Elements and Performance Criteria

RANGE STATEMENT

The Range Statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts.


Preparation of the model may include:
Identification and blocking out of undercuts
Identification of tray periphery
Identification of areas that require relief
Identification of the final position of the occlusal rims


Base material may include:
Acrylic resin
Heat or vacuum formed thermoplastic
Shellac
Wax with a wire strengthener


Industry standard may include but is not limited to:
Adequate placement of strengtheners
Constructed of materials that are dimensionally stable at mouth temperature
Homogeneous application of wax free of voids
Rims that are neat and tidy with no wax on tissue fitting surface
Rims that are smooth and rounded
Rims that are stable on the model
Rims that are well adapted to the model


Construction to prescribed dimensions and appropriate landmarks may include:
Appropriate clearance of fraenal and muscle attachments
Appropriate height and width of occlusal rims
Peripheries filling the depth and width of the sulci

EVIDENCE GUIDE

The evidence guide provides advice on assessment and must be read in conjunction with the Performance Criteria, Required Skills and Knowledge, the Range Statement and the Assessment Guidelines for this Training Package.

Critical aspects for assessment and evidence required to demonstrate this competency unit:
The individual being assessed must provide evidence of specified essential knowledge as well as skills
Assessment should replicate workplace conditions as far as possible
Consistency of performance should be demonstrated over the required range of workplace situations


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


Access and equity considerations:
All workers in the health industry should be aware of access and equity issues in relation to their own area of work
All workers should develop their ability to work in a culturally diverse environment
In recognition of particular health issues facing Aboriginal and Torres Strait Islander communities, workers should be aware of cultural, historical and current issues impacting on health of Aboriginal and Torres Strait Islander people
Assessors and trainers must take into account relevant access and equity issues, in particular relating to factors impacting on health of Aboriginal and/or Torres Strait Islander clients and communities
