CCPU Certification Register

The ASUM CCPU Certification Register recognises our dedicated members who have demonstrated a commitment to the practise of ultrasound, by initially completing the Certificate of Clinician Performed Ultrasound (CCPU) as well as those who continue to meet the recertification requirements every five years. Recertification is intended to reaffirm a practitioner’s standing as a leader in his or her specialty and demonstrates that the practitioner is continuing to practice in the relevant area of study, thus maintaining currency with the knowledge and practical experience required to maintain competency.

This register is correct as of 29 September 2025.
