West Point is the four-year military school in New York State that educates future Army officers. The students are called cadets. They do not have to pay for their education. All student costs are paid by the United States Army. But the students do have to agree to serve on active duty in the Army for at least five years after they graduate. It is difficult to become a student at West Point. Only about 15 percent of students who apply are accepted. They must be nominated to the academy, usually by a federal or state lawmaker. Nominees also must satisfy the entrance requirements. These include excellent physical condition and high marks in school. West Point also accepts a limited number of international students nominated by their home government. They also must satisfy the physical and educational requirements. After graduation they return to their home countries to serve in their country's army.
