Study Options

Option 1: Workplace Based

Our Trainer Assessor will conduct all teaching and assessment at your place of work, this is available to both Appreciates and Full Fee students. Please note: If your workplace doesn’t have the required scope of work for a particular unit of competency we can conduct the training and assessment at our campus.


 Option 2: Classroom Training

All your learning and assessment for each of the units is delivered in a classroom environment with other students (classroom training requires a minimum of 5 students).


Option 3: Recognition of Prior Learning (RPL)

If you’ve had lots of experience in this industry (or similar), you may be eligible for RPL.


Recognition of Prior Learning means that you don’t require the training but rather you need to be assessed on each unit. You will need to draw on all of your past experiences so that you can demonstrate that you have already acquired the knowledge and skills.
