Elements and Performance Criteria

RANGE STATEMENT
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Procedures
All operations are performed in accordance with standard procedures and work instructions
Products
Products may include:
cups, saucers
tiles
bricks
sanitary ware
bathroom fittings
insulators
Equipment
Equipment may include:
belt feed hopper
dipping equipment
hand spray equipment
screen printers
silk screens
vibrating hoppers
Processes
Processes may include:
decorating
dry glaze/material
glaze fault repair
manual dip
manual spray
oversand spraying
reglaze (repaired products)
silk screen printing
waterfall/flinger/bell
wet glaze/material
Materials
Materials may include:
artwork
colours
cover coat
dry glaze dusts
frits
glazed products
liquid glaze
paints
sand
slurry
Typical problems
Typical problems may include:
glaze application faults (e.g. non-adherence or runs)
applicator equipment problems
product surface unsuitable for glaze application
glaze consistency
contamination
Occupational health and safety (OHS)
All operations are subject to stringent OHS requirements and these must not be compromised at any time. Where there is an apparent conflict between performance criteria and OHS requirements, the OHS requirements take precedence

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
The unit will be assessed in as holistic a manner as is practical and may be integrated with the assessment of other relevant units of competency.

Critical aspects for assessment and evidence required to demonstrate competency in this unit
Competence must be demonstrated in the ability to recognise situations requiring action and then in implementing appropriate corrective action. Consistent performance should be demonstrated. In particular look to see that:
glaze application is within requirements
equipment is used as required
glazing faults are recognised and categorised correctly.

Context of and specific resources for assessment
Assessment will require access to an operating plant over an extended period of time, or a suitable method of gathering evidence of operating ability over a range of situations.
Assessment will occur over a range of situations which will include disruptions to normal, smooth operation.
Simulation or case studies/scenarios may be required to allow for timely assessment of parts of this unit of competency. Simulation should be based on the actual plant and will include 'walk-throughs' of the relevant competency components. A bank of scenarios/case studies/what ifs and questions will be required to probe the reasoning behind observable actions.

Method of assessment
Individual enterprises may choose to add prerequisites and co-requisites relevant to their processes.

Guidance information for assessment
Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.
