The Amigo scholarship is part of OOS National Scholars award. You can’t separate the two. The Amigo reduces the tuition rate to in-state rates then the National Honor award covers instate tuition, plus room & board. ( $18,868 is the value of the National Honors schollie for instate students.)
So if your child receives the National Honors Scholarship, he will automatically receive the Amigo Scholarship also.
Not 100% certain, but I believe the number of NMF awards may be limited.
I do know the number of Amigo Scholarships is limited and that not everyone who applies for the Amigo receives it.
