Welcome to National History Day California

What is National History Day?

National History Day – California (NHD – CA) is a year-long educational program, which encourages students to explore local, state, national, and world history. Orange County is proud to serve as the state affiliate and sponsor for NHD – CA. After selecting a historical topic that relates to an annual theme, students conduct extensive research by using libraries, archives, museums, and oral history interviews. They analyze and interpret their findings, draw conclusions about their topic’s significance in history, and create final projects that present their work. These projects can be entered into a series of competitions, from the local to the national level, where they are evaluated by professional historians and educators.
