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, the Range Statement and the Assessment Guidelines for this Training Package.

Overview of assessment

A holistic approach should be taken to the assessment.

Assessors must be satisfied that the person can consistently perform the unit as a whole, as defined by the Elements, Performance Criteria and skills and knowledge.

Critical aspects

It is essential that competence is demonstrated in the knowledge and skills defined in this unit. These may include the ability to:

clarify the requirements of the modified compound

make an initial estimated formula and justify that initial formula

modify the formula based on test data and justify the modifications

make final adjustments for the scaled up formula to work successfully in the factory.

Consistent performance should be demonstrated through the evidence from several formula modifications requiring different types of changes.

Context of assessment

This unit may be best assessed either through a portfolio of compounds developed/ modified, or the use of projects to develop/modify a range of existing compounds.

Competence in this unit may be assessed:

on the plant

using questions to assess knowledge

in a laboratory/pilot plant

by using a suitable simulation and/or a range of case studies/scenarios

through a combination of these techniques.

Method of assessment

In all cases it is expected that practical assessment will be combined with targeted questioning to assess the underpinning knowledge and theoretical assessment will be combined with appropriate practical/simulation or similar assessment. Assessors need to be aware of any cultural issues that may affect responses to questions.

Assessment processes and techniques must be culturally appropriate and appropriate to the oracy, language and literacy capacity of the assessee and the work being performed.

Specific resources for assessment

This section should be read in conjunction with the Range Statement for this unit of competency. Resources required include suitable access to an operating plant or equipment that allows for appropriate and realistic simulation. A bank of case studies/scenarios and questions will also be required to the extent that they form part of the assessment method. Questioning may take place either in the workplace, or in an adjacent, quiet facility such as an office or lunchroom. No other special resources are required.

Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.

Required Skills and Knowledge

This describes the essential skills and knowledge and their level required for this unit.

Competence in this unit requires knowledge of:

the components of relevant compounds and their impact on compound properties

tests which might be used and the applicability of the different tests for different compound properties

mixing methods and the impacts of different mixing on compound properties

existing compounds and their properties

requirements for factory trialling and scaling up from laboratory/pilot scale

suppliers of materials

sources of information about materials.

Language, literacy and numeracy requirements

This unit requires the ability to read and interpret technical specifications and literature and to communicate with all relevant stakeholders.

Writing formulae/mixing instructions and similar documents.

Numeracy is required to interpret technical specifications and test results and to calculate quantities and proportions required for the formula, make adjustments and then to scale up to factory trials.

Range Statement

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts.

Where reference is made to industry codes of practice, and/or Australian/international standards, the latest version must be used.

Context

This competency applies to advanced operators who modify formulae for compounds used in the factory. They will typically be based in a laboratory or similar pilot/product/ material development area but will also have responsibility in the factory for monitoring new batches and ensuring that modified compounds are suitable when released for standard production.

A operator working at this level would typically be responsible to a more senior operator and would work closely with them on new compounds and major modifications of existing compounds.

The operator would not be expected to develop a new compound or make a major modification to an existing compound unless under the direction of a more senior operator.

Procedures

All operations are performed in accordance with procedures.

Procedures means all relevant workplace procedures, work instructions, temporary instructions and relevant industry and government codes and standards.

Health, Safety and Environment

All operations are subject to stringent health, safety and environment requirements, which may be imposed through State or federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between performance criteria and HSE requirements, the operator needs to ensure the HSE requirements take precedence.

Compound

Compound is used to mean any mixture of materials which is undertaken to a set formula and in specified proportions.

Tests

Tests includes the normal range of physical, chemical and environmental (weathering) tests which might be applied to the product
