Reputation is earned not given.
What can I do to show I am a reputable instuctor?
:help:
As an Instructor and in my humble opinion, you earn your reputation by, of course, ALWAYS showing up for class and then delivering a courteous, well planned and well practiced program. Conscientiously meet all the National, State and Local requirements for the specific course you may be teaching at the time. Professionals are professionals because they execute all that is promised, all that is required, all that is expected and then they exceed what the students expected by a wide margin.
To be regarded as a professional you must be able to exceed the common man's expectations on every front. You must dress professionally (appropriate but sharply styled, clean, professionally pressed clothes; well groomed hair-beard-mustache; clean, trimmed nails; polished shoes or boots, etc.), present your product in a professional environment (clean, comfortable, well lit, good acoustics; bright, readable display screens; neat, clear, well designed course books and handouts) and provide an appropriate, safe and, if possible, spacious range for live fire activities. You must speak clearly, authoritatively and with as little gun-slinger slang as possible, i.e., avoid all the abbreviations we commonly use when talking with our peers. Cuss words and/or off-color stories are strictly off limits.
The above will create a professional impression in the minds of your students but that is only the front half of the battle. The second is to get your students to give you their impressions via comment sheets and then use those quotes as testimonials. You can say that you're the greatest thing since sliced bread but few will believe it. But if you post 5 and then 10 and then 50 high-praise comments in the form of direct quotes from students ("Best handgun instructor I ever had", John Brown, Anytown, USA), associates and vendors then you will have achieved the desired end.
Hope that helps,
