NRA Rifle and Home Firearms Safety. Also a certified Range Safety Officer.
FBI certified (at the FBI Academy, Quantico, VA.) for Police Handgun, Rifle and Shotgun.
As for the NRA training, the course has to be conducted by an NRA certified Training Counselor, who is certified in that discipline. We have one in our club who is certified in everything except blackpowder and reloading.
The courses are usually about three days long and the cost will depend on the counselor and the overhead, such as where the class will be held, etc. There are costs involved and you can figure on a minimum of about $25 just for the training materials, such as books, binders, etc. The classes I've attended were all in the $75 range.
Hope this helps.
