From the James Madison Memorial Fellowship Foundation website:

Through a national competition, the Foundation offers James Madison Fellowships to a select group of individuals desiring to become outstanding teachers of the American Constitution. The Madison Foundation is committed to providing graduate training in American history, American government, and social studies education that will help our nation's teachers improve and perfect their professional skills by gaining content knowledge of the Constitution.

The Foundation offers two types of fellowships. Junior Fellowships are awarded to students who are about to complete, or have completed, their undergraduate course of study and plan to begin graduate work on a full-time basis. Junior Fellows have two years to complete their degree. Senior Fellowships are awarded to teachers who wish to undertake work for a graduate degree on a part-time basis through summer and evening classes. Senior Fellows have up to five years to complete their degree. The fellowships are intended exclusively for graduate study leading to a master's degree.

James Madison Fellows may attend any accredited institution of higher education in the United States. Each individual entering the James Madison Fellowship Program will be expected to pursue and complete a master's degree in one of the following (listed in order of the Foundation's preference): Master of Arts (MA) in American history or in political science (also referred to as "government and politics" or as "government"); Master of Arts in Teaching (MAT) concentrating on either American Constitutional history (in a history department) or American government, political institutions, and political theory (in a political science department); or Master of Education (MEd) or the Master of Arts or Master of Science in Education with a concentration in American history or American government, political institutions, and political theory.
