The disk takes about an hour to complete, depending on the detours you take to Law students or staff, even experienced staff, could benefit from the disk. The fact pattern is far from the issues we deal with, but the basic evidentiary issues are similar to those which arise in our trials. It's hard to compare these CDs to live training. I think there is a place for both, and neither duplicates the other. For new staff with performance anxiety, there is probably some benefit from tools which can be used alone.
CDs also allow the student to leave the exercise to do reading on screen.
This one also has some options for video commentary by a trial lawyer on trial tactics. Live training skills training may more realistically duplicate courtroom work, we rarely have NITA-type training available. I have also used the Harvard interactive CDs. Those look a little dated, but they work fairly well, and have the advantage of being based in a legal services eviction case. On the plus side, I thought that the PLI CDs provide more opportunity for learning about trial tactics, and more detours to more intensive written information on different evidentiary issues.
