In this paper we report ongoing work in the development of diagram interpretation and assessment applied to entity-relationship diagrams (ERDs). We report on our development of an automated marking tool and the results of two largescale experiments with this tool. We give an overview and the results of some initial, informal, evaluation of a student revision tool that we developed as a result of our experiences working on the automated marking system.
