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.

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

Assessors should ensure that candidates can:

interpret test methods/procedures accurately

prepare and test samples in accordance with specified methods

ensure equipment/instrumentation is within calibration before use

safely operate test equipment/instruments to enterprise standards and/or manufacturer’s specifications

apply basic knowledge of physical properties of materials to interpret gross features of data and make relevant conclusions

identify atypical results, such as out of normal range or an artefact

trace and source obvious causes of an artefact

communicate problems to a supervisor or outside service technician

calculate, record and communicate results in accordance with enterprise procedures

maintain security, integrity and traceability of samples, sub-samples, test data/results and documentation.

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:

MSL924001A Process and interpret data.

Resources may include:

standard laboratory equipped with appropriate test equipment/instruments, standards and materials

enterprise procedures and standard methods.

Method of assessment

The following assessment methods are suggested:

review of test data/results obtained by the candidate over a period of time to check accuracy, consistency and timeliness of results

review of test records and workplace documentation completed by the candidate

observation of candidate conducting a range of physical tests and procedures and sample preparation

feedback from peers and supervisors

oral or written questioning of physical principles and concepts, test methods and enterprise procedures.

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

A technical assistant was measuring the specific density of a shipment of glycerol using a standard laboratory procedure. The result did not agree with the manufacturer’s certificate of analysis. The assistant notified the manufacturer who came to the plant and checked the delivered material. It had been raining while the glycerol was in transit and rain water had entered the drum, diluting the glycerol. The drum was returned to the manufacturer and a new drum was supplied to the manufacturing plant. The manufacturer investigated the seals on the glycerol drums and took action to ensure that new seals would protect the product in transit.

Food processing

A technician was testing the melt flow index of a new type of polymer that was to be used as a sealant for packages of freeze dried coffee. The technician measured the melt flow rate and found it was much too high. The technician then checked the melt flow equipment as per the manufacturer’s directions and found the machine was out of calibration. After recalibration using recommended standards, another sample was obtained and retested. This time, the polymer was within specification and was released for use in production.
