This paper proposes an evaluation for modeling tool's adaptation by observing how well they can be used to customize graphical editors for a sample DSML proposed as a case study. It also discusses the current state of the art, and compares what was done in every tool that we have evaluated, according to relevant criteria. It was perceived; during our research that there is a clear need in term of criteria that supports evaluating Editor's customization quality. For this aim, we propose such criteria in this paper. We review tool's adaptation approaches, adaptation categories regarding different points of view and evaluate tools, with respect to their productivity and expressivity according to the proposed evaluation criteria.
