BONENT Certification Exams

The Board of Nephrology Examiners Nursing and Technology is an organization that is recognized by the National Association of Nephrology Technicians (NANT). BONENT began offering exams to technicians in the early 1970s as an alternative to those being offered through the American Society of Extracorporeal Technology (AMSECT). Its members work to review and revise exams so that they reflect current standards and to ensure that one’s competency is accurately evaluated.


BONENT examinations are administered in many parts of the World including the United States, Singapore, Australia, Turkey, and New Zealand. The first examination offered through BONENT was the Certified Hemodialysis Technician (CHT) which remains the core credential offered to individuals working in the industry. Two additional exams including the Certified Hemodialysis Nurse (CHN) and the Certified Peritoneal Dialysis Nurse (CPDN) were added in later years. BONENT continues to depend heavily on its members for financial and administrative support.

Recommended Reading Materials


There are a few textbooks that have been endorsed by BONENT for studying purposes. While applicants are not required to review these materials, those who do study tend to perform better. It is also recommended that a technician consult with other technicians and facility administrators in order to get a better idea of what can be expected and how to prepare for the exam.
