Forum Theatre – when it should be used?

We are at the end of a project that aims to map and combat early school leaving. We were working together with a school where the students are solely socially disadvantaged kids, a lot of them already left the school, but has now a second chance.
At the first phase of the process we tried to discover the reasons why one leaves the school, asking parents, children and teachers. Based on the results the rehearsals started. At the short video you can see this process. What do you think about the results? Is the target group and the method a good match? Do you have any similar experience?
