National History Day culminates in a national contest each June after a series of competitions held first at the school, regional, and then state levels. Each region and state sets its own registration and competition deadlines each year. Most students start research by late October or early November. Projects planning to enter the contest must be finished in time for the district contests (usually in February or March). The state contest (usually held in April-May), and the national contest (held at the beginning of June at the University of Maryland). Because papers are due several weeks before each contest, students writing papers and websites should plan ahead carefully.
