National Hispanic Recognition Program Cutoff

I’m wondering if anyone has ever heard of what is happening with my son. My son scored a 196 on the PSAT in TX in Oct 2014. He marked hispanic on the PSAT form but he did not receive an invitation to apply to NHRP, so he self-nominated in May 2015. He received notification in Jul 2015 that he received the award. He was not on the list of recipients received by his high school from the College Board. I notified his HS that he self-nominated, sent them his notification letter and certificate and they also received independent acknowledgement from the College Board that he received the honor. His HS will not acknowledge the honor in any school award ceremony or publicity because CB will not put him on the official school list of recipients. He is on a self-nominee list. He has attended this HS all four years and took the qualifying PSAT there. This matters because this award is considered an advanced measure towards a distinguished diploma and they refuse to count it. Am I wrong to be angry with the school? Or is this the college board’s fault?
