1.1 Current CER Exam Facts
Key Takeaways
- CER (Certified Endoscope Reprocessor) is issued by HSPA (Healthcare Sterile Processing Association), formerly IAHCSMM until its 2021 rebrand.
- The exam is 150 multiple-choice questions delivered in a 3-hour window at Prometric test centers.
- The exam fee is $140; CER renews annually with 6 endoscope-specific CE credits plus a $50 annual renewal fee.
- Scoring is criterion-referenced against a fixed passing standard, not curved, and there is no penalty for guessing.
1.1 Current CER Exam Facts
The CER (Certified Endoscope Reprocessor) credential is issued by HSPA (Healthcare Sterile Processing Association), the body formerly known as IAHCSMM (International Association of Healthcare Central Service Materiel Management) until its 2021 rebrand. CER recognizes a technician who can safely reprocess flexible endoscopes — a distinct, high-risk skill set separate from the general CRCST (Certified Registered Central Service Technician) credential.
Confirm every fact below against the official HSPA CER page and the current CER application before you pay, because policies and fees change.
The numbers you must know cold
| Fact | Current detail (2026) |
|---|---|
| Issuing body | HSPA (formerly IAHCSMM) |
| Questions | 150 multiple-choice, computer-based |
| Time limit | 3 hours |
| Exam fee | $140 (same as all HSPA exams) |
| Retake fee | $140 per attempt |
| Test vendor | Prometric (in-person test centers) |
| Eligibility | 3+ months hands-on endoscope reprocessing within the past 3 years |
| Recertification | Annual; 6 endoscope-specific CE credits + $50 renewal fee |
A fee note: the headline exam fee is $140. Older prep materials sometimes describe a fixed "$25 non-refundable processing portion" — treat the exact non-refundable amount and refund window as unverified and read them off the current HSPA application, not from memory.
Scoring you cannot game
Scoring is criterion-referenced, not curved against other candidates. HSPA sets a fixed passing standard derived from the exam blueprint, so you are measured against the content — not ranked against the people who tested the same day. HSPA does not publicly break out how many of the 150 items are unscored pretest items, so treat every question as if it counts. There is no penalty for guessing: never leave an item blank, even on the last numeric question you are unsure about.
Why CER is its own credential
Flexible endoscopes are the single most litigated device in sterile processing because they are heat-sensitive, lumened, and impossible to fully visualize internally. Outbreaks of carbapenem-resistant Enterobacteriaceae (CRE) traced to duodenoscopes pushed the FDA, CDC, and professional bodies to demand specialized competency — which is why CER exists alongside CRCST. CRCST is not a prerequisite; a technician can earn CER first, or hold it as a standalone credential.
How CER questions are built
CER is an applied workflow exam, not a vocabulary quiz. A typical item gives you a scenario — a scope with a failed leak test, a storage cabinet at the wrong humidity, a borescope finding of retained debris — and asks for the next correct action. Items are anchored to manufacturer IFU (Instructions for Use) and to consensus standards such as ANSI/AAMI ST91 (the flexible-endoscope processing standard) and the Spaulding classification. The right answer is the one that is both clinically safe and IFU/standard-compliant; the trap answer is the faster shortcut that skips a verification step.
The standards behind the questions
CER does not test opinion — it tests the published consensus standards and federal expectations that govern endoscope reprocessing. Knowing which authority backs an answer keeps you from picking a plausible-sounding shortcut.
| Authority | What it governs | Why CER tests it |
|---|---|---|
| Manufacturer IFU | Device-specific cleaning, contact times, brush sizes, compatible chemistries | The IFU is the legal floor; deviating from it is a citable failure |
| ANSI/AAMI ST91:2021 | Flexible and semi-rigid endoscope processing in health care facilities | The backbone reference for most processing-step items |
| Spaulding classification | Critical / semi-critical / non-critical device risk tiers | Decides whether HLD or sterilization is required |
| CDC / FDA guidance | Outbreak-driven duodenoscope and reprocessing alerts | Explains why drying, surveillance, and tracking matter |
| OSHA Bloodborne Pathogens Standard | PPE, exposure control, soiled-instrument transport | Drives decontamination-area and transport answers |
The current edition of the processing standard is ANSI/AAMI ST91:2021 (released March 2022). When the IFU and a general standard appear to conflict on the exam, the manufacturer IFU wins for that specific device — this is a favorite trap. ST91 itself directs you to follow the IFU.
Exam-day mechanics at Prometric
The CER exam is delivered in person at a Prometric test center. Arrive early with a valid, unexpired government-issued photo ID whose name matches your registration exactly. You will be assigned a workstation; phones, notes, and personal items go in a locker. The interface is standard multiple-choice with the ability to flag items for review and navigate back, so use a two-pass strategy: answer everything you know on pass one, flag the hard items, and return with remaining time. Because there is no guessing penalty, never end the exam with a blank.
Build an error log from day one
For every practice miss, write two sentences: "I missed this because …" (misread cue, didn't know the IFU rule, wrong sequence, overgeneralized) and "Next time I will look for …" (the specific cue). Group misses by the seven blueprint domains so you can see whether your weakness is reprocessing steps, microbiology, work-area design, or human factors — then steer study time toward the heaviest-weighted domain where you also score lowest.
What a pass actually means
Passing CER tells employers and surveyors that you can independently and safely carry an endoscope through the entire reprocessing cycle in compliance with IFU and ST91. The credential is increasingly required or preferred in GI labs, ambulatory surgery centers, and hospital endoscopy suites. Treat the exam as a proxy for the real job: the answers that keep patients safe are the answers that score.
