Overview of Assessment

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.

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 Task 1

(Available: Day 1)

 

Knowledge Assessment

 

This knowledge submission is to be completed outside of class hours.

 

Assessment must be researched, completed and submitted by the due date issued by assessor.  The due date will be published on CANVAS.

 

Students will be required to log into CANVAS to submit their assessment paper prior to the due date.

 

Feedback will be provided via CANVAS and students will have the opportunity to resubmit any completed assessment that is deemed unsatisfactory (one re-submission is allowed per assessment task). 

 

In order to achieve a Satisfactory result, students must complete ALL questions successfully on their re-submission.

 

More details and assessment requirements will be provided on CANVAS.

 

 

Assessment Task 2

(Days 5, 8 & 9)

 

Practical Assessment

 

This assessment is conducted at RMIT Dental Technology Simulated Laboratory rooms and student's knowledge and skills will be observed.

 

Detailed information will be provided to students via Canvas and during their class attendance.

 

In order to proceed with this assessment task, student must wear appropriate laboratory PPE and attire.

 

Students will attempt this assessment under supervision of the assessor and they will be marked with either “S” (Satisfactory) or “NYS“ (Not Yet Satisfactory) according to the assessment guidelines and criteria outlined in the HLTDET007 Assessment document.

 

All assessment criteria must be successfully completed in order to achieve a satisfactory result and students will receive verbal and written feedback.
