Each year the History Day program has a theme by which students are required to implicate into their projects. The themes are chosen by the National office. Each theme is broad so that any teacher can incorporate into their curriculum in order to meet the required education standards for their grade level.
Here are the themes for the next few years:
2009: The Individual in History: Actions and Legacies (PDF)
