Chenoweth graduated from OCU with a bachelor's degree in music in 1990 and a master's in opera performance in 1992, The Oklahoman reported.
She left the school determined to make a name for herself in the entertainment business, she said Saturday after receiving the award.
"Nothing was going to stop me," she said.
Since then, she has won a Tony Award for her performance in "You're A Good Man, Charlie Brown" and an Emmy Award for her work on the television drama "Pushing Daises."
Chenoweth said part of the credit for her success goes to OCU, as the university offered her the right combination of training and performance experience.
