For the first time since 1970, fifteen semi-finalists competed in the final competition, although not all the semi-finalists competed in both the swimsuit and evening gown. Following the new format established at Miss Universe 2003 and Miss Teen USA 2003, the top fifteen semi-finalists were reduced to ten after the evening gown competition, and then to the final five after swimsuits. This was the first time that contestants did not have the opportunity to compete in both competitions. This was also for the first time since 1979 that the pageant took place in the month of April.
For the second year, there was a Miss USA Fear Factor special, in which Tara Darby of Alabama won the $50,000 prize (half of which to be donated to the charity of her choice).
