As of 10 years ago when I was there, they offered a full ride to anyone that can prove 1/8 blood. And there was no limit to the programs. It was a result of the Penobscot Land Claims agreement in the 70s.
As a matter of fact, the only person that I know that graduated as a result of the program was in Electrical Engineering.
Unfortunately, I knew a lot more kids that came in on the program and partied their way off the campus. Let me state strongly that I think that this is more a function of immature 17 and 18 year olds with nothing at stake in their education, than any racial commentary of any sort.
I didn't get to be where I am in life by latching on to the pity of America-hating leftists, and when I examine the circumstances of my kinsmen who have latched on to it, I can only shake my head in sorrow.
