The class is scheduled for delivery to the APPRENTICE group in the Lecture theatre of Building 154 RMIT (within the Royal Dental Hospital Melbourne) Notification will be provided via student email if the date or location change.

Following the delivery of the theory class, practical exercises will be undertaken in the laboratory.

Class schedules are detailed in the timetables provided on Blackboard (subject to change at the discretion of RMIT, in this event notification will be provided to your student email);

  1. Practical classes will be delivered in the simulated environment at RMIT where the Teacher will provide demonstration and assistance as you construct the following appliances.
  • Mx Dual layer mouthguard
  • Mx and Md Bleaching trays


The TIER 2 exercises are made available if you complete all of the previous exercises and are seeking further practice prior to the assessments. The time guides for the TIER 2 exercises are reduced and require a ’self-managed approach’ to complete the exercise.

Overview of Assessment

You will be assessed in a simulated workplace and under the normal range of work conditions.

You will be assessed on both the essential knowledge and the demonstration of essential skills through;

  1. Completion of practical exercises - including detailed self-reflection or each exercise
  2. Practical exam
  3. Theory exam


Assessment Tasks

You will attempt the following practical exercise under supervision of the teacher and you will be graded with either a Px (Satisfactory) or NYC (Not Satisfactory) according to the assessment guidelines outlined in the practical exercise book; in accordance with the training package elements and essential skills.

  1. Mx Dual layer mouthguard
  2. Mx and Md Bleaching trays


The TIER 2 exercises are made available if you complete all of the previous exercises and are seeking further practice prior to the assessments. The time guides for the TIER 2 exercises are reduced and require a ’self-managed approach’ to complete the exercise. If you attempt the following practical exercises you will be graded with either a Px (Satisfactory) or NYC (Not Satisfactory) according to the assessment guidelines outlined in the practical exercise book; in accordance with the training package elements and essential skills.

  1. TIER 2 - Mx Dual layer mouthguard
  2. TIER 2 - Mx and Md Bleaching trays
     

Upon completion of an exercise and prior to submission for assessment, all exercises undertaken in the practical classes will require you to provide a detailed reflection of your own work focussing on areas of the appliance that were successful as well as areas that could be improved upon next time.

The practical exam will take place under supervision in the simulated working environment at RMIT. The exam will take place under exam conditions and you will be given details of the requirements and assessment guidelines in the practical book available in class and on BlackBoard.

PRAC EXAM - Mx Dual layer mouthguard

The theory exam will be conducted under supervision at RMIT under exam conditions.
