The 1,903-point career scorer transferred to Constitution from Academy of the New Church, in Bryn Athyn, last year.
Walker, who averaged 22 points and 7 assists, chose Central Florida over Tulsa and Seton Hall because of his relationship with assistant coach Tim Thomas, who recruited Walker for 21/2 years before the guard committed.
"It just felt like family to me," Walker said. "When I went on a visit, it felt very comfortable. I thought the coaches were being real honest with me. They laid everything out on the table."
Earlier in the school year, Walker held offers from other schools such as Temple and Pittsburgh, Constitution coach Rob Moore said. But as Walker waited to make his final decision, some schools filled their needs and moved on.
Walker considered enrolling at a prep school for a year. His decision took a long time, Moore said, in part because of sour experiences in high school. Before going to Constitution, Walker split his first two years between Roman Catholic and a private school in Florida.
"He didn't want to repeat the experiences from high school by going to the wrong college," Moore said. "He wanted to take his time, make sure he got it right."
Assuming he stays at UCF longer than his freshman season, Walker will get plenty of chances to play near Philadelphia. The Knights will join the Big East Conference beginning in the 2013 academic year.
