CRCST Technician Externship

Due to current conditions and restrictions at healthcare facilities, externship opportunities are extremely limited and placement cannot be guaranteed.

Obtaining your HSPA Certified Registered Central Service Technician (CRCST) certification helps Central Service Technicians demonstrate that they possess the essential knowledge and skills necessary for managing critical departmental duties safely, effectively, and consistently. It also ensures that Central Service professionals remain current with evolving instrumentation, technology, standards, and best practices to ensure Central Service departments function effectively.

To obtain your certification, a 400-hour on-site externship in Central Service Technical Training is required. In partnership with CBET, this externship provides central service, operating room, infection control, and material management employees firsthand experience at an approved healthcare facility.
