History Day
History Day is a year-long academic program for students in grades 4–12 that encourages research, critical thinking, and creative presentation. Students explore historical topics connected to an annual theme and present their work through exhibits, documentaries, performances, papers, or website
Top projects advance through school, district, and county competitions, with qualifying students moving on to the California State Finals and the National History Day Contest.
