (SPI) examination and the PS examination within five years.

After passing the SPI examination, you can earn additional credentials without having to retake the SPI examination, provided you maintain active status.

Note: The PS Examination is a windowed examination. Therefore, it is only offered during select periods of the year. Please refer to the “Schedule” tab for upcoming dates.

ARDMS functions under policies intended to demonstrate impartiality, high ethical standards and validity of its certification assessments. ARDMS does not restrict Applicants, Candidates or becoming a Registrant based on limiting conditions, such as membership of an association or professional society of any organization. ARDMS will not unfairly impede or inhibit access to its certification to Applicants, Candidates or Registrants who meet our stated policies regarding qualification requirements, renewal requirements and/or passing ARDMS’ psychometrically sound certification assessments.

To earn an RDMS, RDCS, RVT or RMSKS credential, you must pass the SPI examination and a corresponding specialty examination within five years, regardless of sequence. This five-year rule does not apply if you are seeking additional specialties under a credential already earned or if you have already earned a credential with the SPI examination. If you do not complete both examinations within the five-year period, you must retake the examination previously passed.

The five-year rule is based on the calendar year (January 1 through December 31). The five-year period begins the day you pass the first examination, and it includes any time that remains in that year plus the next five years. For example, a candidate who passed the first ARDMS examination on June 6, 2010, is required to pass the second examination by December 31, 2015.


To sit for the PS examination and earn the RDMS credential, First-Time Applicants must select a prerequisite that best meets your education and clinical experience.

Physicians can now apply under the new ARDMS physician prerequisite. Learn more!

Taking a practice test or two is a great way to prepare for your actual examination. We offer a Pediatric Sonography (PS) Practice Test that simulates the computer interface used in the actual test center environment. The PS practice test review is comprised of 30 sample questions and is 30 minutes long.

After you complete a practice test, you will be emailed a report that shows the number of questions you answered correctly. While the report is an indication of your knowledge, the practice tests results should not be used to predict how well you will perform on the actual examination at the test center.

See FAQs for additional information.

Each practice test costs $45 USD.

You can now register for a PS practice test by signing into your MY ARDMS account and clicking the Sign Up/View Practice Test option in the Application Center tab. You can also view the computer system requirements in your MY ARDMS portal. For any general questions or technical problems regarding the practice tests, please call ARDMS at (800) 541-9754 option 1 or email

Before you start your test you should review the test tutorial. Please note you will not get a chance to review the test tutorial during the actual practice test, so please prepare accordingly. Once your session begins, you have 30 minutes to complete the practice test.

Register for a PS practice test, by signing in your MY ARDMS  account.

After all of your diligent preparation and hours spent studying, here are a few valuable tips to help make your examination day a success:

• Double check that you know where the test center is before examination day and give yourself plenty of time to get there. Remember, you MUST arrive and register at least 30 minutes before the examination begins.
• Get a good night’s sleep before you take your examination. Being well rested and relaxed when you take your examination will help you concentrate.
• Bring one form of current and valid identification that complies with the test center identification requirements.
• Travel light. The only thing you can bring into the testing room is you. You can store your personal belongings — your car keys, watch, smartphone, purse, backpack, etc. — in lockers at the test center. The following items are not allowed in test centers: study materials, food, drink, visitors/guests, pets and children.
• Request a white board if you plan to jot down notes during the examination. Test centers are using white boards (rather than paper) in an effort to “go green.”
• Be advised that the use of a calculator for this examination is prohibited.  However, you may utilize the White Board provided at the test center or the digital White Board provided for online proctoring examinations for manual calculations.

Good luck!

​Even though we offer practice examinations and sample questions, we do not offer study materials for our examinations – but our sister organizations do. You can find materials at:

• Society of Diagnostic Medical Sonography
• American Institute of Ultrasound in Medicine
• Society for Vascular Ultrasound
• American Society of Echocardiography

The PS examination features Advanced Item Type questions, which assess and measure your practical sonography skills. They include hotspot questions in which you will receive questions about individual images. You will use the cursor to mark the correct answer directly on the image.

Watch ARDMS Presents: How to Answer a Hotspot Question.


The PS examination evaluates the pediatric sonography knowledge and skills you must demonstrate as a Sonography Professional. The primary test result is a PASS or FAIL decision. In addition, you will receive a scaled score, ranging from 300 to 700. A scaled score of 555 is required to pass all ARDMS examinations.

The scaled score is not a percentage of correct answers, nor is it built on a “curve” where a certain percentage of scores would pass and a certain percentage would fail. To learn more, visit Notification of Results and Scoring.

​Examination results and a full score report will be available approximately 60 days after the close of the examination administration. At that time, an email will be sent to you with instructions on how to access your score report in MY ARDMS.

Candidates receiving a confirmed passing score on all required examinations and meeting all other requirements will be awarded a certification. For information on the ARDMS’ scoring methods, visit Notification of Results and Scoring.

Candidates who do not pass are invited to re-apply.

​When submitting your ARDMS application, you consent to us releasing your examination results to your educational program.

Program Directors can receive a School Report for current programs and programs completed in the past three years. To learn more, visit School Reports.

You can request a score verification for a $35 USD fee, payable by check, money order or credit card. Score verification ensures that the computer counted the correct and incorrect answers appropriately, but it does not review the questions and answers.

You must submit the completed Exam Score Verification Form within 30 days of having taken the examination in question. The Exam Score Verification Form will be returned if incomplete, unsigned or unpaid.

When deciding whether to have your score verified, please consider that ARDMS examinations are scored electronically with a high degree of accuracy, and it is unlikely that verification will alter your original score.

ARDMS certification examinations are developed to assess the knowledge and skills necessary to practice the specialty safely and competently.
