Maple TA is a system for creating and delivering online tests. It has much more sophis- ticated abilities for the random generation and grading of questions than other available online systems such as Blackboards built in assessment tools. It has been used for large classes in the School of Maths and Stats for several years and is currently in the process of being more closely integrated with the Universitys central systems and is a part of UNSWs TELT (Technology Enabled Learning and Teaching) platform. I will give an overview how it has been used in some of the Schools large first and second year courses and report on our experiences.
