Studying for the CCHT Exam

If you are 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 are 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.

2. 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.

3. 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.
