Great format for learning content and very helpful with questions. Was able to get my 608 certification handled without issue.


I found the experience to be quite beneficial. The courses have a ton of in depth material that's presented in a user friendly way, i'm not sure there is a better option that is both epa certified and free available. kudos!

I found this site on the approved list of EPA testing site, the real draw for me was it was a way to study for and take, the EPA 608 test for free, can't beat that! I found the site easy to navigate and the training material was very good prep for 608 universal exam. The format made it easy to take and retake practice test and keep track of your progress to ensure you covered everything. Other than a few small errors in the material I can't fault the process at all. After a few days of self pace training I passed the 608 universal test with a score of 95%.

I can't believe this course was free. I was about to pay $375.00 for certification course when I discovered SkillCat. Highly recommend.

Studied for the EPA CAA Section 608 title II course and then took the exam - all online. Course was very good. Testing went smoothly. Was great to work at your own pace. SkillCat communicated well concerning the test. Highly recommended.

Richard Posadas

The EPA universal course offered by Skillcat is very comprehensive, well-structured, and easy to follow. Best of all, it's free. It helped me pass the exam flying colors on my first attempt. The online exam proctor, Nilima, was very accommodating and patiently assisted all examinees in accessing the test.

Thanks SkillCat!
