Nickname given the driver talent search used by Roush Racing for its NASCAR Craftsman Truck Series teams. Young, aspiring NASCAR drivers are selected by Roush Racing personnel to audition in front of a panel consisting of Roush Racing NCTS experts. Elements of the audition process include a practice session where the driver assesses the chassis and makes requests to ultimately achieve the quickest and most consistent lap times. After the practice session, a 20-lap hot session takes place and the driver that shows the most improvement and knowledge not only behind the wheel, but also with adjusting setups, will be considered for the next open seat within the program.

Past winners include Kurt Busch and Greg Biffle.
