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

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

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

Assessors should ensure that candidates can:

troubleshoot testing equipment and testing issues related to production processes to identify causes of problems and recommend corrective action

identify causes of faulty or substandard performance

propose adjustments/ rectifications/ modifications

test results of adjustments/rectifications/modifications

locate, interpret and apply relevant information

maintain relevant workplace records

identify and safely handle products and materials

apply safety precautions appropriate to the task.

Context of and specific resources for assessment

This unit of competency is to be assessed in the workplace or simulated workplace environment.

This unit of competency may be assessed with:

MSL977001A Contribute to development of products and applications

MSL977003A Contribute to validation of test methods.

MSL977004A Develop or adapt analyses and procedures.

Resources may include:

standard laboratory equipped with appropriate equipment, samples, reagents and test methods

laboratory procedures and SOPs.

Method of assessment

The following assessment methods are suggested:

completion of a troubleshooting brief or a troubleshooting proficiency test

review of workplace troubleshooting briefs completed by the candidate

feedback from supervisors and/or clients

oral or written questioning to assess underpinning knowledge of equipment operation, troubleshooting procedures and problem solving techniques

simulated equipment failure scenarios.

In all cases, practical assessment should be supported by questions to assess underpinning knowledge and those aspects of competency which are difficult to assess directly.

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 and/or assessment support when required.

The language, literacy and numeracy demands of assessment should not be greater than those required to undertake the unit of competency in a work like environment.

This competency in practice

Industry representatives have provided the case studies below to illustrate the practical application of this unit of competency and to show its relevance in a workplace setting.

Manufacturing

Emission spectroscopy is a technique often used by technicians to troubleshoot problems resulting from contamination. For example, a sample of stainless steel that showed signs of corrosion was submitted to a chemical technician for analysis. The technician subjected the sample to a spark and compared the spectra of the composite steel to spectra of a control sample of stainless steel. The technician concluded that the vanadium concentration in the sample was higher than that of the control sample. After doublechecking the work, the technician passed the results back to the engineering staff who were able to find the source of error and correct the manufacturing problem.

Biomedical

The immuno-analyser has become non-functional. The senior technical officer notifies the laboratory manager and then checks out the instruction sequence for that assay, checks the diagnostics for the detection unit, and reagent and sample lines, and then runs the diagnostic check program provided by the company. The officer concludes that the fault is due to instrument failure.

Food processing

A food company received a large number of customer complaints regarding the taste of its flavoured yoghurt product. The technician asked their sales representative to collect samples of the product from sales outlets while she/he collected retained reference samples with the same batch number/expiry date for examination. The technician developed a strategy for troubleshooting the production process and followed the following steps:

analysis of the returned product and reference samples indicated that the sugar concentration was above specification in both, suggesting that an error occurred during manufacturing or packaging

examination of batching sheets with the appropriate product code indicated that the correct formula and quantities of raw materials were used

retention samples were re-analysed and indicated that all were within specification

discussions with operators did not uncover any cause for the defect

observation of the process indicated that a non-standard batching drum was being used

discussions with the operator revealed that the tared standard drum used for weighing raw materials had been damaged and a lighter non-standard drum was being used with the original tare weight.

Analysis of the sugar content in the yoghurt indicated that the increased sugar content was due to the incorrect tare weight.

Required Skills and Knowledge

Required skills include:

troubleshooting testing equipment and testing issues related to production processes

identifying causes of faulty or substandard performance

proposing adjustments/rectifications/modifications

testing results of adjustments/rectifications/modifications

locating, interpreting and applying relevant information

maintaining relevant workplace records

identifying and safely handling products and materials

applying safety precautions appropriate to the task

Required knowledge

Required knowledge includes:

theoretical and practical aspects of laboratory equipment and processes

principles and procedures of testing equipment operation

characteristics, capabilities and limitations of testing equipment and its components

troubleshooting procedures for testing equipment

possible effects of matrix and impurities on analytical method

troubleshooting procedures for production processes

regulatory and licensing/testing requirements
