The Importance of Certification

Patients rarely meet Central Service (CS) professionals, but they rely on them just the same. They count on technicians for clean, sterile, well-functioning instruments. They count on them to follow best practices and stay ahead of the technology curve.

Certification helps meet these expectations and ensures that CS professionals possess the essential knowledge and skills necessary for managing critical departmental duties safely, effectively and consistently. What's more, the ongoing education required for CS professionals to maintain their certification status helps ensure that these professionals stay on top of ever-evolving instrumentation, technology, standards and best practices to keep CS departments functioning at peak performance.

IAHCSMM began formal certification of CS technicians in 1971 to provide a mechanism for individuals to be recognized as having the necessary competence to perform their duties as Central Service professionals.

Learn How to Apply for New Certications, and Renew Current Certifications

IAHCSMM's certifications are offered throughout the year -- we do not have set test dates. Once your application is approved, you will be sent instructions on scheduling a test date and time with our testing provider, Prometric.

Once you earn a certification with IAHCSMM, yearly certification maintenance is required. Thanks to frequent advances in medicine and instrumentation, the Sterile Processing profession, like most medical fields, is rapidly evolving. All IAHCSMM certifications are time-limited to one year, during which the certification holder must show they have pursued continuing education and development.

To remain valid, these certifications must be maintained through the certification renewal process of submitting Continuing Education (CE) credits and applicable renewal processing fees. Certification renewals must be received no later than the last day of the anniversary month of your certification. Any additionally held certifications will also renew that same month (and will require additional CE credits, but no additional fees.)
