FYI I just received the response below from the ISP regarding updating NRA instructor certification renewals. I had emailed a question about updating my certificate to Instructor_Docs@isp.state.il.us which produced this response today from ISP. So I guess we can either send by snail mail to the address below or email to the address above. Mr. , Yes, we do require you to keep your NRA instructor certification current in order to remain a valid ISP Firearms Concealed Carry Instructor. Please forward the updates to this address as they are expiring. We have updated your instructor profile. Thank you for the information.
