CCHT Practice Test

Dialysis technicians are a vital group of individuals in any hospital setting. Many technicians find that continuing their education helps them help their patients by continuing to advance their knowledge and skills.

The CCHT exam (Certified Clinical Hemodialysis Technician) is a certification that is beneficial to all those in the field, as it validates their knowledge and expertise and furthers their career. Those who plan on taking the CCHT should consider a CCHT practice test an important step in preparing for the exam.

The CCHT Certification is administered by the NNCC, or Nephrology Nursing Certification Committee, and officially recognizes your expertise as a dialysis technician.

Just like any formal certification, it is meant to further your knowledge and show employers that you are committed, skilled, and informed about your role.

In order to be considered eligible to be CCHT certified, you must meet the following requirements:

  • High school diploma or equivalent
  • Completion of an approved training program (must include both classroom and clinical experience)
  • Have been employed as a dialysis technician in the last 18 months
  • Have completed at least 1,000 hours or 6 months of practice (preferred, but not required for certification)

The CCHT consists of 150 questions spanning three hours of allotted time. There are four main areas that the exam evaluates:

  • Clinical
  • Technical
  • Environmental
  • Role


The clinical portion of the exam tests your knowledge and understanding of patient care. The types of questions may be related to monitoring dialysis equipment, treating hypotension, discussing patient problems and events, and how to handle adverse reactions in patients.


The technical section consists of questions on water treatment and equipment-related issues. This includes using machinery safely, monitoring the water treatment system, correcting equipment failures, and ensuring quality control.


The environmental section deals with how you would handle an infection and other problems that can arise during dialysis. This includes questions on the Life Safety Code, following precautions, and disinfection.

Role and Responsibilities

This section goes beyond technical knowledge and will test your interpersonal skills. This includes maintaining patient privacy, professional boundaries, and training new technicians.

The CCHT-A is an advanced certification that is only available to dialysis technicians working at an advanced level. This includes a minimum of five years and 5,000 hours of advanced experience.

The CCHT is considered an entry-level credential for dialysis technicians. It’s recommended that you have at least six months (or 1,000 hours) of clinical experience before taking the CCHT.

If you’re studying for the CCHT test, then you’re likely already familiar with many of the practices and techniques necessary for a dialysis technician.

That being said, the test is meant to confirm your current knowledge and ensure you’re up to date on current practices and patient care. It’s important to review current information and familiarize yourself with exam materials.

  1. Make a plan

A study plan is essential for any exam. Break up the four sections into bite-sized pieces, making the information more digestible. If you try to study everything at once, you won’t retain the information as well.

Make sure your plan includes taking a CCHT practice exam – this will help you become more familiar with the exam.

  1. Use different materials

Diversity is key! Completing practice tests is an important step, and vital to familiarize yourself with the format and difficulty of the real exam. But it is also important to study with different types of materials to keep the information fresh, such as flashcards and videos.

  1. Be prepared

If you’re taking the exam in person, coming prepared on test day is going to ensure you can focus on the thing that matters: doing your best on the exam. Make sure you gather the necessary materials the night before the exam, including a government-issued photo ID, your nursing license, and an examination permit.

Can I take the CCHT exam more than once?

Yes. If you do not pass the CCHT exam and want to take it again, you may do so. You must re-apply and pay the full exam fee ($225) each time.

How many questions are on the CCHT exam?

There are a total of 150 questions on the CCHT.

Is CCHT the same as CCHT-A certification?

No. The CCHT-A is a separate exam for advanced dialysis technicians.
