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 processes and techniques must be culturally appropriate and appropriate to the language, literacy and numeracy capacity of the candidate and the work being performed.

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

Assessors must be satisfied that the candidate can competently and consistently:

interpret work order/job instruction and locate and apply relevant information to operate glass silvering equipment

plan and prepare for the conduct of glass silvering operations

conduct glass silvering operations

apply safe handling requirements for equipment, products and materials, including use of personal protective equipment

follow work instructions, operating procedures and inspection practices to:

minimise the risk of injury to self and others

prevent damage to goods, equipment and products

maintain required production output and product quality

as a minimum:

prepare silvering formulae

perform equipment checks

set up and prepare silvering equipment

clean and prepare glass for silvering

apply tinning, silvering and copper solutions on glass

dry and apply packing paint

strip, buff, clean, prepare and re-silver mirrors

handle and store mirrors

clean solution tanks, lines, spray guns and equipment after use

work effectively with others.

Context of and specific resources for assessment

The application of competency is to be assessed in the workplace or realistically simulated workplace.

Assessment is to occur under standard and authorised work practices, safety requirements and environmental constraints.

Assessment of essential underpinning knowledge, other than confirmatory questions, will usually be conducted in an off-site context.

Assessment is to comply with relevant regulatory or Australian Standard requirements.

The following resources should be made available:

glass silvering equipment

demineralised water

acid

silvering chemicals

backing paint

workplace operating procedures

unprocessed materials

personal protective equipment

an appropriate work area.

Method of assessment

Assessment must satisfy the endorsed Assessment Guidelines of the LMF02 Furnishing Industry Training Package.

Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge.

Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure correct interpretation and application.

Assessment may be applied under project-related conditions (real or simulated) and require evidence of process.

Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.

Assessment may be in conjunction with assessment of other units of competency.
