National History Day: Complete Student and Teacher Guide
Published · Subject: History & Humanities · Grades: 6–12
National History Day (NHD) is among the most underrated academic competitions in the United States. It attracts roughly half a million student entries per year from grades 6–12 and culminates at a national contest held in June at the University of Maryland. Unlike most competitions on this site, NHD does not test a fixed body of knowledge — it rewards original historical argument, primary source research, and the ability to place a topic in its historical context. The students who reach nationals have done genuine historiographical work.
The annual theme
NHD operates around an annual theme that changes each year. The theme is announced in the late summer for the upcoming academic year and is broad enough to accommodate projects in any period of history, any geography, and any discipline. Past themes have included “Frontiers in History,” “Communication in History,” and “Breaking Barriers in History.”
Students must connect their project to the theme in a substantive way — not superficially (any event can be superficially connected to any theme) but analytically. How did this event, person, or development engage with the theme’s central tension? The argument connecting the topic to the theme is part of what judges evaluate.
Entry categories
Students may compete in five categories, individually or as part of a group (group entries are limited to 2–5 students):
- Historical Paper: Individual only. A research paper of 2,500–10,000 words (including footnotes, excluding bibliography). The only category that requires written prose as the primary output.
- Exhibit: A physical display up to 40 inches wide, 30 inches deep, and 6 feet tall. Individual or group. Combines visual display with written components; three-dimensional media allowed.
- Documentary: An original documentary film, 10 minutes maximum. Individual or group. Credits and title cards do not count toward the time limit.
- Performance: A dramatic presentation of the student’s historical argument, 10 minutes maximum with 5 minutes for questions. Individual or group. Does not need to be dramatic in the theatrical sense — it can be a lecture-style presentation with visual aids.
- Website: A student-built website with 1,200–1,500 words of student-composed text (excluding primary source excerpts), 20-minute maximum visit time. Individual or group.
How the competition is structured
NHD runs through a four-tier structure:
- Classroom/school contest: Many schools run internal contests to select representatives to the next level; this is not universal.
- Regional or district contest: Varies by state; some states run regional contests, some go directly to state.
- State contest: Run by the state NHD affiliate (most states have one; check the NHD website for your state). Typically held in spring. Top finishers in each category advance to nationals.
- National Contest: Held in June at the University of Maryland, College Park. Students present to panels of professional historians and educators.
What judges are looking for
NHD judges are historians, educators, and museum professionals. They evaluate three things:
- Historical quality: Is the historical argument accurate? Is it based on primary sources? Is the student placing the topic in its broader historical context? Does the student understand the historiography (how historians have interpreted this topic)?
- Relation to theme: Is the connection to the annual theme substantive and analytical, or superficial?
- Clarity of presentation: Is the argument clearly communicated in the chosen format? Does the presentation support the argument?
Projects that rely exclusively on secondary sources (encyclopedias, general histories, Wikipedia) score significantly lower than projects that incorporate primary sources — original documents, photographs, newspaper accounts, oral histories. Identifying and using primary sources relevant to your topic is the single most important factor in advancing past the state level.
Finding primary sources
For US history topics: the Library of Congress (loc.gov) offers millions of digitized primary source documents, photographs, and newspapers. The National Archives also has digitized collections. State archives, local historical societies, and university special collections often have unique primary sources not available elsewhere. For topics involving living people, original interviews are considered primary sources.
For international history topics: the topic will typically determine the relevant archives. European national archives, international organization records, and diplomatic history document collections are increasingly digitized.
When to start
The NHD theme is announced in August or September for the upcoming academic year. Students who reach state or national competitions have typically begun research in September or October and conducted their primary source research before December. Rushing research into January and February produces lower-quality projects.
Teacher tip: the most effective NHD projects often emerge from a student’s genuine curiosity about a specific person, event, or question — not from a search for a topic that fits the theme. Help students find the topic they actually want to know about, then build the thematic argument around genuine interest.
