CourseMaster (CM) is a Computer Based Assessment (CBA) system. This paper describes the motivation and aims for developing CM's Marking System. It also explains the architectural forces and design decisions that have been established in order to engineer the Marking System. The Marking System adheres to the rigid specifications of the initial CM's design, which are: reliability, coherency, security, feedbackrichness, extensibility and customisability. The above notions and the features that CM's Marking System provides are examined in detail. Concrete implementation issues are also discussed with conclusions on usability and extensibility observations.
