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 prepare direct emulsion stencils 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

prepare TWO different direct screens using manual coating and exposure techniques according to manufacturers and job specifications 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 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

Coating techniques may include:

Type of stencil material may include:

Enterprise procedures may include:

Degree of autonomy may include:

Quality standards may include:
