Instrumentation Identification
Differentiate surgical instruments, identify specialty instrumentation, manufacturing types, and implantable devices.
Instrumentation Inspection, Testing, Integrity & Assembly
Evaluate process compliance, select inspection/testing tools, perform visual and integrity inspection, facilitate PM and repairs.
Preparation and Packaging
Evaluate and select packaging systems and sterilization compatibility; apply sterilization and disinfection standards and troubleshoot failures; promote training, process improvement, audits, and documentation.
Sample CIS questions

Question 2
Which document should guide cleaning for a specialty instrument?
Why: Specialty instruments often have validated cleaning requirements that must be followed exactly.
Question 3
What should happen to a damaged instrument?
Why: Damaged instruments can compromise patient safety and surgical workflow.
Frequently asked questions
Who is CIS practice for?
CIS practice is for technicians preparing for the Certified Instrument Specialist exam or strengthening surgical instrument knowledge after CRCST.
Does CIS require instrument identification?
Yes. Instrument identification is a major part of CIS preparation, alongside inspection, testing, assembly, decontamination, and packaging.
Should I complete CRCST first?
HSPA specialty certifications generally build on CRCST status, so most candidates use CRCST as the foundation before CIS.
