Usually instructors develop a narrative for the actor who stays in character for the entire interaction with the students. Students take turns interacting with the character to rehearse their skills. After the simulation has ended actors usually engage with students to provide feedback about their experience in the simulation and how their character felt. In social work, simulations can include individuals coming to a social worker with a range of personal problems, but can also include groups or family counselling scenarios. In law school, actors often play specific roles of clients in a negotiation process.
