Admission to the bar in the United States is the granting of permission by a particular court system to a lawyer to practice law in the jurisdiction. Each U.S. state and jurisdiction (e.g. territories under federal control) has its own court system and sets its own rules and standards for bar admission. In most cases, a person is admitted or called to the bar of the highest court in the jurisdiction and is thereby authorized to practice law in the jurisdiction. Federal courts, although often overlapping in admission standards with states, set their own requirements. Typically, lawyers seeking admission to the bar of one of the U.S. states must earn a Juris Doctor degree from a law school approved by the jurisdiction, pass a bar exam and professional responsibility examination, and undergo a character and fitness evaluation, with some exceptions to each requirement. A lawyer admitted in one state is not automatically allowed to practice in any other. Some states have reciprocal agreements that allow attorneys from other states to practice without sitting for another's bar exam. The use of the term bar comes from English custom. In the early 16th century, a railing divided the hall in the Inns of Court, with students occupying the body of the hall and readers or benchers on the other side. Students who officially became lawyers were "called to the bar", crossing the symbolic physical barrier and thus "admitted to the bar". In modern courtrooms, a railing may still be in place to enclose the space which is occupied by legal counsel as well as the criminal defendants and civil litigants who are before the court. The first bar exam in what is now the United States was instituted by Delaware Colony in 1763, as an oral examination before a judge. Many other American colonies soon followed suit. In the early United States, most states' requirements for bar admission included a period of study under a lawyer or judge (a practice called "reading the law") and a brief examination.
