Martin's parents attended the ceremony and accepted the teenager’s degree in aeronautical science on his behalf.
Martin, who had dreamed of being a pilot, was killed five years ago in Sanford, Fla., after being shot by community watch member George Zimmerman.
Martin's parent said the posthumous degree is bittersweet.
"I think this just shows what this community, how they feel, how they believe in our family, believe in our foundation. This was a day that we planned for as parents, we just wish that we would have watched him walk across the stage," said Trayvon’s father Tracy Martin.
Martin's mother graduated from Florida Memorial University located in Miami Gardens, Fla.
