First is find a school willing to fund it!!
Those are few and far between these days.
Maybe team with the kids club that will be feeding this program to do some fund and support raising.
IMO...
You got to have the support of the kids club to start a good program. Then to make it great it takes all 3 programs supporting each other.
It takes all 3 if you ask me.
There are some towns that do kids and HS and (again IMO) without a MS program they are behind other programs come HS time.
Good Luck to You!!!
Where are you looking to start one at?
