Certification 3

How to Prepare for the Examination

Those interested in becoming a Certified Registered Central Service Technician (CRCST) have a wealth of resources at their fingertips. IAHCSMM offers a host of educational tools to prepare technicians for their exam.

Please Note: Courses are preparation for the exam; passing a course does not equate to Certification. IAHCSMM's Education Department has developed materials as an optional method to assist individuals in preparing for the CRCST exam. Those materials were developed and produced independently of the Certification Council, which does not develop, require, approve, or endorse any specific training materials..

Preparation Options

To prepare for the CRCST certification, the following options are available:

  • Online Course: Purdue University offers an online course that is designed to help prepare Central Service professionals for the CRCST exam. You can find out more about the course by calling 800.830.0269 or by visiting Purdue's website
  • Distance Learning Course: Purdue University also offers a traditional correspondence course by mail that is designed to help prepare Central Service professionals for the CRCST exam. You can find out more about that course by calling 800.830.0269 or by visiting Purdue's website
  • Self Study: You may purchase reference materials and choose to study on your own to prepare for the CRCST exam. IAHCSMM's CS Technical Manual (8th ed.) was used as a reference in creating the exam, along with ANSI/AAMI's ST79 (2017 ed.), and AORN's Perioperative Standards and Recommended Practices (2018 ed.). You can order these publications through the IAHCSMM store and the AORN 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.

CRCST certification requires that you pass the certification exam and complete 400 hours of hands-on experience in a CS department. These hours can be completed before testing or within 6 months of passing the exam. IAHCSMM highly recommends completing, or at least beginning, your hours of experience before testing. Hands-on experience provides an invaluable resource with which to better understand the standards, knowledge, and practices needed to be successful in a CS department and on the CRCST Exam. More information on the accumulation of these hours can be found under the Requirements section.
