OkNHD for Parents and Students

General Information

Students who participate in National History Day (NHD) develop and improve a number of skills including research, writing, presentation, and interviewing. Oklahoma NHD staff can assist students, parents, and teachers along the way and offer guidance when needed. There is an assortment of resources available from state NHD programs as well as the national NHD office to help make your student’s project a success.


Students who participate in NHD have several choices for presenting their research in creative form. Students can compete as individuals or in groups. In addition, students are divided into the junior division (grades 6–8) and senior division (grades 9–12) to help keep the contest competitive. They may enter one of nine categories:

  • Paper (individual only)
  • Individual Exhibit
  • Group Exhibit
  • Individual Performance
  • Group Performance
  • Individual Documentary
  • Group Documentary
  • Individual Website
  • Group Website

Each category in each division is judged separately. Group entries may include two to five students. Group participants do not have to be in the same grade to compete together, but they must be in the same division.

Read the Rules

Before your student begins working on an entry for the competition, you and your student should carefully read the National History Day Contest Rule Book. In order to ensure students across the country participate in a fair contest that judges students equally, National History Day sets the rules and guidelines for all participating entries. All judges are familiar with the rules.
