Evaluating mediators is a complex process, but not an impossible one. While no single solution is likely to be found, a set of options is emerging. Any new refinement, admittedly, brings with it new difficulties, and the options laid out here are themselves complex to administer. An adroit program management may be able to put together relatively quickly a workable, efficient, and fair approach to evaluation that is tailored to its own circumstances. But most likely, the process of developing evaluation tools will require sustained effort, justified partly by recognition that only trial and error will eventually produce a result keyed to the program's, the parties', and the mediators' diverse needs.
