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!

Instructions to Assessors

Evidence Guide

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessment must confirm the ability to correctly fit oxygen masks to a minimum of three different people with no corrective action required by supervisor; to recognise a range of faults including incorrect manufacture; to correct a minimum of three unserviceable oxygen masks; and to work safely with oxygen.

Consistency in performance

Competency should be demonstrated over time with a range of fitments and maintenance to oxygen masks.

Context of and specific resources for assessment

Context of assessment

Competency should be assessed in the workplace or in a simulated workplace environment.

Specific resources for assessment

Access to oxygen masks, three live participants, stools and equipment for fitting and maintaining oxygen masks.
