Evidence Guide

EVIDENCE GUIDE 

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:

  • the plate is processed according to the plate manufacturer's specifications. Changes to the plate image are carried out correctly to deliver the standard of output required by the job brief
  • the underlying skills of plate making should be transferable across the design and pre-press sectors. It is important that the substrate for reproduction is identified and that the quality of the plate be suitable for the identified printing processes
  • demonstrate an ability to find and use information relevant to the task from a variety of information sources
  • prepare, set up and use lithographic plate exposure and plate processing equipment to produce ONE lithographic plate manually and ONE using a machine according to the listed Performance Criteria.

Context of and specific resources for assessment 

Assessment must ensure:

  • that conditions are typical ambient conditions found in the workplace
  • access to relevant facilities, equipment, materials and special purpose tools
  • use of culturally appropriate processes and techniques appropriate to the language and literacy capacity of learners and the work being performed.

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.
