Certified Endoscope Reprocessor (CER)

In recent years, few areas of sterile processing have seen such rapid, and necessary, change as endoscope reprocessing. To help ensure that endoscope reprocessing professionals have the knowledge and skills necessary to handle this rapidly evolving specialty, IAHCSMM has developed the Certified Endoscope Reprocessor (CER) exam.

Certified Endoscope Reprocessor (CER) certification is designed to recognize individuals who have demonstrated the knowledge and skills necessary to pre-clean, test, decontaminate, inspect, disinfect and/or sterilize, transport, and store endoscopes in accordance with industry standards, guidelines and regulations, and manufacturers’ instructions for use. CERs are crucial members of the healthcare team who are responsible for endoscope preparation, which is critical for patient safety in a healthcare facility.

To earn CER certification, candidates are required to successfully demonstrate skills through completion of hands-on work experience as well as successful completion of an examination developed to measure the understanding of endoscope care and handling and infection prevention. CER certificants are required to recertify annually through completion of continuing education requirements.

How to Prepare for the Examination

Those interested in becoming a Certified Endoscope Reprocessor (CER) can prepare in one of the following ways:

Self Study: You may purchase reference materials and choose to study on your own to prepare for the CER exam. IAHCSMM’s Endoscope Reprocessing Manual (1st ed.) was used as a reference in creating the CER exam, along with ANSI/AAMI’s ST91 (2015 ed.), and the following articles by the Society of Gastroenterology Nurses and Associates (SGNA): Standard of Infection Prevention in the Gastroenterology Setting (2019), and Standards for Infection Prevention in Reprocessing Flexible Gastrointestinal Endoscopes (2018).
You can order the IAHCSMM and ANSI/AAMI publications through the IAHCSMM store and download the above articles from the SGNA website.

Work Experience: You may take the exam based on your personal knowledge from experience in the field; it is not required that you take or pass a preparatory course, nor study materials on your own. Applicants can apply directly to take the exam without purchasing study materials or enrolling in a course.
CER certification also requires the completion of three months of hands-on experience reprocessing endoscopes prior to testing. Because of the complex nature of endoscopes, firsthand experience is essential to supplement an individual’s understanding of the concepts, knowledge, and standards necessary to be successful reprocessing endoscopes and on the CER Exam.

Please Note: IAHCSMM’s education department developed some of the materials referenced above as an optional method to assist individuals in preparing for the CER exam. They were developed and produced independently from the Certification Council, which does not develop, require, approve, or endorse any specific training materials. Online/distance learning courses are not available for the CER.

Content & Composition of the Examination
The CER exam will test your proficiency in these areas:

  • Microbiology and Infection Control
  • Endoscope Purpose, Design, and Structure
  • Work Area Design
  • Endoscope Reprocessing Steps
  • Endoscope Handling, Transport, and Storage
  • Endoscope Tracking, Repair, and System Maintenance
  • Human Factors That Impact Endoscope SystemsEach of these seven knowledge domains outline the type and amount of content covered in each section, as well as its weight on the certification exam. Please click here to see the full CER Exam Content Outline.
Requirements for the Examination

As well as passing the certification exam, three months of hands-on experience are required in order to obtain CER status. Because of the complex nature of endoscopes, firsthand experience is essential to supplement an individual’s understanding of the necessary knowledge and concepts of reprocessing, and to illustrate their practical use. This experience must include the pre-cleaning, testing, decontaminating, inspecting, disinfecting and/or sterilizing, transporting, and storing of endoscopes.

Provisional testing is not available for CER examinations. All experience must be completed in full before applying to take the exam. Hours must have been accumulated within the past three years.

The exam is computer based and no writing instruments are needed (a paper and pencil version of the exam is not available.) The test is comprised of 150 multiple choice questions and you will have 3 hours in which to complete the exam. Questions can be marked for review and answered or changed later in the exam. A 15 minute tutorial describing how to take the exam on the computer precedes the test and is also available online, here. For more information regarding the testing process please see the Certification Testing section.
