What Our students have to say

After taking your class three weeks ago and studying with the practice questions I passed both the business and plumbing portions on the first attempt.

I will be looking to take the specialty electric course you offer in the near future. Your class was a positive experience and I will be recommending it to others.

Mr. Pratl,

I wanted to reach out and express my gratitude for the service you provide. I have taken your HVAC license prep class during the spring and I challenged all 3 licensing exams and the business law exam during the month of September with great success.

All of the exams were passed on the 1st attempt and I do not believe that would not have happened without me implementing your strategy to pass. I have several coworkers interested in pursuing their licensing so I am passing along your information to everyone that asks.

I truly feel that your class was worth every penny spent.  Thank you again!!

Hey Michael, just wanted to let you know that I passed my P-1 exam yesterday. Thank you for your study guide that was exactly on point. The technique you teach is the way to go for sure. I would recommend it to anyone. I have used your class now to take 4 exams (H-3,H-2,H-1, and P-1) and have passed them all the first time. Probably will take your class for the electrical exam coming up in the future. Thanks again for the help!

I extend my appreciation to The Technical Training Institute. I have passed the Business Law as well as H2 and H3 . Your method of teaching proved very much worth the time and money I spent.  I really appreciated the fact that I had a question during my studies in the last few hours . I emailed you and got a simple prompt explanation and, I passed!

I would highly recommend you guys and will do my continuing education with you.

Good Morning Mike, Just wanted to drop a line and say thanks. After taking your Heating Exam Prep course August 14 &15 and studying with your methodology, techniques and material I was able to pass the H-2 license exam on August 31st. Your information was challenging and your advice was right on. I will be taking the H-3 Class 1 Exam within the next few months.  Thanks for your help,

Your advice worked! I was nervous about taking all three of my exams within a two week period but it was the best thing that i could do. Your material helped me out a lot. I was able to pass my H-3, H-2 and H-1. Thanks for all of the help. I will absolutely recommend your class to anybody that is trying to get their license. Almost forgot to tell you thanks on the SP-PH Electrical License too, your class helped me pass that exam.
