Where rules vary
One uniform exam worldwide, grounded in the U.S. CMS certification mandate for dialysis patient care technicians but administered internationally — the handbook states examinations are conducted throughout the United States and in a growing list of other countries (Australia, New Zealand, Singapore, India named), with over 900 CBT testing locations worldwide and BONENT certification accepted in all U.S. states
Eligibility
High school diploma or official transcript PLUS a minimum of 6 months of experience in nephrology patient care PLUS current active participation in an ESRD facility; applicants without patient-care technician experience may apply within 2 years of completing a BONENT Approved Training Program; experience must be verified by two signed and dated reference letters (the diploma requirement is waived after 4+ years of dialysis experience)
Retake policy
A candidate who fails may retake the next available examination by submitting a signed application (or retake request form) with a copy of the most recent score report and paying the exam fee again; a maximum of three attempts is allowed within 12 months, after which 8 hours of nephrology-related continuing education must be completed and documented before any further attempt
