I’ll answer this question briefly and just note one  larger question.

The short answer is yes.

  1.  I think every law school offers a course on being a trial lawyer.
  2. In  addition, law school students have an opportunity to participate in mock trial competitions.  These are organized events in which law school students can compete against each other and against other schools in a simulated trial.
  3. Finally, many law schools offer programs in which students can, under the guidance of an lawyer, help clients with legal issues.  These programs can include trial-related work.

A larger question is whether these and other programs actually help prepare students to work in the real world.   Many law school students graduate from law school without knowing much about how to practice law.  This, combined with a weak job market, puts new law school graduates at a disadvantage.
