Pose after pose, it's hard for some Knox County students not to smile during a photo shoot.
"I love to sing and to show off my voice," says contestant Doretha Benn.
"It's my senior year and I thought I would take a chance, " says fellow contestant Sierra Trott.
The first-ever "CTE Goes Idol" features 13 contestants representing every high school in Knox County. They include Aryssa Puckett of Central, Beth Ann Stripling of Bearden, Brianna Hodge of Karns, Cameron Rogers of Powell, Doretha Benn of Carter, Janna Renee Crisp of Fulton, John Young of South Doyle, Josh Cottrell of Halls, Kevyn Meheula of West, Leah Bunch of Gibbs, Rachel MacLean of Farragut, Sierra Trott of Hardin Valley, and Xzavian Wrushen of Austin East.
"I think it's a really great opportunity for all the local people here," said Leah Bunch.
The idea found its voice just months ago.
"The next thing I know the whole thing just blew out of proportion," says Rick Brise with Knox County Career and Technical Educational Foundation. "It exploded."
Now, time is ticking. The singing showdown is set for April 8 at Market Square.
The concert will be free. In addition to recording a song, the single will be played on WIVK. Plus, the winning student will perform at the Tennessee Valley Fair.
