Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Prepare to take the photograph

  1. Compose the image so that the most important aspects are in the centre of the photograph
  2. Orientate the image so that subsequent photos are reproducible
  3. Ensure there is no calculus or plaque deposits on the teeth before the image is taken
  4. Locate the image source to be photographed appropriately in the depth of field so that the photograph is in complete focus
  5. Check the viewfinder to ensure there are no obstructions to the image

Instructions to Assessors

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

Observation of workplace performance is desirable for assessment of this unit

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

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

Method of assessment

Evidence of essential knowledge and understanding may be provided by:

traditional or online (computer-based) assessment

questions during workplace assessment

written assignments/projects

Case study and scenario as a basis for discussion of issues and strategies to contribute to best practice

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
