He and nine other finalists from grades 4, 5 and 6 competed in the first elimination round.
After many rounds and many ties, Kiernan became the school champion by correctly answering the question "The Taklimakan Desert, home to the Uyghur people, is located north of the Kunlun Mountains in which Asian country?" Kiernan knew it was China.
As winner, he will take a written test to see if he is among the hundred students who move on to the state competition.
The state winner is provided an all-expenses paid trip by the National Geographic Society to the national championship in Washington in May.
