This overview includes information to help you prepare for the Certified Clinical Hemodialysis Technician, or CCHT, exam. You’ll find details about eligibility, the test format, registration, costs, test-day expectations, scoring, retakes, and study resources.
Exam Background and Purpose
The CCHT exam is offered by the Nephrology Nursing Certification Commission, or NNCC. It is designed for clinical hemodialysis technicians who provide direct care to patients receiving hemodialysis treatment.
The exam measures whether candidates have the knowledge and skills needed to work safely and effectively in a dialysis setting. Certification is commonly required for dialysis technicians, and candidates should review current federal, state, employer, and NNCC requirements before applying.
Test Overview
The CCHT exam contains 150 multiple-choice questions, and the time limit is 3 hours. The exam may be offered in computer-based or paper-based formats, depending on the current testing options available.
The exam covers four main areas of dialysis practice:
- Clinical (50% of the exam) — This area covers patient care before, during, and after hemodialysis treatment. Topics may include patient monitoring, treatment setup, complications, vital signs, documentation, and responding appropriately to patient needs.
- Technical (23% of the exam) — This area covers dialysis equipment, water treatment, machine operation, alarms, troubleshooting, dialyzer use, and technical procedures related to safe treatment delivery.
- Environmental (15% of the exam) — This area covers infection control, safety procedures, chemical handling, body mechanics, emergency response, and maintaining a safe dialysis environment.
- Role Responsibilities (12% of the exam) — This area covers communication, confidentiality, professional behavior, patient interaction, teamwork, and understanding the responsibilities of the hemodialysis technician within the care team.
Eligibility Requirements
Before applying for the CCHT exam, candidates must meet NNCC eligibility requirements. These typically include education, dialysis technician training, and clinical experience requirements.
Candidates may need a high school diploma or equivalent, completion of an approved or qualifying training program, and recent work experience or hands-on experience as a clinical hemodialysis technician. Eligibility rules can change, so candidates should check the current NNCC requirements before submitting an application.
Costs and Payment Options
CCHT exam fees, application fees, retest fees, and payment options can change. Candidates should review the current NNCC application instructions before applying so they know the exact cost, accepted payment methods, refund rules, and any deadlines that apply.
Registration/Times/Locations
Candidates must apply through the official NNCC certification process and receive authorization before scheduling the exam. During the application process, candidates submit required eligibility information, documentation, and payment.
Once approved, candidates receive instructions for scheduling the exam. Testing options, locations, appointment availability, permit windows, and testing formats can change, so candidates should follow the instructions provided with their current authorization materials.
Test Scores
The CCHT exam is scored based on the number of correct answers. The raw score is converted into a reported score, and candidates receive information about whether they passed.
The current StudyGuideZone page lists 74% as the passing score, but candidates should confirm the current passing standard directly with NNCC before testing, since scoring policies can change.
Retaking the CCHT Exam
Candidates who do not pass may be allowed to retake the exam according to NNCC retake policies. Retake rules may include waiting periods, new application steps, and additional fees.
Before applying again, candidates should review their score information, identify weaker content areas, and confirm the current retake process.
What Should I Expect on Test Day?
On test day, follow the instructions provided by NNCC and the testing center. In general, you should be prepared to:
- Bring the required authorization materials and identification.
- Arrive early or log in before the scheduled appointment time.
- Follow all check-in and security procedures.
- Store or leave behind prohibited personal items.
- Use only materials allowed by the testing rules.
- Manage your time carefully across the 3-hour exam.
- Answer every question, since unanswered questions can hurt your score.
Personal items such as phones, bags, notes, study materials, and electronic devices are typically restricted in the testing room. Candidates should review their appointment instructions before test day so they know exactly what is allowed.
How Can I Prepare for the CCHT Exam?
Start by reviewing the four major exam areas: Clinical, Technical, Environmental, and Role Responsibilities. Clinical care is the largest section, so make sure you understand patient monitoring, treatment procedures, complications, documentation, and safety steps before moving on.
Then review technical and safety topics, including dialysis equipment, water treatment, alarms, infection control, emergency procedures, chemical safety, and communication with patients and staff.
Practice questions are useful because they help you apply dialysis knowledge the way it may appear on the exam. After each practice session, review missed questions carefully so you understand the patient-care rule, technical process, safety procedure, or professional responsibility behind the correct answer.
