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:

reclaim screens using automatic cleaning equipment according to job specifications

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

maintain the equipment and reclaim THREE screens, with various grades of meshes and ink types using automatic equipment and 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:

assessment may take place on the job, off the job or a combination of both of theses. 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.

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.
