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, theoretical 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 60%) 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:

• Assessment should replicate workplace conditions as far as possible
• Consistent compliance with current infection control guidelines, Australian Standards and legislative requirements
• 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:
- consistent transfer of all records
- consistent mounting of models with attached registrations rims in accordance with requirements.

Context of and specific resources for assessment:

• 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
