Certified Subfloor Preparation Technician (ICRI) The ICRI exam cuts deeper than surface-level floor knowledge. You’ll navigate concrete diagnostics, moisture remediation protocols, and substrate compatibility issues that separate professionals from novices. Expect rigorous questions on polymer-modified underlayments and failure analysis—topics that expose gaps in practical experience quickly.
