Overview of assessment

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

Evidence of the following is essential:

reclaim screens, preferably of different mesh and stencil types commonly used in the industry, using manual techniques, according to job specifications

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

reclaim THREE screens, preferably of different mesh and stencil types commonly used in the workplace, using manual techniques, according to manufacturer's and job specifications, enterprise procedures and the listed Performance Criteria.

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:

skills and knowledge are demonstrated in a range of situations and in an environment that realistically reflects the workplace

access to a range of relevant tools, equipment, materials, resources and documentation used when reclaiming screens in the printing industry

application of the most current workplace procedures, processes and techniques used in the printing industry.

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.

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. Bold italicised wording, if used in the performance criteria, is detailed below.
