Virginia's Parker Hall was confined to a wheelchair three years ago following a devastating car accident.
He was told there was less than a 5 percent chance he'd ever walk again, according to Daily Mail.
But he pushed himself so hard in physical therapy, by last year, his family set a daunting objective for his graduation.
Parker's mother, Miriam, told FOX 5 DC she recalled saying,
Parker's physical therapist wheeled him up to the stage for C. D. Hylton High School's commencement ceremony on June 7.
The audience gave the 18-year-old a standing ovation as he stood up and, with the help of a cane, crossed the stage to receive his diploma.
