National History Day (NHD) is a premier competition that engages more than half a million students nationally.  As part of NHD, Sacramento County History Day (SCHD) allows students to participate in authentic, challenging, project-based learning that lasts an entire school year.  Students select topics and research them as historians would – by using libraries, archives, museums and oral history interviews.  Their analysis and interpretations come together with the facts and evidence they've gathered to become their final projects.
