Fans can vote for a delegate to reach the semifinals (Top 16) July 15-August 9. The fan vote was won by Missouri Brenda Smith-Lezana.
A preliminary round was conducted on August 9, a day before the finals.
The Top 16 was announced during the Final Show and they competed in the Swimsuit and Evening Gown rounds. After the Evening Gown competition, the girls were interviewed backstage by Karl Schmid, sending the show to an intermission. The Top 5 were announced and asked questions about themselves. Then the judges asked questions prepared for them. Each finalist were allowed 30 seconds to answer the question. The judges took one last look at the Top 5 Finalists and Logan West takes her final walk as Miss Teen USA before crowning her successor, Cassidy Wolf.
