the potential implications of the variety of adjustments that could be made in response to test results

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

This competency requires evidence of competency in the selection of appropriate test methods from a prescribed range of tests for various scenarios and the interpretation of test results against predetermined specifications and standards The scenarios materials and test results should be relevant to the foundry industry and may be drawn directly from the workplace or may be simulated case studies

Tests may be conducted in either a workplace or suitable laboratory facility

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

Assessors should ensure that candidates can competently and consistently

select appropriate test methods

obtain repeatable results

interpret test results for a foundry

successfully complete several scenarios requiring the selection of different tests

obtain reproducible test results from testing across different samples requiring different sample preparationtest conditions

Context of and specific resources for assessment

Assessment may occur on the job or in an appropriately simulated environment Access is required to real or appropriately simulated situations including work areas materials and equipment and to information on workplace practices and OHS practices

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 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

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

Standards and industry codes of practice

Prescribed range of tests
