Current CCHT Certificants, NNCCs FailSafe policy protects you. If you take, but do not pass the CCHT-A examination, NNCC will grant recertification of your CCHT credential automatically.

Three Easy Steps to Certification

  • Five (5) years of continuous employment and a minimum of 5,000 hours as a clinical dialysis technician.
  • 30 contact hours of continuing education relevant to the practice of a hemodialysis technician, within the previous three years.
    It is recommended but not required that continuing education be approved by one of the following:
    • Organizations accredited by the American Nurses' Credentialing Center — Commission on Accreditation (ANCC-COA), the credentialing body of the American Nurses Association.
    • The American Association of Critical-Care Nurses (AACN).
    • The Council of Continuing Education.
    • All State Boards of Nursing.
      • For example: The National Association of Nephrology Technicians/Technologists, which is an approved provider through the California State Board of Nursing.
      • If you are a Preceptor for dialysis technicians, you may use preceptor hours towards your continuing education requirement. A maximum credit of 8-contact hour can be applied to 160 precepting hours within the 3-years prior to applying to take the exam.

  • Caution: Test preparation websites offering alternative and/or shortcuts to test preparation should be avoided. Exam content is confidential and is not shared with any individuals involved in test preparation activities. "Tricks of testing" and "short cut methods for test preparation" are specifically avoided when creating this exam. We test candidates on content and not on their "test taking skills." If you have any questions about the best methods to prepare please call us at 888.884.6622. Our goal is that each exam candidate best use their time and money to reach the end result of demonstrating their excellence in nephrology patient care through certification.

The purpose of the CCHT-A Practice Test is to allow candidates for the CCHT-A examination to practice with a test similar in content and format to the actual CCHT-A examination. However, no questions on the CCHT-A Practice Test will be on the actual CCHT examination. Taking the CCHT-A Practice Test is not required and does not guarantee a similar result on the CCHT-A examination.

The fee for the test is $30. The CCHT-A Practice Test contains 50 multiple-choice questions available in two modes: Practice Mode provides the correct answer and rationale after each question, while Test Mode holds the results until the end of the test. Both modes at the end of the test provide a Score Report which displays your score and breakdown of percentage correct in each area of the test blueprint. Please note: NNCC will now offer the online practice exam for free to individuals who have been approved for the CCHT-A certification examination.

You will have access to the test for 90 days. Several scrambled versions of the same 50 questions are offered for retesting. Your credit card payment will be processed on-line, and you will be granted immediate access to the CCHT-A Practice Test.

Emotional Preparation

  • Moderate anxiety is normal and may be helpful - you may be more alert and open to learning; however too much anxiety is detrimental and will interfere with learning and test-taking.
  • Study and prepare for the examination so that you feel confident.
  • Think positively - you possess a wealth of experience and the examination will allow you to demonstrate that knowledge.
  • Use anxiety-reducing strategies:
    • relaxation response.
    • guided imagery.
    • exercise.
    • prayer.
  • Even though some test takers may finish the exam early, use as much of the allotted time as you need to think through and answer the questions.

Physical Preparation

  • Get a good night's sleep.
  • Eat before the examination - those gray cells will have glucose available when you're answering questions.
  • Gather all the materials you need to take the test the night before the exam:
    • government-issued photo ID.
    • nursing license.
    • examination permit.
    • sweater or jacket in case the room is cool.
  • Allow plenty of time to arrive early.
  • If you are distracted by other candidates during the test or leaving to use the rest room, select a seat at the front of the room where you will be less likely to notice the other candidates.

Tips on Answering Examination Questions

  • Read the questions carefully and focus on key words in the question such as "first", "most likely", "most important", "best". These words are usually printed in boldface type to attract your attention.
  • As you read the question, anticipate the correct answer.
  • Read each of the four choices carefully. Even if the first option sounds correct, read all options before choosing the answer.
  • Do not "read into" the question. Answer the question based only on the information presented, even if you think the answer is too obvious or too easy.
  • Do not be afraid to change an answer. Research has shown that more often than not, test takers change answers to the correct one.
  • Do not spend too much time on any one question. Make a note of the questions of which you are uncertain and return to them later if you have time.
  • If you are unsure about one of the content areas, you may find it helpful to complete the other areas first and leave the problem area for last.
