Oklahoma National History Day (OkNHD)

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.

Projects are judged in the spring at regional, state and national contests by professional historians and educators. The 2027 state contest is held in person at the Oklahoma History Center in Oklahoma City on May 5-6, 2027, with registration due April 15 and a $15 per student cost (with a $25 late fee).

Cost is $15 per student for registration, with a $25 late fee; every member of a group project registers separately.

Open to students in grades 6–12.
