I believe in the near future we will see the focus on instructors and not the course. I believe Massachusetts is in the process of setting up Minimum Training Curriculum Parameters, similar to , Utah does it. The instructor will give "a" course, certifying that all parameters have been met. Instructors with those with a NTO Certification, i.e. NRA, USCCA, SAFTD or others with established instructor certification programs.
In a discussion with the MA SP, I've been told changes are a few months away.
This is just my opinion based on discussions with several parties. Connecticut has gone from pretty much only NRA BP to looking at the individual instructors and their credentials, along with individual lesson plans being considered. USCCA submitted and approved by a few CT Instructors.
