Overview of Assessment

Practical exercises, presentation of competency assessment exercises & written tests are used

Assessment Tasks

The assessments in this unit are undertaken in a simulated workplace and under the normal range of work conditions in the form of practical exercises, a practical competency and a theoretical exam (PASS MARK 70%) all of which are to be
co-assessed with the following units;
HLTIN301A: Comply with Infection Control,
HLTOHS300A: Contribute to OHS Processes,
BSBCMN302A: Organise Personal Work Priorities,
BSBCMN305A: Organise Workplace Information
All forms of assessments and co-assessed units are to be passed to pass this unit.

Assessment Matrix

Critical aspects for assessment and evidence required to demonstrate this competency unit:
• Consistent compliance with current infection control guidelines, Australian Standards and legislative requirements as they relate to the dental technician’s specific job role
• Consistent compliance with occupational health and safety policies and procedures as they relate to the dental technician’s specific job role
• Consistency of performance should be demonstrated over the required range of workplace situations including:
- consistently design and manufacture oral splints using a range of materials, for a range of jaw relations and malocclusions
- consistently use a range of articulators
• consistently trim, polish, finish and evaluate oral splints for suitability for insertion in the mouth

Context of and specific resources for assessment:
• Assessment should replicate workplace conditions as far as possible
• Simulations may be used to represent workplace conditions as closely as possible
• Where, for reasons of safety, access to equipment and resources and space, assessment takes place away from the workplace, simulations should be used to represent workplace conditions as closely as possible

Method of assessment
• Evidence of essential knowledge and understanding may be provided by:
- traditional or online (computer-based)
assessment - written assignments/projects
• Case study and scenario as a basis for discussion of issues and strategies to contribute to best practice
• Questioning
• Staff and/or client feedback
• Supporting statement of supervisor
• Authenticated evidence of relevant work experience and/or formal/informal learning
• Role play simulation
