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

Assessment must be carried out in a manner that recognises the cultural and literacy requirements of the assessee and is appropriate to the work performed. Competence in this unit must be achieved in accordance with food safety standards and regulations.

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

Evidence of ability to:

prepare products and materials, including weighing and measuring as required

set up and operate equipment

additions and finings are added according to specification

ensure control points are monitored and appropriate corrective action is taken for out-of-specification product, process and equipment performance

collect unused materials and waste, and store, treat or dispose of appropriately

use personal protective equipment and follow other OHS procedures

record information appropriately.

Context of and specific resources for assessment

Assessment must occur in a real or simulated workplace where the assessee has access to:

personal protective clothing and equipment as required

work procedures, including advice on company practices, safe work practices, food safety, quality and environmental requirements

instructions, information, specifications and schedules as required

equipment, services and corresponding information as required

products and materials as required

internal and external customers and suppliers as required

cleaning procedures, materials and equipment as required.

Method of assessment

This unit should be assessed together with other units of competency relevant to the function or work role.

Guidance information for assessment

To ensure consistency in one's performance, competence should be demonstrated on more than one occasion over a period of time in order to cover a variety of circumstances, cases and responsibilities, and where possible, over a number of assessment activities.

Required skills include:
