I was reviewing the national scholars program web site, and may have missed a distinction earlier.
https://scholarships.tamu.edu/scholarship-programs/national-scholars#0-NationalMeritScholars
According to that page:
NMSF receive
a) President’s Endowed Scholarship valued at $3,000 x 4
b) Study abroad stipend valued at $1,000 x 1
Semifinalists who are named National Merit Finalists are guaranteed additional award opportunities:
a) National Merit Recognition Award valued at $7,000 x 4
b) National Merit Sponsorship valued at $500 x 4
c) National Merit Recognition Award Supplemental Scholarship $3,000 x 1
Originally, I read this as an either / or. Now it seems clear they are cumulative.
I will go ahead and email later this week for a definite answer, but was curious if anyone else already had confirmation that they are cumulative.
