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 the Training Package.

Overview of assessment

Assessment for this unit of competency will be by developing colour formulations in a plant, laboratory or other relevant context. Assessment will occur over a range of situations which will include different design briefs.

Simulation may be required for assessment of this unit of competency. Simulation should be based on actual colour formulation developments. Simulations may also include the use of case studies/scenarios and role plays.

This unit of competency requires a significant body of knowledge which will be assessed through questioning and the use of what-if scenarios.

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

Competence must be demonstrated in the ability to recognise and analyse potential situations requiring action and then in implementing appropriate corrective action. The emphasis should be on the predicting possible problems and determining actions required to avoid the difficulty.

Consistent performance should be demonstrated. In particular look to see that:

predicted colour formulations are reasonable

adjustments to formulations are made based on a rational interpretation of the results and an understanding of colour and the process

These aspects may be best assessed using a range of colour formulation development projects backed up by scenarios/case studies/what-ifs. These assessment activities should include a range of problems, including new, unusual and improbable situations which may have been generated from the past incident history of the plant, incidents on similar plants around the world, hazard analysis activities and similar sources.

Context of and specific resources for assessment

Assessment will require a suitable method of gathering evidence of colour formulation ability over a range of situations. A bank of scenarios/case studies/what-ifs will be required as will a bank of questions which will be used to probe the reasoning behind the observable actions.

Method of assessment

In all plants it may be appropriate to assess this unit concurrently with relevant teamwork and communication units.

Guidance information for assessment

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.

Required Skills and Knowledge

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

Required skills

This competency requires skills of:

communication

interrogation

observation

analysis

Required knowledge

Competence includes an understanding of colour, the interaction of colourants and the impacts of processing variables on the final colour of then product. In particular it includes the ability where relevant to:

interpret the 'flare path' on a tonal graph of tone vs time

choose the optimum grind/particle size for the required colour

balance gloss, opacity and tone

substitute colourants recommended from a 'computer match' for other colourants

make both metameric and non-metameric matches

determine the hazards arising from the colourants chosen

interpret weathering and other test data relevant to colour and the use of colour

describe the causes and remedies of common problems such as those selected in the Range Statement.

Competence also includes the ability to isolate the causes of problems to an item of equipment within the compressor system and to be able to distinguish between causes of problems such as:

wrong colourant

wrong colourant amount

wrong grind time/particle size

wrong wetting/dispersing.

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. Bold italicised wording, if used in the Performance Criteria, is detailed below. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs if the candidate, accessibility of the item, and local industry and regional contexts.

Codes of practice/ standards

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

Context

This unit of competency covers the development of a new colour formulation 'from scratch', usually based on a provided colour sample. The formulation would normally use colourants already available within the company (preferred colourants), but does not preclude the use of colourants which are novel/new to the company. It may be applied to any industry sector requiring the development of a new colour formulation such as:

paint

ink

plastics

rubber

concrete products

glass products

clay/ceramic products.

Typical problems

Typical problems may include:

matching under different lighting conditions

variable surface finish/gloss level

non-metameric matching

process caused colour differences.

Health, safety and environment (HSE)

All operations to which this unit applies 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 HSE requirements take precedence.
