With regard to UTK, here is a link to the web page for NMF scholarships: Provost Scholarship - One Stop Student Services. For NMF status, there is an additional $2K/year (the Provost Scholarship) in addition to other merit scholarships that are awarded, such as the Volunteer Scholarship, here: Volunteer Scholarship - One Stop Student Services.
UTK does not give a full ride, or anything near it, for NMF status.
