Elements and Performance Criteria

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. 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) may also be included.

Critical aspects for assessment and evidence required to demonstrate competency

Evidence of the following is essential:

Correctly blend chemicals for ink and varnish manufacture according to job specifications
Demonstrate an ability to find and use information relevant to the task from a variety of information sources
Use EITHER a mixer / disperser OR a bead mill OR an automatic ink dispensing system to blend TWO batches of chemicals OR tint TWO batches of ink intermediates / concentrates 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 combined with review of portfolios of evidence and third party workplace reports of on-the-job performance by the candidate.
Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended.
