2017 National Contest
June 11 - June 15
Each year nearly 3,000 students with their families and teachers gather at the University of Maryland, College Park for the week-long event. These enthusiastic groups come from all over the United States, Guam, American Samoa, and international schools in China, Korea, South Asia, and Central America. The NHD excitement can be felt across the campus. After spending months on project research and preparation, and competing at local and affiliate contests, these students are eager to show their hard work at the national level.
