The Unified Modeling Language (UML) is probably the most widely known and used notation for objectoriented analysis and design. UML consists of various graphical notations, which capture the static system structures (class diagrams), system component behaviors (state transition diagrams) and system component interactions (collaboration and sequence diagrams). UML notations can be produced with the help of CASE (Computer-aided software engineering) tools such as Rational Rose. Basically, we proposed the development of an Assessment system for UML class diagram, the UML Class Diagram Assessor (UCDA). This tool will receive a students UML class diagram in the form of Rational Rose petal files. In this paper we present a design of UML Class Diagram Assessor (UCDA) that evaluates UML class diagrams automatically. UCDA evaluates the diagram based on three aspects: its structure; its correctness and language used. The output of UCDA is a list of comments on a diagram that is hoped to guide students in understanding on how to represent the system requirement in UML model correctly.
