The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package

Overview of assessment

A person who demonstrates competency in this unit must be able to analyse loads on a variety of frames and mechanisms to confirm performance and safety compliance

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

Assessors must be satisfied that the candidate can competently and consistently

identify and review features functions and performance requirement of frames beams and mechanisms

identify complex calculations requiring professional engineering assistance

establish dynamics design loads working stresses allowable deformations and factor of safety element arrangements for calculations to be done

evaluate assembly and fastening methods analysis techniques software and software validation techniques

analyse static and dynamic operating conditions and determine design or selection parameters

optimise frame beam and mechanism elements for strength deflection arrangement and fastening

communicate and negotiate with stakeholders professionals and technicians and make adjustments accordingly

evaluate frames beams and mechanisms for WHS and regulatory requirements and risk management compliance

report and document results

Context of and specific resources for assessment

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 then a simulated working environment must be used where the range of conditions reflects realistic workplace situations 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

Access must be provided to appropriate learning andor assessment support when required Where applicable physical resources should include equipment modified for people with disabilities

Method of assessment

Assessment must satisfy the endorsed Assessment Guidelines of the MEM Metal and Engineering Training Package

Assessment must satisfy the endorsed Assessment Guidelines of the MEM05 Metal and Engineering Training Package.

Assessment methods must confirm consistency and accuracy of performance over time and in a range of workplace relevant contexts together with application of underpinning knowledge

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

Assessment may be applied under projectrelated conditions real or simulated and require evidence of process

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

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

Guidance information for assessment

Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed

Structural support and machine elements

Machine mechanisms

Standards and codes

Load calculations to be done with, or obtained from, a professional engineer

Appropriate licensed technical and professional assistance
