Before constructing your entry, carefully read the National History Day contest rule book. Review the competition's overview of all contest category rules, individual category rules, and how entries are judged. During each level of the competition, entries will be partially evaluated on rules compliance, and judges will determine if a project respects the word limit, includes required elements such as the annotated bibliography and process paper, and meets any length, time, or size requirements. Check out the contest FAQs, as well.
