I'll preface by saying that I am currently only a private pilot with aspirations of getting an instrument rating. No current plans to change careers, however I may also go for commercial and CFI in the future. That being said, I was recently looking into ground instructor ratings and was curious what sort of credability the aviation community would give a ground instructor that doesn't have commercial nor CFI ratings. More or less wondering if anyone would take me seriously enough to teach ground school. I'm always looking to challenge myself and if there was a chance to take on a bit of a ground instructor roll, that would be pretty cool. With an educational background and degree in Aeronautical Engineering, current job as a Mechanical Engineer, and about 4 years of mentoring/teaching experience (was a teaching assistant for a computer programming class 4 out of 5 years of my college career), I feel as if my experience is more than adequate to provide ground instruction; but whether or not anyone agrees is the more important question.
