Assessment Conditions

This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is, the candidate is not in productive work, then a simulated working environment must be used that reflects realistic workplace situations and conditions.

The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team.

Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.

Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure its correct interpretation and application.

Assessment may be applied under project related conditions (real or simulated) and require evidence of process.

Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.

Assessors must be satisfied that the candidate can competently and consistently:

identify and explain the application of basic scientific principles and engineering techniques to avionic engineering situations

for given avionic engineering situations, identify and apply the relevant basic scientific principles and techniques

perform necessary calculations using appropriate applications and evaluate solutions

document appropriately the outcome of application of basic scientific principles and techniques to given avionic engineering situations.

Assessment may be in conjunction with assessment of other units of competency where required.

Assessors must satisfy the requirements of the National Vocational Education and Training Regulator (Australian Skills Quality Authority, or its successors).
