I doubt I know enough to ask good questions. The article has a very bare-bones reference to it, so here are some basic questions:

1. What is the high level objective?
2. Describe the training from the outside: when, where, who, how much?
3. Describe the training from the inside: what gets taught, what gets learned?
4. What role do you expect mentors to play?
5. How do you support the mentors in playing that role?
