I would have her look at joining a national guard unit as an MP or Medic. Have her stay at home and use that to pay for her local community college associates degree. If that is not enough to cover the cost of the degree, then use grants, scholarships and then loans to cover the balance.
After she has her 2 year degree, look into the ROTC program at a nearby state college. Some guard / reserve programs combined with ROTC can pay for the full ride.
Lastly, have her take a speed reading course and a typing course over the summer before she graduates high school. This will cut the high school and college work load in half.
We know a boy (man I should say!) who did just that— joined the national guard and became an MP. He finished his MP training last year and is now home going to school. I see positive changes in him, although still typical 20 year old in many respects.
