National History Day Arizona (NHDAZ) is a signature program of the Arizona Historical Society. Developed for middle and high school students, National History Day Arizona makes history come alive by engaging them in the discovery of the historical, cultural, scientific, and social experiences of the past. Through in-depth research, project-based learning, hands-on experiences, and presentations; Arizona students become better prepared to inform the present and shape the future. NHDAZ inspires teachers and students through challenging classroom activities, after school clubs, weekend workshops, and exciting competitions transforming history education and instruction.
