National Contest Judges’ Information

The 2023 National History Day Contest will be held June 11-15, 2023 at the University of Maryland, College Park. National History Day (NHD) is looking for historians, educators, and others to judge student projects. Judging dates will be June 12-13, 2023.

Students in 6th through 12th grades conduct extensive research on topics related to an annual theme and present their findings as historical papers, exhibits, documentaries, performances, and websites.

Registration for judges will open in the fall of 2022.

If you have any questions, please contact judges@nhd.org.

Judging Process
Judging Process

NHD relies on consensus judging. That means that instead of giving entries numeric scores, you will be ranking them. If you are confirmed as a judge, you will be assigned to a team of 3 judges, one of whom will be designated as the captain. It is important that everyone on your team agrees on the overall rankings of the entries you judge.
