Certified Carpet Stain Removal Technician (CRI) The CRI exam demands real-world competency with protein-based, oil-based, and synthetic stains—you’ll cover live scenarios involving commercial carpets, delicate fibers, and time-sensitive extractions. Lab components test chemical mixing ratios, equipment pressure settings, and recovery techniques under actual conditions, not just theory. Passing requires proven proficiency across multiple fiber types and contamination levels.
