Overview of Assessment

The assessment is conducted in both the theoretical and practical aspects of the course, following the performance criteria set in the National Training Package. 
Assessment methods may encompass a variety of approaches, including written and oral activities, as well as the demonstration of practical skills aligned with 
relevant industry standards. Participants should be aware that they may be asked to personally demonstrate their assessment activities to their teacher or assessor. 
Feedback will be consistently provided throughout the course.To successfully complete this course, you will be required to demonstrate competency in each assessment 
task within this unit. Full assessment details will be provided and can be found on CANVAS.
