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 following is essential:

correctly manufacture inks and coatings according to job specifications

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

use a mixer/disperser and EITHER a bead mill OR a 3-roll mill to manufacture TWO batches of ink/coating according to manufacturer's and job specifications, OHS requirements, enterprise procedures and the listed Performance Criteria.

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.

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/observation combined with review of portfolios of evidence and third party workplace reports of on-the-job performance by the candidate.

Guidance information for assessment

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

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance.
