## About this program

Oklahoma National History Day (OkNHD) is the Oklahoma Historical Society's state affiliate of National History Day, an academic program for students in grades 6-12. Students choose a historical topic tied to the annual theme, conduct primary and secondary research through libraries, archives, museums and historic sites, and present their conclusions as papers, exhibits, performances, websites or documentaries. Projects are judged in the spring at regional, state and national contests by professional historians and educators.

Oklahoma students in grades 6-12. The 2027 state contest is held in person at the Oklahoma History Center in Oklahoma City on May 5-6, 2027, with the Junior Division on Wednesday and the Senior Division on Thursday. State registration is due April 15 and costs $15 per student, with a $25 late fee; every member of a group project registers separately.
