The Sonography Canada Core Sonographic Skills Examination is a mandatory credentialing assessment administered by Sonography Canada. Passing this exam is a prerequisite for candidates seeking professional credentials such as the Canadian Registered General Sonographer (CRGS), Canadian Registered Cardiac Sonographer (CRCS), or Canadian Registered Vascular Sonographer (CRVS). The assessment ensures that all entry-level sonographers possess the fundamental knowledge required for safe and effective practice.
(Note: Sonography Canada is transitioning to a new integrated format (NCP 7.0) beginning in 2027. This guide covers the current standalone Core exam based on the NCP 6.1 blueprint).
Unlike specialty exams that focus purely on anatomy, the Core exam demands a high-level understanding of ultrasound physics, instrumentation, and patient care. You will be evaluated on your ability to optimize image quality, recognize artifacts, manage bioeffects, and navigate ethical patient interactions. By utilizing a targeted study guide, practice tests, and active exam review, you can familiarize yourself with the formatting of the multiple-choice questions and improve your readiness for this high-stakes foundational exam.
The official Sonography Canada Core blueprint evaluates candidates across several fundamental domains. Engaging with these practice test modules will ensure you are well-prepared for the theoretical components of your credentialing process.
This module covers the core concepts of sound waves, frequency, wavelength, and propagation through various tissue mediums. Practicing these scenarios helps you master the science behind the acoustic variables necessary for diagnostic imaging.

Sonographers must understand their equipment. This test bank quizzes you on piezoelectric properties, transducer construction, array types, and how adjusting system controls (like gain and time-gain compensation) impacts image resolution.
This section evaluates your ability to understand blood flow dynamics, the Doppler shift, and spectral analysis. You will practice identifying the differences between continuous wave, pulsed wave, color, and power Doppler modalities.
Recognizing artifacts is essential for accurate diagnoses. This module tests your ability to identify and correct common image artifacts such as reverberation, shadowing, enhancement, and aliasing, distinguishing them from true pathology.
Patient safety is paramount. This module covers the thermal and mechanical indices (TI and MI), ALARA principles (As Low As Reasonably Achievable), and the potential biological effects of ultrasound exposure.
Technical skill is only half the job. This crucial module quizzes you on patient assessment, vital signs, obtaining informed consent, and professional communication strategies for diverse and vulnerable populations.
Maintaining a sterile environment protects both you and the patient. This module covers standard precautions, transducer disinfection protocols, handling hazardous materials, and occupational health and safety standards.
Navigating the legal framework of healthcare in Canada is non-negotiable. This section trains you on the Sonography Canada Code of Ethics, patient confidentiality (e.g., PIPEDA), and the legal responsibilities of a diagnostic medical sonographer.
Question 1:
When adjusting the imaging parameters on an ultrasound machine, a sonographer decides to increase the operating frequency of the transducer. How will this change affect the resulting image?
A) It will increase penetration and decrease axial resolution.
B) It will decrease penetration and improve axial resolution.
C) It will increase both penetration and lateral resolution.
D) It will have no effect on penetration but will improve temporal resolution.
Answer and Explanation:
The correct answer is B) It will decrease penetration and improve axial resolution. In the Physical Principles of Ultrasound domain, it is a fundamental rule that higher frequency sound waves provide better image detail (axial resolution) but attenuate more quickly, leading to decreased depth of penetration. This is why low-frequency transducers are used for deep abdominal imaging, while high-frequency transducers are used for superficial structures.

Question 2:
While performing a spectral Doppler examination of the carotid artery, the sonographer notices that the peak of the waveform is wrapping around to the bottom of the baseline. What is the most appropriate initial adjustment to correct this specific artifact?
A) Decrease the Doppler gain.
B) Increase the wall filter.
C) Increase the pulse repetition frequency (scale).
D) Decrease the operating frequency of the transducer.
The correct answer is C) Increase the pulse repetition frequency (scale). The artifact described is aliasing, which occurs when the Doppler shift exceeds the Nyquist limit (one-half of the pulse repetition frequency). The most direct and common way to correct aliasing is to increase the scale (PRF). Decreasing the baseline is also an option, but it was not listed.

Question 3:
According to standard infection control protocols and Sonography Canada guidelines, which level of disinfection is required for an endocavitary (transvaginal or transrectal) ultrasound transducer between patients?
A) Low-level disinfection (e.g., wiping with a standard hospital-grade germicidal wipe).
B) Intermediate-level disinfection (e.g., wiping with a diluted bleach solution).
C) High-level disinfection (e.g., soaking in glutaraldehyde or using an automated hydrogen peroxide system).
D) Sterilization (e.g., steam autoclaving).
The correct answer is C) High-level disinfection (e.g., soaking in glutaraldehyde or using an automated hydrogen peroxide system). Endocavitary probes are considered semi-critical devices because they come into contact with intact mucous membranes. Therefore, they require high-level disinfection to destroy all microorganisms (except for large numbers of bacterial spores) to ensure patient safety.

Question 4:
A sonographer is preparing to scan an anxious, elderly patient who is hard of hearing. Before beginning the exam, the sonographer must obtain informed consent. Which of the following approaches is most appropriate?
A) Speak loudly from across the room to ensure the patient hears the explanation.
B) Assume implied consent since the patient arrived for the appointment and begin the exam.
C) Face the patient directly, speak clearly at a moderate pace in a lower pitch, and ensure they understand the procedure before proceeding.
D) Ask the patient's accompanying family member to provide consent on their behalf, ignoring the patient.
The correct answer is C) Face the patient directly, speak clearly at a moderate pace in a lower pitch, and ensure they understand the procedure before proceeding. Patient Care and Communication guidelines require sonographers to adapt their communication style to meet the patient's needs. Facing the patient aids in lip-reading, and lower pitches are often easier for elderly patients to hear. Competent adults must always provide their own informed consent.

The Sonography Canada Core Examination is a standardized, multiple-choice assessment that tests entry-level knowledge in ultrasound physics, instrumentation, patient care, safety, and professional ethics based on the National Competency Profile (NCP 6.1).
It is officially administered by Sonography Canada, the national credentialing body and professional association for diagnostic medical sonographers in Canada. Exams are delivered via computer-based testing at designated centers.
Passing the Core exam is a strict requirement for earning any of the primary Sonography Canada credentials (CRGS, CRCS, CRVS). Without passing this foundational exam, you cannot become a fully credentialed sonographer in Canada.
Yes, passing the Core exam and earning a Sonography Canada credential is the gold standard for employment in Canadian hospitals and clinics. It is often a legal requirement for employment, depending on provincial regulations.
Advisory: Mastering Physics and Instrumentation
Many candidates struggle with the physics portion of the Core exam because it requires conceptual understanding rather than simple memorization. You must understand why an artifact occurs and how to fix it using machine controls. To improve your readiness, do not just memorize formulas (like the Doppler equation); practice applying them to clinical scenarios. Relate the physics concepts back to the physical buttons on the ultrasound machine you use in your clinical practicum.
The Sonography Canada Core Exam utilizes a scaled scoring system to ensure fairness across different versions of the test.
