Certified Hemodialysis Technologist/Technician Exam

The Certified Hemodialysis Technologist/Technician (CHT) exam was designed by the Board of Nephrology Examiners Nursing and Technology (BONENT), to measure specific technical skills and proficiencies, along with general knowledge areas, for hemodialysis technologists and technicians. Many states require certification for hemodialysis technologists and technicians who perform patient care, so make sure to check with your state before applying to sit for the CHT exam.

What are the eligibility requirements to take the CHT exam?

In order to sit for the CHT exam, you must meet several criteria. All applicants must provide verification of their experience by submitting two letters of recommendation to BONENT. These letters must be from an immediate supervisor, who will also sign your application, and a mentor, peer, or other professional in the nephrology field. Both letters need to serve as character references and must include your full name, length of employment, and specific job-related duties.

  • If you are a technician, you will need to submit a copy of your high school transcript or official diploma; demonstrate at least 6 months of experience in the field of nephrology, including patient care; and be actively participating in an end-stage renal disease (ESRD) facility. If you are lacking experience in patient care, you can apply to take the exam within 2 years of completing a BONENT-approved educational program.
  • If you are a technician without a high school diploma, but with more than 4 years of dialysis work experience, BONENT will waive the requirement for a high school diploma or transcript.
  • If you are an LPN or LVN, you must have a current, valid LVN or LPN license; demonstrate at least 6 months of experience in nephrology; and be actively participating in an ESRD facility.

Please note that if you have ever been convicted of a felony, you will not be eligible for BONENT certification. Additionally, if you are currently unemployed but meet the aforementioned criteria, you will need to have your previous supervisor sign your application and write a letter of reference.
