Master endoscope reprocessing — and earn your national certification
A clinically rigorous, step-by-step program built around the CBSPD CFER and HSPA CER exam domains — so working sterile processing and GI lab professionals can study smart, validate their skills, and walk into the exam room ready.

"Reprocessing is a clinical discipline — and you deserve education that treats it like one."
— Nathan Hostetter

Who it's for
Is this you?
Sterile processing tech seeking specialty creds
Already holds a core CS certification and wants the CBSPD CFER to formalize expertise in flexible endoscope reprocessing and advance into a lead role.
GI lab technician formalizing floor knowledge
Has hands-on reprocessing experience but no structured education behind it — needs a curriculum grounded in ANSI/AAMI and SGNA standards to sit confidently for the CER exam.
Central service professional expanding scope
An experienced CS professional whose department is absorbing endoscopy reprocessing and needs rigorous, up-to-date training on HLD protocols, AER operation, and compliance workflows.
New reprocessing staff entering the specialty
Making a deliberate career move into endoscope reprocessing and needs a structured foundation — from Spaulding Classification through storage and chain-of-custody documentation — before stepping onto the floor.
Infection prevention or quality professional
Oversees reprocessing audits and compliance programs and wants deep fluency in the full reprocessing cycle, breach response, and regulatory reporting to strengthen department oversight.
Department educator or preceptor
Responsible for onboarding and competency verification in a reprocessing unit and wants a clinically authoritative reference program to anchor staff training and continuing education.

Nathan Hostetter
If you work in sterile processing or a GI lab, you already know that flexible endoscope reprocessing is not a task you can afford to get wrong. The stakes are real — patient safety, accreditation standing, regulatory compliance, and your own professional credibility are all on the line every time a scope goes through the reprocessing cycle. And yet, structured education in this specialty has historically been hard to come by. Most of us learned by watching someone else, following a posted SOP, and hoping the policies on the wall actually reflected current ANSI/AAMI or SGNA standards.
That's exactly why I built this program. I wanted to create the resource I wish I'd had — one that treats reprocessing as the clinical discipline it is, walks through the science and the standards with precision, and leaves you genuinely confident rather than just technically compliant. Every module in this course reflects current guidelines from ANSI/AAMI, SGNA, ASGE, and the FDA, and it's structured so that the knowledge builds on itself: anatomy informs your cleaning decisions, cleaning decisions shape your HLD outcomes, and HLD outcomes determine patient safety. Nothing is taught in isolation, because in a real reprocessing suite, nothing happens in isolation.
I also know that you're studying on a tight schedule. You're fitting this in between shifts, around family, and alongside the actual demands of your job. So I built this program to be direct and efficient — precise technical vocabulary without unnecessary jargon, clear explanations of the why behind each standard, and a curriculum arc that moves you steadily toward exam day. The CBSPD CFER and HSPA CER exam domains aren't an afterthought here; they're woven into the fabric of every module, and the final domain review gives you a targeted way to check your readiness before you sit down to test.
Whether you're a sterile processing technician pursuing your first specialty credential, a GI lab staff member formalizing years of hands-on experience, or a central service professional adding endoscopy to your scope of practice — this program meets you where you are and takes you where you're trying to go. The credential you're working toward signals something important to your employer, your patients, and your profession. I'd be honored to help you earn it. Let's get to work.
