A Mock trial is an act or imitation trial. It is similar to a moot court, but mock trials simulate lower-court trials, while moot court simulates appellate court hearings. Attorneys preparing for a real trial might use a mock trial consisting of volunteers to test theories or experiment with each other. In a mock trial the rules 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 contrived or fake 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 High School Mock Trial Championship, Inc.. The competition on the college circuit is governed by the American Mock Trial Association. The college circuit also has an unofficial online forum at Perjuries Mock Trial. 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.
