Sonography Principles and Instrumentation – ARDMS SPI Exam

To earn an ARDMS credential, Applicants must choose and meet the requirements of a prerequisite. Review the Prerequisite Prep tool to help guide you through the prerequisite selection process and to select a prerequisite that best meets your education and clinical ultrasound experience.

Re-Applicant – A re-applicant is a Candidate or Registrant who has previously applied and been approved by ARDMS to take or has taken an ARDMS examination and who is applying to take another examination; this does not include an individual who has only been approved for MSKS, MW examinations and approval of the Sonography Principles & Instrumentation (SPI) examination under the SPI Examination Requirement Pathway. Re-applicants should apply as such and thus this guide isn’t necessary for you.

Once you are ready to apply for an ARDMS examination, follow the steps below:

1. Log in to MY ARDMS and choose the “Apply Online” option.
2. Complete the online application form and submit payment. If you are a first-time applicant, you are required to select the SPI requirement or a prerequisite​ under which to apply.
3. Gather your supporting documentation and submit at time of application
4. To upload your documentation to your MY ARDMS account, click the “My Resources” tab, then “Upload Documents”. For “File Type” select “Application Documents”

For more details, please visit the ARDMS How to Apply Guide.

Once we have reviewed your information, we will email you with either an Examination Confirmation Letter (ECL) or a request for additional documentation. When you receive the ECL, you may contact Pearson VUE to schedule an examination appointment during your eligibility period.

If you are found ineligible to take the examination, your application will be partially refunded (less the $100 USD processing fee per examination).

The required supporting documents depend on your chosen prerequisite and must be submitted online with your application.

Please note: We do not review application documentation received prior to receipt and payment of the online application.

ARDMS provides reasonable testing accommodations in compliance with the Americans with Disabilities Act (ADA) .  Under the ADA, a disability is a physical or mental impairment that substantially limits one or more major life activities. Having a diagnosed impairment does not necessarily mean that an individual is disabled as defined by the ADA, and not all disabilities require test accommodations.

For more information regarding the ARDMS testing accommodations program, including documentation requirements, processing timelines, and types of accommodations offered, please read the ARDMS Test Accommodations page.

• Provide a digital signature
• Have your palm vein scanned
• Take a test-day photograph

Note: The only thing that you can bring into the testing room is you. The test centers have lockers you can use to store personal belongings. Study materials as well as food and drink are prohibited in the test center. No visitors, guests, pets or children are allowed.

Important: Review ARDMS’ Examination Admission Compliance Policies to ensure you are not refused admission at the test center and do not conduct unauthorized examination behavior.

Test centers will provide white boards for notes during the examination upon request.

If you have a documented disability and require special accommodations, contact ARDMS for pre-approval prior to making an examination reservation.

Each practice test costs $45 USD.

You can now register for a SPI 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 for assistance.

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 SPI practice test, by signing in your MY ARDMS  account.

The SPI examination covers the following content areas. All percentages are an approximate distribution of the questions across the content areas.

Please note: All percentages are approximate.

SPI Content Outline

• Perform Ultrasound Examinations – 23%
• Manage Ultrasound Transducers – 7%
• Optimize Sonographic Images – 26%
• Apply Doppler Concepts – 34%
• Provide Clinical Safety & Quality Assurance – 10%

Your score report will display and include performance feedback for these content areas.

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

1. 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.
2. 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.
3. Bring one form of current and valid identification that complies with the test center identification requirements.
4. 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.
5. 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.”
6. 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 exams and sample questions, we do not offer study materials for our exams – but our sister societies offer resources that could help you prepare. You can find materials at:

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

You can receive a score report at the test center once you complete the examination. Additionally, your score report will be available in your Pearson VUE account. The Pass or Fail results will then be posted to your secure MY ARDMS account within the next week.

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

Candidates who do not pass are invited to re-apply but must wait 60 days between attempts.

​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.
