I highly recommend these courses

I am officially a Commercial Combination Inspector! Thank you so much for these courses. Having the confidence that I knew the information made taking these tests so much easier. I highly recommend these courses to every inspector I know looking to obtain a new certification. Thank you again for all the help your team has provided during these courses!

Extremely helpful tool

I found the SI Certs Program an extremely helpful tool in obtaining my ICC B2 Commercial Building Inspector Certification. Completing the coursework and practice exams gave me the confidence I needed to pass this difficult exam.

I completed the Commercial Building Inspector course and also passed my ICC exam today. It was a nightmare and I couldn’t have done it without your program and Tom’s coaching help! I think Fireproofing is next.

Good morning, Gabe.

Thx in advance.

Their customer support is unbelievable!

This app is perfect and their customer support is unbelievable! All I had to do was follow the class, step by step, and I passed all 3 tests (first try) to become a reinforced concrete inspector. I was extremely nervous about the plans-reading test, but I passed that as well.

I was especially impressed with how helpful these guys are when I had questions. They always respond within a day or two and answer all my questions, even after my paid class had ended. I am now taking their masonry class and so far it is equally impressive. I highly recommend these classes.

With our C5 Commercial Combination Inspector Training Package, you will only do one course at a time before starting another. You do not need to purchase/acquire all books for the four courses up front, and you can do them in any order. Get only the books you need for first course. Even check your local library. Then before you start the next course, acquire the next course references. This will reduce your cost impacts along the way.
