The IBEP (International Bowhunter Education Program) was designed and is administered by the NBEF (National Bowhunter Education Foundation).
I think presenting bowhunter education is one of the best ways a bowhunter can pass it on -- 2nd to mentoring of course. There is a lot of very specific material to cover but the course was designed by very avid bowhunters. I always have a terrific time teaching the course and usually pick up something from folks in the class about scouting, equipment, etc. I certainly learn a lot about why some people bowhunt.
The best bowhunter ed instructors are very good at teaching. They stay on schedule, cover all the material, use appropriate and diverse visual aids, and are friendly and open-minded. Of course when the instructor is also an experienced bowhunter from which to draw examples, that is even better. No matter how great a bowhunter is, if they don't have a knack for teaching, they should use their talents helping.
The best classes will have more than one instructor. By teaming with others the course is often more interesting. NBEF has many useful visual aids. Instructors should incorporate many hands-on exercises to make the course interesting.
A bowhunter education instructor should have high integrity. People in the class expect you to be one of the top-notch examples of what a bowhunter is; knowledgable, ethical, law-abiding, and eager to pass it on.
I've been an instructor since 1991 and am a current board member of NBEF.
