Obstetrics ＆ Gynecology (OB/GYN)

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.

To verify whether or not you are a Re-applicant for this examination, please log into MY APCA  and view your “Current Status.” Please follow the key below:
• Candidate: Re-applicant
• First-time Applicant: First-time Applicant
• Non-member: First-time Applicant
• Registrant: Re-applicant
• Student: Please contact the ARDMS office to verify your status

You will be considered a Re-applicant for the OB/GYN examination:
• If you were previously approved to sit for any specialty examination (excluding MSK and
PVI)
• If you were previously approved to sit for the SPI examination under a prerequisite
(excludes approval of the SPI examination under the SPI Examination Requirement)

To apply as a Re-applicant:
• If you have a current OB/GYN Clinical Verification (CV) Form on file, you will need to
submit the application and examination fee only. The application will automatically be
approved.
• If you do not have a current OB/GYN CV Form on file, you will need to submit the
application, the examination fee and a current OB/GYN CV Form. To access your active CV
Forms, please log into MY APCA​ and click on “Clinical Verification Form” under
“Application Center.”

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
• American College of Nursing- Midwives ​

The OB/GYN 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. Find out more about the OB/GYN PACSim questions​.

Watch the video presented by APCA’s companion organization for sonographers, ARDMS: How to Answer a Hotspot Question.

​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 APCA​ 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.

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 examinations are scored electronically with a high degree of accuracy, and it is unlikely that verification will alter your original score.
