North Carolina students competed in the 2013 National History Day event. National History Day (NHD) is a highly regarded academic program for elementary and secondary school students. Each year, more than half a million students, encouraged by thousands of teachers nationwide participate in the NHD contest. Students choose historical topics related to a theme and conduct extensive primary and secondary research through libraries, archives, museums, oral history interviews and historic sites. After analyzing and interpreting their sources and drawing conclusions about their topics' significance in history, students present their work in original papers, websites, exhibits, performances and documentaries. These products are entered into competitions in the spring at local, state and national levels where they are evaluated by professional historians and educators. The program culminates in the Kenneth E. Behring National Contest each June held at the University of Maryland at College Park.
