Evidence Required

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

correct interpretation of preproduction documentation to meet vision mixing requirements

collaborative approach to work

ability to mix a range of vision inputs according to production requirements

Context of and specific resources for assessment

Assessment must ensure

practical demonstration of skills through a range of vision mixing tasks in a television production environment

access to broadcasting facilities

access to appropriate learning and assessment support when required

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 combined with review of portfolios of evidence and thirdparty workplace reports of onthejob performance

evaluation of a selection of television programs for which the candidate mixed the vision

observation of the candidate in a vision mixing role

written or verbal questioning to test knowledge as listed in the required skills and knowledge section of this unit

Guidance information for assessment

Holistic assessment with other units relevant to the industry sector workplace and job role is recommended for example

BSBCRTA Collaborate in a creative process

BSBCRT402A Collaborate in a creative process.
