Overview of Assessment

You must show evidence of the ability to complete tasks outlined in elements and performance criteria of this unit, manage tasks and manage contingencies in the context of the job role. There must be evidence that you have:

• used standard precautions and safe work practices to prepare models, using a range of materials specifically prepared against written instructions and manufacturers’ instructions, for at least 4 different types of impressions (must be a combination of maxillary and mandibular arches):

   - dentate

   - partially dentate

   - edentulous

• critically evaluated the 4 different types of models produced to meet technical laboratory and clinician requirements.

To be deemed competent you must demonstrate an understanding of all aspects required of the competency.   

Regular attendance is necessary. 

Assessment methods have been designed to measure your achievement of each competency in a flexible manner over multiple tasks and consist of theory and practical based tasks.

Assessment Tasks

Students enrolled in Vocational Education and Training qualifications are assessed for Competency. To be assessed as Competent means you have consistently demonstrated the required knowledge and skills at a standard expected in the workplace.  

To be assessed as Competent in this course, you will need to complete each assessment task to a satisfactory standard. You will receive feedback from the teacher at the conclusion of each assessment task. 
You should refer to the assessment brief which is available through Canvas for full assessment criteria 

Assessment Task 1: Construct models knowledge assessment due  26/04/21 

Assessment Task 2:Construct models practical assessment due Block 1 - Week 2 (26/3/21)


Results that apply to courses that are delivered and assessed in accordance with competency-based assessment are: 

CA: Competency Achieved 
NYC: Not Yet Competent 
DNS: Did not Submit for Assessment 


Assessment Matrix

The assessment tasks listed in this course guide address all the elements and criteria of the requirements of this course.
