Certified Hemodialysis Technologist/Technician (CHT) Exam

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.

There are two forms of this exam: paper or computer-based. The paper version of the exam costs $220, while the computer-administered exam charges $250. Separate applications exist for each.

When and Where is it Taken?

If you choose to take the exam via paper and pencil (PPE), you will find a list of available testing sessions at select locations and dates throughout the year.

The computer-based test (CBT) is offered at a number of locations throughout the U.S year-round. Once your CBT application has been approved. You will be given a username and password to use for the scheduling process. This will allow you to choose a location, date, and time that is most convenient for you.

It is recommended that you choose your exam session quickly, as CBT locations fill the available space on a first come, first served basis. It is also important to note that your CBT approval is only good for 6 months. If you do not schedule and take your exam in that time period, you will have re-register and pay another fee.

What Can I Bring?

Once you have scheduled your exam, either PPE or CBT, you will receive a confirmation letter listing the address of your testing location. This letter must be brought to the testing location with you at the time listed on your letter.

This time listed will be before the actual beginning of the exam to allow for you to check-in to the facility and be seated. Those who arrive late will not be allowed to test that day and will need to re-register and pay a new fee.

You will need to bring at least one photo ID. A current and valid driver’s license, passport, government-issued ID, or notarized photo with your name printed on the back are the only acceptable forms of ID.

No personal belongings are to be brought into the testing center with you, including pencils, study materials, and calculators. Pencils will be provided for you. If anything but your ID is brought with, you will be dismissed and your scores voided.

How Can I Prepare for the CHT Exam?

That’s a great question.  We’ve broken down the answer into three parts.

  1. Do yourself a favor and study.  Do not walk in unprepared. We have recommended prep materials below, but that only helps if you actually try.  Plus, studying is actually proven to be the best antidote to test anxiety.
  2. Take care of yourself.  Make sure you’re eating well, exercising, and sleeping.  All of these things are scientifically linked to brain performance.  If you take care of your body, you’ll be helping your grades.
  3. Get a study guide or set of flashcards.  Some people study better a certain way. Find your study strengths and make the most of them.  We’ve tried to make it easy for you by tracking down the best study guide and flashcard set for your exam. Below you’ll see links to both!
