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:

plan, monitor and adjust work flow to manage competing client/production priorities

ensure that the robotic sample preparation system operates efficiently and safely to produce outputs that meet the enterprise/client quality requirements

promptly identify/rectify common system problems

work closely with operators to improve safety, efficiency and quality.

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:

MSL944001A Maintain laboratory/field workplace safety

MSL977002A Troubleshoot equipment and/or production processes.

Resources may include:

access to a robotic sample preparation system

a variety of mineral ore samples, sample preparation methods, equipment and reagents

safety equipment

relevant enterprise procedures.

Method of assessment

The following assessment methods are suggested:

review of production logs, quality control, performance and analytical results traceable to samples prepared on shifts supervised by the candidate

review of system records prepared by the candidate

feedback from operators, service/maintenance technicians, clients and laboratory/production managers

written/oral questioning about robotic sample preparation procedures, common problems and their specified corrective actions.

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 study below to illustrate the practical application of this unit of competency and show its relevance in a workplace setting.

Mineral processing

An operator observes that the robotic sample preparation system is displaying an 'incorrect weight' error code and informs the shift supervisor. The supervisor notes that although the input weight for the sample being processed was 800g, the indicated output weight is zero. He/she immediately suspects that the sample is stuck in the bowl. He/she switches off the mill and tags it out so that the operator can continue unloading the completed samples. The supervisor checks the mill for a faulty hose but they are all functioning correctly. He/she decides that the problem could be in the grinding vessel and tries to manually discharge the sample with a pendant without success. After opening up the grinding vessel, he/she finds that a 'plastic' sample is stuck in the bowl. He/she replaces the grinding vessel with a new one. As he/she extracts the sample from the bowl, he/she notices a very strong smell of diesel. He/shesubsequently finds that the client's other samples are also contaminated and removes them from the input magazine. He/she deletes the client's worksheets from the robot control program, checks and synchronises the system and then restarts the robot. He/she reports the problem to the laboratory manager and asks him/her to notify the client of the diesel contamination and the laboratory's inability to prepare their batch of samples.
