National Guard
mwbluebeard,
In response to your question; it depends on the state and college. Here in Massachusetts, students get "free tuition" to any public college (like my college) if they join the Guard.
I recommend that you check with each individual college to see what their policies are.
I also very much encourage you to understand that the Guard pays TUITION. I have had several families over the years think that the Guard was paying for their full educational costs.
I am a strong supporter of the Guard - however, it is very important that a student check out all of the pros/cons before signing a Guard contract.
Feel free to contact me if you have questions.
