Overview of Assessment

You must demonstrate Performance and Knowledge Evidence of the unit in order to be deemed competent.
 Assessment methods have been designed to measure achievement of each competency in a flexible manner over a range of assessment tasks.
 You may be assessed by:
• Oral or written questioning
• Oral presentations
• Assignments and projects
• Direct observation of actual work practice
• Presentation of a portfolio of evidence which may comprise documents, and/or photographs and/or video and/or audio files
• Work-based activities
• Third-party feedback from a work supervisor/employer
 Primary assessment involves on-going practical and applied assessment in a clinical workplace or simulated environment such as a supervised student clinic or at a Work Integrated Learning (WIL) placement activity.

 Competency based training requires you to be in attendance in order for assessment to be undertaken.

 Feedback will be provided throughout the semester in class and/or online discussions, through individual and group feedback on practical exercises and by individual consultation.

 All Assessment tasks should be performed or submitted by their due dates.
 If due to illness or other unforeseen circumstance, you are unable to attend on the due date of an assessment (e.g. test, examination, oral, etc.) OR you do attend, but your performance has been affected, you may submit an APPLICATION FOR SPECIAL CONSIDERATION within 2 working days of the due date. If Special Consideration is granted, you will be given the opportunity to complete/repeat the assessment task at a later date. For advice on this application please visit www.rmit.edu.au/students/specialconsideration or speak to your Program Coordinator.
 If due to illness or other unforeseen circumstance, you are unable to submit by the due date (e.g. assignment, report, project etc.):
• you may submit an APPLICATION FOR EXTENSION OF TIME FOR SUBMISSION OF ASSESSABLE WORK for an extension of time of up to seven (7) calendar days or less. This must be lodged with the Program Coordinator 1 working day before the original due date. If granted, you will have the opportunity to submit up to 7 days later than the original due date. For advice on this application please visit www.rmit.edu.au/students/assessment/extension or speak to your Program Coordinator.
 Or:
• you may submit an APPLICATION FOR SPECIAL CONSIDERATION within 2 working days of the due date. If Special Consideration is granted, you will be given the opportunity to submit the assessment task more than 7 days after the original due date. For advice on this application please visit www.rmit.edu.au/students/specialconsideration or speak to your Program Coordinator.

 You are expected to prepare all assignments and other written work in a professional manner. More information on general academic study and writing skills can be found on the “Learning Lab” http://emedia.rmit.edu.au/learninglab/. All work submitted for assessment must be submitted electronically unless otherwise advised.

 Students must keep a copy of all submitted assessments including electronic copies.
 Harvard style is used for all referencing and for bibliography.

Credit transfer and RPL 
 Credit transfer is available to students who have already completed the same or similar courses. Recognition of prior learning is available to students who have relevant prior skills or experience. Please refer to http://www.rmit.edu.au/browse;ID=8u7jborsx9dy

 

 

 

 

 

 

 

 


Assessment Tasks

1. You will be required to complete a range of practical edging and fitting tasks, hand skills and repairs tasks and neutralisation tasks. These tasks are located in the Workplace Evidence Log.

2. Workplace Evidence log: a collection of evidence activities to prove competence, knowledge and skill in a variety of elements and performance criteria across a range of units.

3. Online quiz: this online assessment will prove competency in the essential knowledge required for this unit.

4. Case studies



Trainee groups Due Dates:

The Due Dates for assessments will vary for the individual Trainee groups. These dates will be posted in the "Assessment Dates" section of Blackboard.

 

Please note that you will need to demonstrate competency in all assessment tasks in order to achieve competency for this unit.
