Should American high school students know at least as much about their country’s historic documents as immigrants seeking citizenship? Many states and schools are asking that question. People who want to become American citizens must know about the Declaration of Independence, the Constitution and the Federalist papers. These documents were written in the late 1700s by some of the founders of the country. But, some experts say American students generally know little about these founding documents. They say if students do not understand the documents, they cannot know how the American system of government operates. So, an increasing number of American schools are requiring students learn about these documents before they can graduate. Individual states are using different methods for teaching the subject.
