The Certified Hemodialysis Technologist/Technician (CHT)
exam has been developed and maintained by BONENT (Board of Nephrology Examiners
Nursing Technology) as a way to ensure that all dialysis nurses and technicians
are certified according to national standards. This exam is meant to assess a
certain set of skills and knowledge in accordance with the technical
proficiency needed for the industry and field of work.
Who is Eligible?
All those seeking certification as a CHT must meet the following requirements:
- Have a high school diploma or official transcript with your principal’s signature and/or the school seal
- Have at least 6 months of experience in nephrology patient care
- Have current active participation in an ESRD facility
If you do not have the required experience, your application will still be considered if you have completed a BONENT approved program within the last two years.
It is also important to note that many state licensing agencies may impose other requirements or prerequisites for candidates wanting CHT licensure. Please make sure to find out what these are well ahead of your exam.
Finally, if you have no proof of high school graduation but have worked in dialysis for for more than 4 years, you can waive the high school diploma requirement.
