The NRA has 'turnkey'
programs already set up to give your efforts form and function, complete with achievement awards and scholarships, as well as financial support and design assistance for range construction/improvements.
They also have
programs to give you the skills needed for instruction, and training aids for your students..
Play your cards right, and the fees and such involved could become reimbursable course expenses.
Every school sport and extracurricular program should have a Booster Association to aid in promotion and help defray costs to the program and the school (but not to have say in what the program is or how it does its things). It helps keep your program from getting buried under the others, like football, basketball, baseball, etc.
Make certain your boosters do not get buried among competing programs in a blanket sports association; keep yours separate, and do not allow boosters to push their own/individual agendas. All booster activities should be kept aligned with the whole program. Boosters can be delegated to serve as reps to outside organizations like those below. You do not need to run the boosters; and do not allow anyone to make your position reportable to the booster association, you have to work at the pleasure of the educational institution.
Back in the 1960's, when I was in High School, Marksmanship was a School Team Sport, the Team was a CMP/DCM as well as state rifle/Pistol association affiliated club, and I earned my Letter in it for two years running.
The CMP runs competition
programs for youth, as well as
some support for firearms, ammunition, and other necessities.
You already have a lot of the hard part behind you, with a willing school leadership, and some supporting facilities. Be certain to establish/maintain a good rapport with the School Board (i.e., reports at meetings, etc., including reciprocal promotional support for school board candidates who favor marksmanship education.), and provide demos for involved parents and school leadership (
NOT open to the public). If not already a fact, establish a relationship with local range Clubs. This is all a necessary self-support issue, and a key to preventing sudden hostile turns of opinion among those you depend upon for your program's existence.
