Everyone was professional and respectful, and they also expect you to take the course seriously, which I think is a good thing. They provide all the materials you need, so you're never left guessing or feeling unprepared.

CER class FAQ

What is the CER?
CER stands for Certified Endoscope Reprocessor, a credential from HSPA (the Healthcare Sterile Processing Association) focused on reprocessing flexible endoscopes. ATS is an independent training provider and is not affiliated with HSPA.
Who is it for?
Sterile processing and endoscopy techs who reprocess scopes, or want to, and anyone adding an advanced credential on top of the CRCST.
Who can sit for the CER exam?
HSPA sets the exam eligibility requirements. Check HSPA's current CER requirements before you register for the exam, and ask us if you're unsure where you stand.
I already hold the CRCST. What changes when I add the CER?
HSPA requires 6 additional continuing-education credits per year for each additional certification you hold, on top of the 12 for the CRCST.
