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 using real or simulated colour problems. The unit will be assessed in as holistic a manner as is practical and may be integrated with the assessment of other relevant units of competency. Assessment will occur over a range of situations which will include a range of colours, problem causes and environments.

Simulation may be used for assessment of this unit of competency. Simulation should be based on the actual colour problems and should 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 define and analyse the problem as well as deal with the customer. The customer should be satisfied with the solution, as well as the solution being technically sound.

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

different types of problems can be analysed and resolved

different types of customers can be satisfied

the range of possible causes can be identified and analysed and the most likely cause determined

appropriate action is taken.

These aspects may be best assessed using a range of 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 history and similar sources.

Context of and specific resources for assessment

Assessment will require a suitable method of gathering evidence of colour problem solving 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.

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

Required skills

This competency requires the following skills:

communication

interrogation

observation

analysis

Required knowledge

Competence includes an understanding of colour and the interaction of colour components during processing and in application. A knowledge of the impact of weathering/aging on colour as appropriate to the product is also required. In particular it includes the ability to:

distinguish between colour variations caused by materials or processing errors

distinguish between colour variations caused by faulty surface preparation or application

interrogate customers to obtain all relevant information, but in a manner which is pleasing to the customer

explain the causes of colour variation in a manner which will be understood and accepted by the customer

describe the causes and remedies of common problems such as those selected in the 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 includes colour problems both in the plant and within the customer site (ie it includes both internal and external customers). This may include (select relevant items):

batches during manufacture do not conform to colour specification

colour as supplied to customer does not conform

colour as applied to substrate does not conform

colour variation within the product

colour was initially satisfactory but has changed over time

other colour problem.

Typical problem causes may include:

wrong colourant

wrong colourant amount

incorrect processing/mixing/dispersing

incorrect substrate preparation (eg of painted/printed surface)

incorrect application (eg of paint/ink)

incorrect colour measurement and testing

defect standard

process changes and variations.

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.
