Most colleges and universities have literaly hundreds of scholarships available to students. Many successful students accumulate two,three or more methods of funding. I am not aware of any designated martial arts/taekwondo/karate scholarships. We have had a martial arts program cognate in Exercise,Sport and Health Education at Radford University (www.radford.edu) since
1986. Best advice is to begin early and collect info on as many scholarship/funding programs as possible. Good Luck.
