Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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

Observation of workplace performance is essential for assessment of this unit

Consistent compliance with infection control guidelines, Australian and New Zealand Standards and legislative requirements as they relate to the dental assistant's specific job role

Consistency of performance should be demonstrated over the required range of workplace situations

Completion of a logbook, which registers all radiographs taken, in accordance with the licensing requirements of Radiation Health

Context of and specific resources for assessment:

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

Resources essential for assessment include:

access to dental radiographic imaging units and resources normally used in the workplace

radiographic viewing equipment

Competency in this unit should be assessed using all the relevant resources commonly provided in dental practice. Specific resources may include:

relevant dental practice/organisation policy and procedures manuals such as:

incident reporting procedures

infection control guidelines and relevant Australian and New Zealand Standards

WHS policy and procedures

relevant state and territory legislation

manufacturer specifications for dental radiographic units

Method of assessment

Observation in the work place is essential. Assessment in the workplace must be flexible to allow for client confidentiality and organisation policies

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

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

Related units:

This unit should be assessed in conjunction with the following related competency units:

HLTDA410D Apply the principles of radiation biology and protection in dental practice

HLTDA411D Prepare to expose a prescribed dental radiographic image
