In 1996, Capitol Records was preparing a contract for Underwood but canceled it when company management changed. Underwood said of the event, "I honestly think it's a lot better that nothing came out of it now, because I wouldn't have been ready then. Everything has a way of working out." While at Checotah High School, she was an Honor Society member, a cheerleader, and played basketball and softball. Underwood graduated from Checotah High School in 2001 as salutatorian.
