DC History Center is the official NHD affiliate for Washington, DC

National History Day in DC

National History Day is an annual project-based contest for students in grades 6-12. Each year, over 2,000 DC students do in-depth research to create original documentaries, exhibits, performances, research papers, or websites exploring a breadth of historical topics within an annual theme.

Like a science fair, but for history
The Basics

National History Day (NHD) is an annual project-based competition for students in grades 6-12. Students select a topic of interest related to the year’s theme, and produce a paper, exhibit, performance, documentary, or website presenting the conclusions and evidence from their research and analysis.

As the DC affiliate, the DC History Center runs a city-wide effort to provide access to relevant resources and content experts for students as they research, revise their work, and connect it to the year’s theme.

School-wide contests are managed by individual teachers and schools and are held in January and February. Students advance from the school, club, or homeschool level to the NHD in DC contest in March. NHD in DC winners advance to the national competition in College Park, MD in June.
