A Mock Trial is an act or imitation trial. Mock trials simulate
lower-court trials. Attorneys preparing for a real trial might use a
mock trial consisting of volunteers as role players to test theories or experiment with each other. In a mock trial normal rules of court are often abbreviated in order to focus on particular parts of the trial. Mock Trial is also the name of an extracurricular program in which students participate in rehearsed trials to learn new skills and compete with each other. At some law schools, the term trial advocacy is used for the program. Various organizations, such as state bar associations, sponsor Mock Trial/trial advocacy competitions for middle school students, high school students, college students, and law students.

Interscholastic mock trials take place on three levels. High-school
competitive mock trial has an annual national competition governed by National Mock Trial Championship, and the Constitutional Rights Foundation. The competition on the college circuit is governed by the American Mock Trial Association. The college circuit also has an online forum at Perjuries Mock Trial AMTA Forum. Finally, there is mock trial/trial advocacy at the Law School level such as the National Trial Competition hosted by the Texas Young Lawyers Association and the American College of Trial Lawyers.
