Drug tests and background checks huh? Like the instructor above i have to ask 2 things who will pay for it and who will oversee it. If PADI requires it will NAUI and everyone else follow? There are literally tens of thousands of instructors. Here in the states and in other countries. If i move to the Carribean and teach do they do a background check only there or do they check here too? I am the father of 7 great kids and i will certify them myself, but were that not the case I would sit in on EVERY second of EVERY class. What kind of irresponsible parent puts their kids in a class that could kill them (if the instructor is on drugs as we are surmising here) and then just walks away? If you have ANY doubt find a new instructor. If you think he`s a pedophile or are just concerned, then you can run his name yourself and find out...as long as he`s been arrested. If not....watch your own kid and be safe!
