"What Is History Day in Connecticut?
"History Day in Connecticut is a year-long academic program for middle and high school students in which participants choose a historical topic to research using primary and secondary sources. Working individually or in groups, students create a project of their own choice: a paper, exhibit, documentary, website, or performance. The projects are evaluated by teams of volunteer judges at District Contests in the spring. Students who place third or higher advance to the State Contest who place in the top two there advance to the National Contest held each June at the University of Maryland. Students not only learn history, they actually do history. Last year, over two thousand Connecticut students participated at the school, District, State and National levels."
