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

Evidence of the ability to

should meet client requirements and enterprise and industry standards

demonstrate an ability to find and use information relevant to the task from a variety of information sources

prepare at least TWO different lots of ink and additives that require special colour matching and match colour sample by manual and electronic means to job specification industry standards and listed performance criteria Ideally each lot of ink should be a different type for use on a different substrate

evidence for assessment may be gathered from assessment of the unit of competency alone or through an integrated assessment activity

Context of and specific resources for assessment

Assessment must ensure

assessment may take place on the job off the job or a combination of these Off the job assessment must be undertaken in a closely simulated workplace environment

inks and additives

Method of assessment

A range of assessment methods should be used to assess practical skills and knowledge The following examples are appropriate for this unit

direct questioning combined with review of portfolios of evidence and third party workplace reports of onthejob performance by the candidate

Guidance information for assessment

Holistic assessment with other units relevant to the industry sector workplace and job role is recommended
