How Our NATE Certification Training and Testing Process Works



We’ll walk you through 4 in-person classes designed by our seasoned NATE test prep instructor. Classes are 3 hours each and held once per week at our Nashville training center or streaming online



We’ll assign at-home reading to do between classes and work through sample tests during class, all designed to mimic the NATE test and give you strategies to help you pass the first time.



After your 4 prep classes, you’ll come back on week 5 and take the test at our offices while the material is still fresh on your mind.

*Note: NATE requires all testing to be done in-person. You may participate in streaming seminars, but you must travel to a testing site in order to take the test.

“I met Mitchell Saberon, my teacher in the second semester at Tennessee College of Applied Technology. The subjects were extremely hard, and he helped us make it easier plus he always tried to push us to by giving us the opportunity for hands-on field trips. I got my diploma and my license and started to work in HVAC field and any time I called to ask about anything, he always answer my question and helped me. I started to work as a technician then now I’m the Director of Engineering. And he is still helping me. I would like to say thanks Mitchell for all that he did.”

“I graduated from TCAT with my HVAC diploma. Mitchell Saberon was very qualified in class to teach HVAC. While sitting in class he was very aware and understanding when someone didn’t understand something. He helps keep everyone in the loop with what is being taught. Mitchell Saberon was one of the very few teachers that used visuals as he taught in class and that really helped with my learning.”
