Overview of Assessment

This unit is to be assessed in a simulated workplace and under the normal range of work conditions.
Practical exercises, presentation of competency assessment exercises & written tests are used.

Assessment Tasks

Practical exercises:

  1. Hawley/ Expansion Retainer & Soldering Orthodontic Appliance\
  2. Cast Partial Co/Cr Addition, Laser Weld & Self Cure

Assessment guidelines for the practical exercises, as outlined in the practical exercise book.

Theoretical examination

Join Alloy Structures

One element of the 3 hour exam (divided into competencies) PASS MARK 60%, If ’NYC’ (Not Yet Competent) result is achieved the student will be provided with detailed feedback of the shortcomings and given a further opportunity to sit a secondary exam.

If a grade of 40% or less is achieved the student will NOT be granted an opportunity to sit a secondary exam and the student will be required to re-enroll in the unit which will be incurr fees.

Please note: A subsequent NYC result for any of above mentioned assessments may require the student to attend further class work within their enrolment period or may result in the student re-enrolling in the unit which will be incurring fees.

Assessment Matrix

Other Information
