Is there a shortage of local instructors,(Greater Dayton area)  I am very interested in becoming an instructor. i have extensive military fire arms training including USMC range saftey officer, but nothing civilian. what i would like to know from Ohio instructors is, what classes do I need to take and where can I take them. I am already planning on taking some NRA classes (range safety and other related classes) but I would like to get qualified to teach.
Thanks in advance for any advice.

You need to attend a NRA instructors class given by an NRA training counselor in your desired discipline.

You can look on the NRA website to search for one in your area by zip code. I attended mine earlier this year and the cost for handgun was around $250'ish if I remember correctly. It not bad at all and you will be required to pass the written and firing portion of the instructors course to be a certified instructor. Once you pass you will wait to receive your instructor certification. After you receive it you can then teach the Ohio CHL course.

Also you can take the NRA Range Safety Officer course at home and test out for the NRA RSO once you pass the certified instructors course if you desire that certification as well. Its easy and I did mine rather than attending another class somewhere else.

As Chuck said there is no bonus points for LE or military but the training counselor will likely want to make sure you have a knowledgeable firearms background to be an instructor.
