I found the online Hazwoper Refresher to be convenient.  The updated test was comprehensive and easy to follow.  Thank you for the convenient service you provide.

My work was offering a fall protection class on a Saturday on our own time.  I found your website and was very pleased with the test and certification.  Turned in the certification to our government contractor and was accepted without hesitation!

I found this course to be very beneficial.  It was clear, easy to follow along, and I learned a lot.
