What is a CCHT?
Certified clinical hemodialysis technicians are specialized professionals, also referred to as “dialysis technicians,” who are skilled in setting up and using a hemodialysis machine to administer dialysis therapy to patients.
By performing hemodialysis, hemodialysis technicians assist patients with end-stage renal disease or kidney failure. The dialysis machine removes metabolic waste from the patient’s blood, which is filtered and cleansed during this procedure before being returned to the body. In essence, the kidneys are responsible for this; however, when the kidneys aren’t functioning properly, a patient may need renal dialysis as a form of treatment.
Hemodialysis nurses keep an eye on the patient’s vital signs as well as the dialysis machines. They also provide support for any patient queries or concerns, educate patients about dialysis, and maintain the machinery and equipment used in the process.
Under the direction of a licensed nurse or doctor, hemodialysis technicians perform their work in hospitals, clinics, and dialysis facilities. The standard path to becoming a hemodialysis technician is to complete certified training after high school and get patient care experience.
CCHT Exam Eligibility
The CCHT accreditation is open to working dialysis technicians with a high school education or GED. You must also have completed a clinical hemodialysis technician training course that included both classroom teaching and supervised clinical treatment. To confirm the training program, you need to have the educator’s signature or present a certificate of completion.
If you have not yet been hired as a clinical hemodialysis technician, you must state how many hours you spent gaining hands-on patient care experience as part of your training program and the name of the facility where you did so. The facility manager or administrator must sign to confirm that the clinical, hands-on experience took place and was overseen by a registered nurse (RN).
You should have at least 1,000 hours or six months of clinical experience, but this is not a requirement.
If you have been out of work for more than 18 months, you must show documentation of current retraining and hands-on experience. The training must be verified by the RN educator’s signature, or by the signature of the facility’s administrator or manager.
CCHT Exam Outline
The CCHT exam contains 150 multiple-choice questions, 25 of which are unscored, and you will be given a time limit of 3 hours. The 25 unscored questions, known as “pilot” questions, are used by the test administrators to evaluate questions for future exams.
The questions are split into three cognitive levels: Knowledge (K), Comprehension (C), and Application (A).
- Knowledge (8%-13%): These questions are designed to gauge how well a technician can recall specific facts, common terms, fundamental ideas, and principles.
- Comprehension (23%-28%): These questions assess the depth of your understanding of a concept, going beyond simple recall.
- Application (63%-67%): These questions depict a work-related scenario and ask you the nature of an issue or the best course of action.
The exam is also split into 4 practice areas: Clinical, Technical, Environment, and Role Responsibilities. Each question on the exam will fall under one cognitive level and one practice area.
1. Clinical (71-78 questions)
The questions in this area cover various aspects of dialysis patient care before, during, and after treatment. Topics include using aseptic technique, evaluating and cannulating the patient’s access, monitoring the patient, and using an arteriovenous fistula to discontinue the patient’s treatment.
2. Technical (32-38 questions)
The questions in this area cover components of the extracorporeal circuit, water treatment principles, and how to deal with machine-related problems. Topics include monitoring the water treatment, mixing concentrates from powder, processing lab samples, and reporting an adverse event.
3. Environment (19-25 questions)
The questions in this area cover safety issues that may occur during dialysis treatment, such as infection control. Topics include using standard dialysis precautions, using proper body mechanics, disinfecting surfaces with chemicals, and maintaining an emergency exit path that is unobstructed.
4. Role Responsibilities (15-20 questions)
The questions in this area cover communication skills and the responsibilities of various roles within the dialysis facility. Topics include Maintaining appropriate relationships with patients and caregivers, effectively communicating treatment outcomes, using appropriate verbal and nonverbal communication with patients, and identifying the various roles and responsibilities of care-team members.

How the CCHT Exam is Scored
A group of technologists who are subject matter experts determines the passing score. The SME panel makes an evaluation of the standard necessary to find candidates with a sufficient degree of expertise and knowledge for the role. Therefore, the test results are evaluated against a predetermined benchmark.
Your score report will be provided to you at the end of the exam. To pass the CCHT exam, you must get 74% or more of your questions right.
If you pass the test, the report will include your results and let you know when your certificate will arrive in the mail and when your name will be listed in the NNCC Certified Directory.
In the event that you failed the test, the report will provide your grade as well as a breakdown of the test sections and the percentage of questions you correctly answered in each. You can identify the areas of the blueprint where you are weak and require more study by looking at this breakdown of subarea scores.
