Some programs offer state approved diplomas, such as Revere.
There’s the recently re-named Paris Junior College program in Paris,
Also, you could attend Arrowmont School of Arts and Crafts in
Gaitinburg, TN, there some classes can be taken for credit through
the U of TN. (there is an extra fee for this)
Other schools such as Pennland, Haystack may also have relationships
with colleges, but I only know for sure about Arrowmont.
