Cathy1911, Chris and all, no prerequisites for RSO except for being a safe experienced shooter. CRSO will require about 6 hours of pre course at home study. I'll need to get materials to CRSO candidates as soon as I receive them from the NRA. Keep in touch Wes or with me by pm or post here with questions. It'll be a long day but a productive, valuable and fun one. Anytime you can spend time with fine like minded folks, it's a good day. There will be one written test for RSO and three for CRSO.
By the way, I've conducted 2 NRA Certified Pistol Instructor courses in the last three weeks and all candidates were successful. So there will be 10 new Certified Pistol Instructors around and about the area soon as the NRA processes the paperwork.
Thanks and take care.
