Hi,
Yes it does help. But it depends on where you are and what you are trying to do as an instructor. Any documented training you do helps build on experience as an instructor. Each range, CFO, province, police academy has a way of looking at things, so it is varied as to what is recognized. You have to remember that the N.R.A. is the oldest recognized and organiized organization in North America for training standards, that are copied by most other groups. Continue to gain as much experience and training as you can towards your goal. Remember to always be a student first, as what you learn can always help you be a better instructor and be passed on to your students. Good luck.
