Proposed Unit 3 assessment

The nature of assessment tasks in the current and proposed study designs are similar although only two Outcomes exist currently for Unit 3 and three Outcomes are included in the proposed study design. Some assessment tasks have been updated to reflect current assessment practice and the nature of the discipline. An indication of time for the task is intended to provide greater comparability in the scope of the tasks across classes and schools, and to reduce School-assessed Coursework load for teachers and students.
