We assume that they must experience and learn it. Law school moot courts are generally well funded and often give credit as well as status for doing well in their competition. The competition is run like a round robin in a tennis tournament. Everyone argues in the first round. Then those who score the highest in that round, compete against each other in the next round.
Schools often go on to regional competitions, and then national competitions.
We argue in rounds, as does the law school moot court. Everyone who wishes to compete to argue in the final exhibition rounds in our auditorium argues in the initial rounds. Eight students argue in the semi-finals, and four are chosen for the exhibition rounds. This pattern has presented us with a problem. After many years we reasoned out our choice.
