The Posse Scholarship is a full-tuition Scholarship. Anyone has any insight as to the availability or possibility of having scholarships awarded to cover/assist with room & board from the Posse school in which the student is selected?
That would usually depend entirely on the college itself. Some Posse Partner colleges which are full-need colleges (like Vanderbilt) are more likely to do so, while places like U Wisconsin are probably less likely to do so.
If you (or your kid) becomes a semi-finalists, that is something that you should ask the college with which they (or you) are paired.
