Unrequested App Fee Waiver?

We got a “bill” showing a credit for the application fee as though it were waived; does anyone else know what this might mean? Thank you!

Follow-up - I just called the offices to see what’s what. The bursar’s office didn’t know, but the admissions office said that National Merit honors can lead to fee waivers (?) but I never heard of this before. Any other BTDTs?

Yes, there are some schools (UMD among them) that waive application fees for National Merit finalists (we were in that happy situation a couple of years ago :-).

The university waives the application fee for high school seniors who are National Merit, National Achievement or National Hispanic finalists or semifinalists.

I was expecting this for my daughter, as she is NMSF. I haven’t seen it yet. Maybe she received the email. I’ll check.
